FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with chorea is indexed in search engines, such as www.google.com or others, a nonsystematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about chorea, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to chorea, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on chorea. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to chorea, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on chorea. The Editors

CHAPTER 1. STUDIES ON CHOREA Overview In this chapter, we will show you how to locate peer-reviewed references and studies on chorea.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and chorea, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “chorea” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Alzheimer's Disease and Dementing Disorders Source: Physical Medicine and Rehabilitation: State of the Art Reviews. 4(1): 9-17. February 1990. Summary: Dementia is a major cause of disability in the elderly. Alzheimer's disease and multiple brain infarctions account for more than 80 percent of patents with dementia. The rest suffer from other disorders such as Pick's disease, Parkinson's disease, Creutzfeldt-Jakob disease, Huntington's chorea, multisystem atrophy, and progressive supranuclear palsy. Other causes of dementia are potentially reversible, such as subdural hematoma, brain tumors, or normal pressure hydrocephalus. Subacute and chronic infections of the central nervous system (CNS) can also cause dementia, such as syphilis, AIDS, and cryptococcal meningitis. Factors extrinsic to the CNS may cause dementia, which is often preventable, arrestable, or reversible. Examples include

Chorea
drug intoxication, liver disease, thyroid disorders, high or low blood sugar, and thiamine deficiency. Lastly, mental depression in the elderly can sometimes mimic dementia. The etiology of Alzheimer's disease remains unknown, although evidence suggests a genetic factor. Experimental treatment of Alzheimer's disease with cholinergic agents has met with limited success. Reversible disorders must be ruled out prior to the diagnosis of Alzheimer's dementia in the elderly patient. 42 references. •
Implant-Supported Denture in a Patient with Huntington's Disease: Interdisciplinary Aspects Source: SCD. Special Care in Dentistry. 21(1): 15-20. January-February 2001. Contact: Available from Special Care Dentistry. 211 East Chicago Avenue, Chicago, IL 60611. (312) 440-2660. Summary: Patients with Parkinson's disease or Huntington's chorea often cannot maintain independent, efficient oral hygiene due to restricted motor ability of the upper extremities and lack of coordination. The hermetic closure of the mouth and lips, and the associated ability to keep liquid and toothpaste in the mouth, can become so weak that effective oral hygiene cannot be maintained. Over a period of many years, this illness leads to loss of teeth and the need for complete prosthodontic care. Dyskinesia and hyperkinesia of the tongue and the peri oral musculature, combined with xerostomia (dry mouth) and pooling of saliva, make it impossible for the patient to wear a conventional complete denture, despite an anatomically adequate bearing area. In such cases, an implant supported prosthesis is a better therapeutic measure, although some aspects of oral hygiene must initially be disregarded. This article reports the case of a patient with Huntington's chorea, in whom two ITI implants were inserted into the anterior mandibular (lower jaw) region. The implants were used because a complete denture could not be retained on the alveolar ridge, despite adequate vestibule depth, due to tongue dyskinesia. A bar joint was used to anchor this mucosal borne denture. This implant supported complete denture led to a clear improvement in the patient's chewing function when observed over a period of a year. The authors conclude that, given interdisciplinary cooperation between the attending neurologist and the dentist or oral surgeon, treatment by means of an implant supported prosthesis should be possible, even for patients with the most severe neurological symptoms, on a case by case basis, taking all relevant modifying factors into account. 3 figures. 27 references.

Dental Management of a Child with Huntington's Disease: Case Report Source: SCD. Special Care in Dentistry. 13(2): 71-73. March-April 1993. Summary: This article presents a case report of the dental management of a child with Huntington's disease (HD), a chronic, progressive hereditary disorder characterized by chorea, behavioral changes, dementia, and irregular gait. Dyslalia is a common feature due to the severe darting movements of the tongue and head. This case report features an 11 year old white male, diagnosed at age 5, who was brought to the University of Minnesota Hospital Dental Clinic for an oral examination. The findings are presented, and the management of patients with HD are discussed. The authors conclude that if any dental treatment is rendered to HD patients it should be basic, including exodontia, simple operative, non-surgical periodontal therapy. Endodontics, crowns, and bridges are not indicated. Dentures or appliances of any kind are contraindicated. 6 references. (AA-M).

Dementia Syndromes: Distinguishing Their Clinical Differences Source: Postgraduate Medicine. 95(5): 91-93, 97-101. April 1993. Summary: This article reviews the clinical differences in various dementia syndromes. It includes the primary dementias: Alzheimer's disease, Pick's disease, alcoholic dementia syndrome, and Marchiafava-Bignami disease; dementias associated with other neurologic deficits; and dementias that associate with other illnesses. Primary care physicians can help patients and their families by recognizing the differences in pathophysiology and clinical presentation among these forms of dementia. Other principal forms of dementia examined include multi-infarct dementia, Parkinson's disease, progressive supranuclear palsy, Creutzfeldt-Jakob disease, Huntington's chorea, acquired immunodeficiency syndrome dementia, neurosyphilis, and hypothyroidism. Final comments examine practical and important aspects of laboratory workup in patients with dementia to find treatable causes of reversible syndromes. 15 references.

Rheumatic Fever: No Cause for Complacence Source: Patient Care. 34(14): 40-42,45-46,53,57,61. July 30, 2000. Summary: This journal article provides health professionals with information on the epidemiology, clinical characteristics, diagnosis, treatment, and prevention of rheumatic fever. This inflammatory disorder of the connective tissue can affect the heart, joints, brain, and cutaneous and subcutaneous tissues. Cardiac damage is the only potentially chronic debilitating effect. Factors with a role in the etiology of this disease include socioeconomic status, environmental factors, and heredity. The epidemiology of rheumatic fever is linked to that of streptococcal pharyngitis because it occurs most frequently in the spring following the peak period of streptococcal pharyngitis. Clinical manifestations, which usually occur 1 to 3 weeks after the onset of pharyngitis, include arthritis, carditis, chorea, erythema marginatum, and subcutaneous nodules. Diagnosis is based on the presence of two major criteria or one major criteria and two minor criteria. Conclusive evidence of a preceding streptococcal infection must be present to confirm the diagnosis of rheumatic fever. Treatment consists of an intramuscular injection of 1.2 million U of long acting bezathine penicillin G. Aspirin should be started as soon as the diagnosis is suspected. Treatment lasts for 3 to 4 weeks, but when carditis is present, treatment may be required for 6 to 8 weeks. Corticosteroids are used primarily when severe carditis with congestive heart failure occurs. Rheumatic fever may recur with subsequent streptococcal infections, so penicillin may be administered. Sulfadiazine and erythromycin may be substituted when penicillin cannot be used. Sequelae include mild mitral insufficiency and aortic insufficiency. 3 figures, 3 tables, and 4 references.
Federally Funded Research on Chorea The U.S. Government supports a variety of research studies relating to chorea. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of 2

federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to chorea. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore chorea. The following is typical of the type of information found when searching the CRISP database for chorea: •
Project Title: A NATIONAL RESOURCE FOR POSTMORTEM BRAIN RESEARCH Principal Investigator & Institution: Benes, Francine M.; Professor of Psychiatry (Neuroscience); Mc Lean Hospital (Belmont, Ma) Belmont, Ma 02478 Timing: Fiscal Year 2003; Project Start 17-SEP-2003; Project End 31-JUL-2008 Summary: (provided by applicant): This is a competitive renewal application for the Harvard Brain Tissue Resource Center, a national resource for the acquisition, processing, storage and distribution of high quality postmortem (PM) brain to the neuroscience community. This facility collects brains from normal controls (CON), as well as individuals with a variety of movement disorders (Huntington's chorea and Parkinson's disease), dementias (Alzheimer's disease, frontotemporal dementias) and major psychoses (schizophrenia and bipolar disorders). The HBTRC distributes tissue specimens to neuroanatomists, neuropathologists, neuropharmacologists, neurochemists and molecular biologists throughout the U.S. Over the past 5 years, this tissue has contributed to more than 170 scientific publications. During the current funding period, the HBTRC has undergone a major restructuring that has resulted in an increase in the overall quality and efficiency of its operation. An important outcome of this re-organization has been an increase in the number of fresh, frozen cases and a marked decrease in the postmortem interval (PMI). As a result of this effort, abundant, high quality tissue is now available for a broad array of state-of-the-art research applications. The number of CONs received by the HBTRC has more than doubled during the current funding period and the HBTRC is now able to provide investigators with sets of CONs and diseased brains matched for age, PMI, gender and hemisphere. For the major psychoses, where the acquisition of postmortem brains is actually challenging, the number of schizophrenic and bipolar cases has also increased. Since these are largely from community-based referrals, the potential confounding effects of institutionalization, inanition and substance abuse are relatively lower than in medical examiner cases. To facilitate the donation process, the HBTRC has established a website with a) Informed Consent forms for potential donors and their families, b) instructions for handling brains by pathologists or dieners involved in brain removal, and c) application forms for investigators seeking tissue for their research. The HBTRC has also developed a User-Interactive Database, so that investigators who receive tissue from the "bank" can obtain demographics, neuropathology reports and images of gross dissections and histological slides for their cases. With supplemental funding from NIH, the HBTRC is now obtaining gene expression profiling and SNP analyses using the standard Affymetrix microarray system and this information will be immediately placed in our public domain National Databank as it is obtained. All investigators receiving tissue from the HBTRC will also be encouraged to "deposit" their findings in the Databank so that they will be available to the neuroscience community for complex

Principal Investigator & Institution: Trifiletti, Rosario R.; Assistant Professor; Weill Medical College of Cornell Univ New York, Ny 10021 Timing: Fiscal Year 2002; Project Start 01-DEC-2001; Project End 30-NOV-2002 Summary: Recent evidence suggests that Sydenham chorea, obsessive/compulsive disorder and Tourette syndrome may have a similar autoimmune basis. Dr. Zabriskie and co-workers have shown that a specific B-cell D8/17 clonal marker is greatly expanded in all of these groups. The goal of the present study is to correlate brain autoantigens, B-cell clonal status and neurologic, psychaitric and cognitive outcome in all of these groups. If correlations are found, efforts will be made to isolate the respective autoantigens. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: BASAL GANGLIA CIRCUITRY IMMEDIATE EARLY GENE EXPRESSION Principal Investigator & Institution: Wirtshafter, Robert D.; Psychology; University of Illinois at Chicago 1737 West Polk Street Chicago, Il 60612 Timing: Fiscal Year 2002; Project Start 01-DEC-1998; Project End 31-DEC-2003 Summary: (from Abstract) The long term objective of the current proposal is the attainment of a greater understanding of the functional organization of the basal ganglia. Substantial evidence suggests that many neurological and psychiatric disorders, including Parkinson's disease, Huntington's disease, Sydenham's chorea, torsion dystonia, Tourette's syndrome and schizophrenia, may result from abnormalities in the activity of these nuclei. Progress in understanding the etiology of these disorders, and in developing treatments for them, is largely dependent on advances in understanding the basic nature of basal ganglia functioning. The proposed experiments are designed to examine basal ganglia by using the immunocytochemical detection of immediate early genes (IEGs) as markers for neurons affected by various behavioral or pharmacological manipulations. The striatum is the largest nucleus within the basal ganglia and is the primary terminus of input into this system. The first set of studies will examine the pharmacological and behavioral control of IEG expression within this structure with emphasis on the patterning of IEG expression with respect to the striosome/matrix compartmentation of the striatum. The striatum contains a number of neuroactive compounds including dopamine, serotonin, adenosine, acetylcholine and substance P and the role played by these substances in controlling striatal IEG expression will be examined. The applicants will also examine the role of dopamine in IEG expression induced by shuttling behavior and characterize the cells that express IEGs under these conditions. Events occurring within the striatum can only influence behavior by affecting the activity of neurons within other parts of the brain. The second group of studies will therefore use IEG expression as a tool to investigate the basic organization of extrastriatal circuitry related to the basal ganglia. Experiments will examine the ability drugs microinjected directly into the striatum, or other basal ganglia nuclei, to influence IEG expression at extrastriatal sites. Other studies will examine the effects of

Project Title: CHOLINERGIC REGULATION OF THE CIRCADIAN CLOCK Principal Investigator & Institution: Gillette, Martha U.; Professor; Cell and Structural Biology; University of Illinois Urbana-Champaign Henry Administration Bldg Champaign, Il 61820 Timing: Fiscal Year 2002; Project Start 01-AUG-1997; Project End 31-MAY-2005 Summary: (provided by applicant): Acetylcholine (ACh) has diverse regulatory roles in the central nervous system. Cholinergic neurons in brainstem and basal forebrain structures send ascending fibers throughout the brain where they may participate in a wide range of functions, including modulation of learning, memory retrieval, mood states, central autonomic control, and the processes regulating sleep/arousal. Mechanisms by which cholinergic signals induce long-lasting changes in neuronal state, and their consequences for behavior, are areas of intense research interest with great importance for human health. We propose to investigate mechanisms of cholinergic signaling via M1 mAChRs (M1.Rs) to behaviorally relevant hypothalamic neurons and immortalized cells from rat, as well as in transgenic mouse models. Imaging of M1.R distribution within the suprachiasmatic nucleus (SCN) reveals substantial receptor concentrations. We have found that M1 subtype-like pharmacological reagents selectively alter the cholinergic response. Preliminary data using transgenic mice and immortalized cell lines support the pharmacology and point to this brain site as an important model in which to evaluate M1.R signaling. We propose to employ techniques ranging from behavioral analyses to extracellular and patch-clamp recordings in brain slices, accompanied by immunocytochemical, biochemical and cell biological approaches, together aimed at uncovering fundamental mechanisms of M1.R signaling. Our specific aims include: 1) To fully evaluate the effect of genetic deletion of the M1.R on the cholinergic response, 2) To assess actions of downstream diffusible messengers, and 3) To define the role of specific PKG isoforms in this M1.R signaling cascade. In addition to making fundamental contributions to understanding muscarinic neuromodulation of CNS neurons, these studies will permit us to evaluate the roles of M1.R-mediated neurotransmission within a defined behavioral axis. This

multidisciplinary approach will provide new insights into central cholinergic neurotransmission, muscarinic signal transduction mechanisms, and decision-making processes that form the neural substrates of behavioral change. Signal transduction is a cellular process, and by identifying the roles of specific receptors, second messenger systems and targets, we will be able to understand the causal mechanisms that mediate long-term adjustments in neuronal state. This research has applied relevance for strategies in developing rationally-based therapies for cholinergic disorders, including those altering sleep/arousal, autonomic function, senile dementia, Alzheimer's type (SDAT), Parkinson's disease, Huntingtons chorea and other neuropsychiatric and movement disorders.

Project Title: PROCESSING
CORTICOSTRIATAL
INFLUENCES
ON
NEOSTRIATAL
Principal Investigator & Institution: Alloway, Kevin D.; Professor; Neuroscience and Anatomy; Pennsylvania State Univ Hershey Med Ctr 500 University Drive Hershey, Pa 170332390 Timing: Fiscal Year 2002; Project Start 01-JUL-1999; Project End 30-JUN-2007 Summary: (provided by applicant): The neostriatum and related parts of the basal ganglia contain functional channels that separately process prefrontal, limbic, oculomotor, and sensorimotor information received from the cerebral cortex. Although the specific cortical areas that activate each functional channel are different, each channel contains the same basic input-output pattern of connections. By using cutaneous stimuli to activate corticostriatal projections from somatosensory cortex, we can characterize the pattern recognition properties of neostriatal neurons and determine how neural activity in the sensorimotor channel is coordinated during sensory stimulation. Hence, this paradigm presents a unique opportunity for understanding the rules that govern the dynamic operation of corticostriatal circuits across all functional channels because there are no accepted methods for directly activating limbic or prefrontal channels in a controlled, naturalistic manner. The anatomic and physiologic properties of the neostriatum represent a significant issue in contemporary neuroscience because this brain region has been implicated in Parkinson's disease, Huntington's chorea, Tourette's syndrome, and schizophrenia. In this project we will use anterograde tracing methods to test the hypothesis that corresponding representations in the primary and secondary somatosensory cortical areas send convergent projections to the neostriatum. We will also use retrograde tracing techniques to verify previous results indicating that corticostriatal projections from somatosensory cortex have an anisostropic organization. We will also compare corticostriatal and corticopontine projections to determine if the corticopontine projections follow the same principles of organization that have been identified in the corticostriatal system (ie. Principles of Cortical Proximity, Somatotopic Homology, and Behavioral Cooperativity). Finally, we will record neuronal activity in multiple parts of the cerebral cortex and neostriatum so that we may analyze neuronal interactions between the cortex and neostriatum. These physiology studies will determine whether a primary function of neostriatal neurons is to detect synchronized activity among functionally-related cortical areas.

Project Title: DEVELOPMENT OF PET RADIOLIGANDS FOR NMDA RECEPTORS Principal Investigator & Institution: Waterhouse, Rikki N.; Assistant Professor of Neuroscience; Psychiatry; Columbia University Health Sciences Po Box 49 New York, Ny 10032 Timing: Fiscal Year 2003; Project Start 15-DEC-2002; Project End 30-NOV-2004 Summary: (provided by applicant): Alterations in normal NMDA channel subunit composition and function are implicated in the pathophysiology of certain neurological and neuropsychiatric disorders such as Parkinson's Disease, Huntington's Chorea, schizophrenia, alcoholism and stroke. Binding of NMDA ligands to succinct modulatory sites located on the outside of or within the ion channel serves to modulate behavioral and neurochemical responses. For this proposal, the NMDA/PCP site has been specifically chosen as an imaging target since the involvement of this site in cognitive and neurodegenerative processes and psychotic behaviors is well documented. The development of effective PET tracers for the study of NMDA receptors is critical to providing much needed tools for understanding of the etiology and improving the clinical management of disorders thought to involve the associated ion channel. The PCP site is located inside the ion channel. Effective PCP site tracers will bind their target selectively during the active and "open" state of the ion channel. Therefore, an effective PCP site tracer would serve as a non-invasive in vivo tool to report on the functional state of the channel. In addition to providing information regarding channel activation, these tracers would also be able to monitor the density of these sites. To identity effective PCP site tracers, novel substituted N, N'-alkyl-diphenyl guanidines will be synthesized and evaluated. Candidate ligands possessing high affinity, selectivity, and appropriate lipophilicity will be radiolabeled and further characterized in in vitro assays and in vivo models. In addition to aspects of radiotracer design synthesis, specific issues regarding appropriate methods to evaluate the new tracers for effective labeling of the ion channel in vivo will be addressed. To supplement the more classical methods of PET radiotracer evaluation, we will adopt an ex vivo method for determining the degree of in vivo saturable binding that occurs with these ligands. While well-established cell membrane assays will be used, an additional modified in vitro assay will allow us to probe the nature of binding of tracers to closed and open states of the channel. The use of these models will provide additional information to assist in the development of clinically useful PCP site radioligands. The data obtained will be pivotal for the design of studies to non-invasively assess NMDA receptor function and will identify suitable radiotracers and provide preliminary data to support future grant submissions.

Project Title: DOPAMINE TRANSPORTER IMAGING WITH FLUORINE-18 PET Principal Investigator & Institution: Neumeyer, John L.; Professor ( Emeritis), Director of Medic; Natural Pharmacia International, Inc. 115 Mill St Belmont, Ma 02478 Timing: Fiscal Year 2002; Project Start 01-JUN-2000; Project End 30-APR-2004 Summary: (provided by applicant):Positron emission tomography (PET) is sensitive and specific non-invasive imaging technology that can provide information about the functional status of neurotransmitter systems in-vivo. Recent efforts have focused on the development of PET-based radiotracers for use in studies of the dopamine transporter (DAT) abundance and pharmacology Changes in the density and function of DAT have been implicated in neurodegenerative and neuropsychiatric diseases such as Parkinson?s disease, major depression, Huntington's chorea, schizophrenia, and attention deficit-hyperactivity disorders (ADHD).

fluorine-18 labeled tropane derivatives, such as FP-C1T, in which the N-methyl group of the tropane was replaced by a [S18FJ fluoropropyl group. During the Phase I project, we characterized the cerebral monoamine transporter binding affinity of a series of novel fluoralkyl-containing tropane derivatives, which showed higher DAT affinity and selectivity than FP-C1T. These new ligands are attractive candidates for development of ?8F-labeled PET radiotracers for clinical imaging DAT in human brain. Our objectives on this Phase II project are to further synthesize and pharmacologically evaluate novel N- or 0-fluoroalkyl tropane derivatives with a view toward one-step simplified 18Fradiolabeling. The most promising compounds' physiochemical properties (lipophilicity) will be evaluated. A facile and rapid method of synthesis of 18F labeled tropane derivatives will be developed for the most promising compound(s). The lead compound in this series (presently BRL-308) will be evaluated by PET imaging and pharmacokinetics, in non-human primates.

Project Title: FUNCTIONAL NEUROANATOMY OF MOVEMENT DISORDERS Principal Investigator & Institution: Brown, Lucy L.; Associate Professor; Neurology; Yeshiva University 500 W 185Th St New York, Ny 10033 Timing: Fiscal Year 2002; Project Start 01-APR-1998; Project End 31-MAY-2007 Summary: (provided by applicant): Although the gene for Huntington's disease (HD) has been identified, the processes that lead to cell pathology and degeneration are still unclear. The proposed studies examine early pathology and pathophysiology in two transgenic mouse models of Huntington's disease. Our preliminary data in one mutant model, the reversible HD94 model, suggest that the chemoarchitecture of the striatum is altered in early symptomatic stages of the disease: there are more mu opioid receptorrich striosomes in mutants than in controls, which may lead to an imbalance of activity between the striosome and matrix compartments and produce the symptoms of chorea and involuntary activity. The studies will determine whether there are more striosomes in mutants by using immunocytochemical methods to identify striosomes. The working hypothesis states that the early stages of the disease are associated with abnormal developmental processes. The specific hypothesis is that a critical part of the pathology underlying the symptoms and final degenerative process of Huntington's disease is abnormal neurogenesis prenatally and postnatally, and that the number of striosomes in mutants reflects neurogenesis abnormalities. In addition, our model of the behavioral functions of striosomes predicts that mutants will be more sensitive to dopamine agonists. Finally, the studies will investigate prenatal and adult cell proliferation and neurogenesis in mutants and their controls by using a thymidine analogue, bromodeoxyuridine (BrdU). The studies may provide clues to the function of the gene huntingtin, and define a target for therapeutic strategies. In addition, these studies address the plastic and proliferative capacity of the adult brain. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Chorea
Summary: (Applicant's Abstract) Psychostimulant abuse is a considerable problem in society. Both cocaine and amphetamine are widely used, and the use of methamphetamine on the rise. These psychostimulant drugs produce their reinforcing effects via interactions with the dopamine transporter, cocaine by inhibiting dopamine uptake (the inward flow of dopamine into the neuron), and amphetamines by stimulating dopamine release via reversal of the transporter. These actions result in an increase in extracellular dopamine, which then interacts with dopamine receptors to increase dopaminergic transmission. In order to develop a treatment for the abuse of these substances, it is necessary to find a mechanism by which the activity of the dopamine transporter and dopamine receptors can be regulated. Repeated administration of a selective kappa-opioid agonist produces a down-regulation of the dopamine transporter, and of dopamine D: receptors, suggesting that the kappa-opioid regulation of dopamine neurotransmission might provide a mechanism by which to alter the effects of psychostimulants such as cocaine and amphetamine. The specific hypothesis of this proposal is that the dopamine transporter can be regulated via manipulations of kappa-opioid receptors, and that this will alter the neurochemical, and hence the behavioral effects of psychostimulant drugs such as cocaine and amphetamine. Specifically, the anatomical and pharmacological alterations in the dopamine transporter and dopamine receptors, as well as the associated behavioral changes, will be measured following chronic administration of kappa-opioid receptor agonists. We will measure receptor binding using in vitro autoradiography and homogenate binding. Dopamine transporter function will be measured using dopamine uptake and release assays, and dopamine receptor function will be evaluated using adenylyl cyclase and GTPgammaS binding assays. Behavior will be measured using locomotor activity studies. Understanding of the regulation of dopamine neurotransmission by kappa-opioid receptor agonists will provide leads to the development of a therapeutic agent for treating abuse of psychostimulant drugs. Altered dopamine receptor function has been implicated in numerous neurological disorders including schizophrenia, Parkinson's disease, Tourette's syndrome, and Huntington's chorea, in addition to psychostimulant drug abuse. Treatments for most of these syndromes involve use of agonists and antagonists at particular receptors, a state that often leads to marked side effects. Hence, the ability to regulate dopaminergic transmission via alterations of the dopamine transporter would be useful in the treatment of such syndromes.

Project Title: LONGITUDINAL STUDIES AMONG AT-RISK HD GENE CARRIERS Principal Investigator & Institution: Foroud, Tatiana M.; Associate Professor; Medical and Molecular Genetics; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, in 462025167 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2007 Summary: (provided by applicant) To identify and quantify changes among presymptomatic Huntington disease gene carriers who had not yet developed definite chorea, we performed the largest, study of individuals at-risk for HD (n=657) Subtle abnormalities in oculomotor, extrapyramidal and pyramidal motor, and cognitive measures were identified. We propose to reexamine this unique sample of at-risk individuals using an expanded test battery that includes more sensitive and specific quantitative measures for each subset of variables for which significant differences between presymptomatic gene carriers and nongene carriers were initially observed. These new measures increase the power of our proposed longitudinal studies of the rate

of change among presymptomatic gene carriers as they approach the manifestation of clinically diagnosable HD. These novel studies are designed to: 1) Further delineate the deficits observed in the subclinical and early symptomatic phase of disease; 2) measure the rate of increasing abnormality among presymptomatic gene carriers; 3) investigate the interrelationships among the variables so as to identify measures with similar rates of deterioration, which might suggest common pathways affected early in the disease process; 4) quantify the relationship of CAG repeat number with disease onset and progression. The results of these studies will improve the understanding of the presymptomatic and early symptomatic phase of HD allowing for earlier diagnosis and identify subclinical biomarkers that can be utilized in clinical trials to evaluate therapeutic agents designed to slow progression and delay the onset of clinical HD.

Project Title: MECHANISMS NEURODEGENERATION
OF
HUNTINGTIN-INDUCED
Principal Investigator & Institution: Finkbeiner, Steven M.; Assistant Professor; J. David Gladstone Institutes Box 419100, 365 Vermont St San Francisco, Ca 94103 Timing: Fiscal Year 2002; Project Start 01-JUL-2000; Project End 30-JUN-2004 Summary: (adapted from applicant's abstract): Huntington disease (HD) is a devastating inherited neurodegenerative disease characterized by chorea, dementia, and premature death. It is caused by a mutation within the gene IT15 that encodes an abnormally long stretch of polyglutamines (polyGlns) within the protein huntingtin (htt). The overall goal of our research is to elucidate the molecular mechanisms by which mutant htt induces neurodegeneration. We have developed a cellular model that recapitulates two key features of Huntington's disease: cultured neurons transfected with mutant htt die in a mutation (polyGln expansion)-dependent fashion and the death is cell-specific, affecting only the enkephalin-positive striatal neurons in culture. Htt is expressed widely in the nervous system, so the basis for neuron-specific degeneration in Huntington's disease is unknown. Using the model, we found evidence that mutant htt must translocate from the cytoplasm into the nucleus to trigger neurodegeneration, but the mechanisms that regulate the translocation are not known. How htt acts in the nucleus to trigger neurodegeneration is also unclear. Preliminary experiments with our model suggest that expanded polyGln tracts may alter htt to promote gene expression in a mutation-dependent and transcription factor-specific manner. However, the molecular basis for the effect of mutant htt on gene expression is unknown. To begin to address these unanswered questions, we propose to use our cellular model to accomplish the following Specific Aims: 1) Characterize the mechanisms of neuron-specific degeneration in Huntington's disease by varying independently the type of neuron in which mutant htt is expressed, the expression level of mutant htt, and the protein context in which the polyGln tract is expressed; 2) Characterize the critical processes by which htt is translocated to the nucleus by characterizing the factors that normally regulate htt localization and by mapping within the gene that encodes it, sequences that function to localize it to the cytoplasm, translocate it to the nucleus, or restrict it to sub domains of the nucleus and; 3) Identify mechanisms by which mutant htt, acting in the nucleus, could trigger neurodegeneration by elucidating the molecular mechanisms by which mutant htt potentiates gene expression mediated by the transcription factor Sp1, and by using microarray technology and inducible expression to identify the earliest changes in endogenous gene expression triggered by mutant htt. Completion of these aims should reveal new insights into general mechanisms of neurodgeneration and to the identification of potential molecular targets for new HD therapies.

Project Title: MECHANISMS OF STREPTOCOCCAL/HOST INTERACTION Principal Investigator & Institution: Zabriskie, John; Rockefeller University New York, Ny 100216399 Timing: Fiscal Year 2002 Summary: We have now completed our studies on the nature of the nephritogenic protein using the sera and renal biopsies from patients with acute post streptococcal glomerulonephritis (APSGN). All nephritogenic strains produce a protein called nephritis plasmin binding protein (NPBP) which was isolated, sequenced and found to be identical with streptococcal proteinase or streptococcal pyrogenic exotoxin B (SPEB). Using antibodies prepared against recombinant SPEB, 65% of 20 APSGN biopsies were found to contain the antigen in the glomerulus while only 4% of 25 non APSGN biopsies were positive. None of the biopsies were positive for streptokinase, another streptococcal antigen possibly associated with APSGN. APSGN sera reacted preferentially with this antigen when compared to sera from patients with either rheumatic fever or uncomplicated streptococcal infections and normal controls. Furthermore, serial serum studies of APSGN patients revealed that while the titers decreased over one year they never returned to baseline values suggesting a possible protective effect against the known fact that recurrences of APSGN are extremely rare. A manuscript detailing these findings has been submitted to Kidney International. Studies involving the rheumatic fever marker D8/17 have proceeded along two areas of investigation. The first is concerned with the predictive role of the marker for disease susceptibility. Approximately 3,000 children ages 5-10 years who come from high risk areas of rheumatic fever in Mexico City have been tested for the marker. Seven percent of these unaffected children are positive for the marker. All children are being followed over time for the appearance of rheumatic fever. If our hypothesis is correct, only those positive for the D8/17 marker will be susceptible. The second area of investigation of the marker was unexpected. In collaboration with a group from Child Psychiatry at NIH under the direction of Dr. Sue Swedo, we have examined the presence or absence of this marker in a group of 23 children (and appropriate controls) with obsessive-compulsive disorders (OCD). In a double blind test the marker correctly identified ninety percent of the OCD patients compared to the expected 7% controls. In view of the known crossreactions between streptococcal antigens and caudate nucleus cells, these studies suggest that other brain-streptococcal cross reactive antigens may be involved in the OCD syndrome. A manuscript detailing these findings has been sent to the J. Child Psychaitry. Our more basic approach to the exact nature of the D8/17 antigen and caudate binding antigen in the sera of Sydenham's chorea are being pursued along two main lines of investigation. Concerning the D8/17 antigen our main problem in identifying this antigen has been the fact that the antibody is the IgM class. Thus nonspecific binding of other proteins has resulted in identification of a number of bands. Secondly, this antibody does recognize other antigens expressing a coil-coiled structure. We have recently isolated a IgG clone of the D8/17 antibody and hope this will have the same specificity as the IgM molecule. We are also using the chemiluminescence technique (quite sensitive) to further identify the putative antigen. Concerning the Sydenham's caudate antigen we are screening sera from these patients both on a cDNA library of human caudate as well as immunoblots of human and mouse caudate specimens. In this respect we have identified two bands of 82 and 66 Kda that appear promising. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Dysregulation of apoptosis has been linked to several diseases such as cancer. Alzheimers disease and Huntinton's chorea. The process of apoptosis induces translation shutoff which is likely to be mediated by cleavage of certain initiation factors and phosphorylation of other regulatory factors, and which is also likely to be crucial for the completion of cellular killing. Studies will be performed in vitro in cell extracts or with purified recombinant proteins or in vitro in tissue culture cells to elucidate the various modifications which occur in translation regulatory factors and their specific effects on translation activity during apoptosis. Efforts will focus on eukaryotic translation initiation factor 4G (eIF4G) and poly(A)binding protein (PABP) which are crucial factors which control translation initiation rates and modulate 5'-3' interactions between mRNA ends. Preliminary evidence provided shows that both eIF4G and PABP are cleaved at the time during development of apoptosis when protein synthesis is being shutoff in the cells. Experiments will determine if cleavage destroys or modulates the ability of eIF4G and PABP to function in all or only some translation reactions and/or if 5'-3' interactions are disrupted. Further, we hypothesize that cap- independent translation of crucial regulatory proteins whose mRNAs contain internal ribosomal entry sites (IRES) will be capable of continued translation after cleavage of eIF4G. IRES control elements found on certain viral and cellular genes will be subcloned into various expression vectors and tested for translational efficiencies in vitro and in vivo under various conditions of apoptosis or factor-cleavage. The long term goal is to understand how events during apoptosis lead to cell death and further our basic understanding of how protein synthesis is regulated in human cells.

Project Title: METABOTROPIC RECEPTORS IN GLOBUS PALLIDUS Principal Investigator & Institution: Poisik, Olga; Division of Neuroscience; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2003; Project Start 14-DEC-2002 Summary: (provided by applicant): The primary objective of this project is to understand how metabotropic glutamate receptors (mGluRs) shape the output of the globus pallidus (GP), an intrinsic component of the basal ganglia, a group of subcortical nuclei that control motor behavior and also have cognitive functions. The activity of the GP is disrupted in some disorders of the basal ganglia such as Parkinson's disease, Hungtington's chorea, and depression. Activation of mGluRs results in important and long-lasting effects in many brain regions, which makes them attractive pharmacological targets in treating neurological disorders. The ultimate goal of this proposal is to collect the necessary information that is required to establish whether mGluRs in the GP can serve as therapeutic targets in treatment or management of neurological diseases that affect the GP output. More specifically, this work will examine the roles of mGluRs on: 1) the excitability of GP neurons, 2) the inhibitory synaptic transmission in the GP, and 3) on the desensitization mechanisms of some postsynaptic mGluRs in the GP. The functional roles of mGluRs and their desensitization mechanisms will be studied using in vitro electrophysiological

recordings in living rat brain slices. Commercially available agonists and antagonists to all groups of mGluRs will be utilized. We intend to study the desensitization mechanisms of mGluRs in the GP because some of these receptors are known to desensitize, which limits their usefulness as therapeutic targets in treatment or management of diseased states. Overall, this work will disclose the functions of mGluRs in the GP and their useful potential in treating basal ganglia disorders.

Project Title: MOLECULAR AND CELLULAR PHYSIOLOGY OF EPISODIC ATAXIA Principal Investigator & Institution: Maylie, James G.; Obstetrics and Gynecology; Oregon Health & Science University Portland, or 972393098 Timing: Fiscal Year 2003; Project Start 30-SEP-1998; Project End 30-NOV-2006 Summary: (provided by applicant): Episodic Ataxia / Myokymia Syndrome Type 1 (EA1) is an inherited autosomal dominant human neurological disorder. The principal symptoms of EA1 are myokymia and episodic attacks of generalized ataxia that are diminished by carbonic anhydrase inhibitors such as acetazolamide. EA1 is due to missense point mutations in KCNA1, the gene encoding the voltage-gated delayed rectifier potassium channel, Kv1.1; most mutations alter the biophysical properties of Kv1.1 channels. In the cerebellum, Kv1.1 is localized to axonal branch points and the pinceau synaptic structure of GABAergic interneurons that innervate the Purkinje cells. To understand the cellular consequences of EA1 mutations in Kv1.1 that result in ataxia, and the mechanism by which acetazolamide reduces the ataxia, ES cell-mediated homologous recombination was used to produce a transgenic mouse model of EA1 harboring the EA1 mutation V408A. In the EA1 mice, cerebellar Purkinje neurons show increased frequency and amplitude of spontaneous inhibitory postsynaptic currents (IPSCs). Two overall aspects will be investigated. First, the mouse model will be evaluated for EA1 using a battery of behavioral tests for motor coordination and the efficacy of acetazolamide. Second, the cellular basis of ataxia in EA1 mice will be examined using paired recordings from presynaptic basket cells and postsynaptic Purkinje cells in cerebellar slices, coupled with Ca2+ imaging. Four specific hypotheses will be tested: 1) Transgenic mice harboring the V408A allele provide an animal mode/for human EA1. 2) The increased frequency of spontaneous Purkinje cell IPSCs in EA1 mice results from reduced failure of action potential propagation at branch points along the basket cell axon. 3) The increased amplitude of Purkinje cell IPSCs in EA1 mice results from reduced failure of action potential propagation within the synaptic terminals of the basket cell, the pinceaus. 4) The higher GABAergic activity in EA1 basket cells predisposes the Purkinje cells to a transformation from a hyperpolarizing to depolarizing postsynaptic potential. Acetazolamide, by minimizing repair of the HCO3 gradient, reduces the depolarizing GABAA signal transformation, thus maintaining an inhibitory postsynaptic response to GABAA. These experiments will establish a link between altered electrophysiology and behavior in EA1 and demonstrate a precise connection between altered Kvl.1 channel biophysical function and the consequence of the altered channel function in neurons in rive. The use of transgenic technology to develop mouse models of disease will permit an understanding of EA1 and the possibility of new pharmacological treatments for this disease.

Project Title: MOLECULAR STUDIES OF BRAIN NMDA RECEPTORS Principal Investigator & Institution: Zukin, R Suzanne.; Professor; Neuroscience; Yeshiva University 500 W 185Th St New York, Ny 10033 Timing: Fiscal Year 2002; Project Start 01-JUL-1984; Project End 30-JUN-2004 Summary: The NMDA-type glutamate receptor is implicated in long-term potentiation, memory formation, brain development, and the neurodegeneration associated with epilepsy, ischemia, Huntington's chorea, Alzheimer's disease and AIDS encephalopathy. The proposed research aims to study molecular diversity in neuronal NMDA receptors. Molecular diversity will be addressed at the following levels of resolution; amino acid residues, receptor domains, receptor variants, individual cells, and neural circuits. Experiments outlined in this proposal are directed at the development of a detailed molecular/functional/anatomic profile of NMDA receptor variants. This laboratory has cloned two new NMDA receptor splice variants from rat brain and has characterized their functional properties. The receptor variants differ in their agonist affinity, current amplitudes, and regulation by polyamines, zinc and protein kinase C(PKC). In one project, we will use site-directed mutagenesis to identify functionally important amino acid residues in the NR1 receptor protein. Recombinant NMDA receptor channels will be analyzed in Xenopus oocytes and human embryonic kidney 293 cells by whole cell recording and by patch clamp. Studies will focus on the receptor domains involved in polyamine and zinc potentiation, regulation by PKC and in binding of glycine and glutamate. Working hypotheses are as follows: 1) Positively charged residues within the N terminal insert N1 govern zinc and spermine potentiation, agonist potency, and current amplitude, thereby generating receptors with altered normal responsiveness and sensitivity to glutamate pathogenicity; 2) In NR1 receptors lacking the C1 insert, serine residues within the cytoplasmic loops play a critical role in regulation by PKC; 3) A glycine receptor-like motif within the N terminal domain forms part of the glycine binding site. 4) A glutamate binding protein (QBP)-like domain within the N terminal domain of NR1, just preceding TMI, is involved in the glutamate binding site. In a second project we will characterize NR1 heteromers with normal, mutationally altered and chimeric NR2 receptors for comparison in a situ receptors and to determine structure/activity relationships for this receptor subunit. In a third project we will define cell-specific and circuit-specific expression of NMDA receptor splice variants in the hippocampus, a brain region known to be vulnerable to glutamate toxicity. Individual hippocampal neurons grown in dissociated culture on coverslips will be analyzed electrophysiologically at the whole cell and single channel level for sensitivity to polyamines and to PKC. Subpopulations of NMDA splice variants and subtypes will be identified by in situ hybridization using exon-specific and splice junction-specific oligonucleotide probes. As a future direction, individual neurons will be analyzed for expression of splice variants by patch clamp methods and by the polymerase chain reaction. Findings from these studies are expected to aid in the development of new strategies for intervention in neurodegenerative disorders.

Chorea
Summary: Rheumatic fever is a sequela of group A streptococcal infection primarily in children. Manifestations of the disease include carditis, arthritis and chorea. Our hypothesis is that autoimmune mechanisms due to molecular mimicry between the group A streptococcus and human tissues are responsible for the disease. Our data support this hypothesis. We have identified host and streptococcal antigens which react with anti-strep/heart antibodies and T cells, and we have identified streptococcal and human cardiac myosin epitopes which produce carditis and valvulitis in animal models of disease. Despite our progress, we do not know how these crossreactive autoantibodies function in the pathogenesis of acute rheumatic fever(ARF) or the exact nature and antigenic specificities of the T cells in rheumatic carditis. Therefore, the goal and objectives propose to answer questions about the potential role of antibody in disease and to investigate the nature of the T cells which are crossreactive and appear to be responsible for valvulitis. The objectives are 1) to produce a panel of cytotoxic/crossreactive monoclonal antibodies (mAbs) from humans and transgenic mice and passively transfer IgM and IgG mAbs to test for tissue deposition in vivo; 2) to determine the nucleotide sequences of crossreactive antibody V, D, and J region genes; 3) to produce transgenic mice containing the VDJ genes(H and L) of human and mouse crossreactive and/or cytotoxic mAbs; 4) to investigate the Lewis rat model of valvulitis by producing and characterizing T cell clones from rats immunized with rM6 protein and cardiac myosin and in passive transfer experiments determine if these T cells produce disease; 5) to compare valves immunohistochemically from rheumatic carditis and Lewis rat valvulitis to identify similarities. These studies will attempt to define the steps in the pathogenesis of rheumatic carditis and will continue to support the growing body of evidence that infectious agents play a role in the development of autoimmunity in man.

MECHANISMS--PROSPECTIVE
Principal Investigator & Institution: Leckman, James F.; Nieson Harris Professor; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2002 Summary: (Adapted from applicant's abstract): The long-term goal of this Project is to establish whether or not immunological alterations accompany an increase in clinical severity in patients with Tourette's syndrome (TS), obsessive-compulsive disorder (OCD), and attention deficit hyperactivity disorder (ADHD). It has been hypothesized that susceptible individuals develop symptoms of these disorders as a result of postinfectious autoimmune processes. Infections with group A beta-hemolytic streptococci are thought to initiate these processes. Two mechanisms have been proposed to explain the putative post-infectious autoimmunity: antigenic mimicry and superantigens (SAGs). We plan to explore each of these mechanisms by performing a prospective longitudinal study of children and adolescents at risk of symptom exacerbation. Based on pilot data reported in a Project, we plan to examine in an exploratory fashion the predictive value of rises in anticytoskeletal, antinuclear, and antineuronal antibodies for ensuing symptom exacerbations. Based on pilot data, we postulate that symptom exacerbations in susceptible individuals are associated with skewing of the T-cell receptor (TCR) V beta repertoire and changes in cytokine expression. In order to evaluate the SAG hypothesis, we will make repeated measures to determine the TCR V beta repertoire of CD4+ T cells and CD8+ T cells using flow cytometry. Patients with Sydenham's chorea are reported to have increased volumes of their basal ganglia. We

propose to collect serial magnetic resonance imaging scans to monitor basal ganglia volumes over the course of symptom exacerbation. Patients with autoimmune disorders often share specific HLA alleles within the histocompatability complex. As in a Project, we propose to now test whether a similar sharing of alleles exists. The DR and DQ alleles for all patients will be determined. In contrast to a Project, the HLA genotypes can be examined in relation to clinical and immunological phenotypes defined over the period of the prospective longitudinal study. Phenotypic data will be obtained by direct structured psychiatric interviews of all pertinent family members with respect to the occurrence of symptom exacerbations using expert interviewers trained by the Clinical Core. If specific immunological alterations are consistently associated with acute clinical exacerbations, then the exact nature of these alterations should provide insight as to the immunologic mechanisms involved. Most importantly, this knowledge may provide a basis for the rational design of therapeutic and preventative interventions, primarily in the form of antimicrobial prophylaxis, but possibly including plasmapheresis, IVIG therapy, and future vaccination.

Principal Investigator & Institution: Murphy, Tanya K.; Associate Professor; Psychiatry; University of Florida Gainesville, Fl 32611 Timing: Fiscal Year 2002; Project Start 15-FEB-2001; Project End 31-JAN-2006 Summary: This is a request for a Mentored Patient-Oriented Research Career Development Award. The purpose of this award is to support the supervised research experience coupled with critical didactic training to develop the skills necessary to become an independent investigator in the area of child neuroimmunology research. An example of a neuropsychiatric illness believed to have an autoimmune etiology is Sydenham's chorea (SC). An interplay of genetic, developmental, and environmental factors determines vulnerability to this complication of a streptococcal infection. It has been hypothesized that SC may be a medical model for some forms of tic and obsessive compulsive disorders (OCD). Evidence to support an autoimmune etiology in these and other child neuropsychiatric disorders has been increasing. It is an exciting area to explore as future developments may lead to additional diagnostic and treatment approaches to these disorders. The aim of the award is to promote career development in neuroimmunology of child neuropsychiatric disorders via didactic training in these areas and conducting a research plan under the mentorship of experts in OCD and Tourette's syndrome (TS) patient-oriented research, ileuroimmunology and related laboratory techniques, and pediatric infectious disease/immunology. This multidisciplinary training is necessary to foster skills in patient-oriented research in child neuropsychiatry and the translation from basic science skills needed to study mechanisms of disease. The proposed research study will test the following hypotheses: 1) Is there, evidence of immune dysfunction in children with OCD and/or chronic tic disorders (CTD)?;and 2) Is immune dysfunction more evident during symptom exacerbations? Exploring the role of immune responses in pediatric neuropsychiatry would provide the opportunity to fully develop skills in research design and methodology, patient characterization and neuroimmunology laboratory techniques. This award, along with support from the University Florida Brain Institute and the Department of Psychiatry, will enable the candidate to build a strong foundation of research skills needed to become an independent investigator.

Project Title: NEUROPROTECTION BY GROWTH FACTORS DURING NITRIC OXIDE TO Principal Investigator & Institution: Wagner, John A.; Professor; Neurology and Neuroscience; Weill Medical College of Cornell Univ New York, Ny 10021 Timing: Fiscal Year 2002; Project Start 01-MAR-1993; Project End 31-MAR-2004 Summary: Neurodegenerative disorders, whether caused by genetic defects, trauma, or other insults, result in long term deficits that seriously compromise the quality of life. The mechanisms that lead to neurodegeneration are complex, but recurrent themes suggest different types of neurodegenerative disorders may share common mechanisms. During the previous grant period, we made significant progress in developing two ideas: 1) that NO (nitric oxide) could be a major contributor to neuron death during ischemia, and 2) that growth factors and second messenger systems could modify the sensitivity of neurons to NO and ischemia. It is becoming increasingly clear that NO may play a central role in a number of neurodegenerative diseases, including Huntington's Chorea, Parkinson's Disease, and Amyotrophic Lateral Sclerosis. Signalling systems that minimize the damage caused by NO have the potential are potential therapeutic agents. This application focuses both on the mechanism of NOtoxicity and on neuroprotective mechanisms. It builds on several observations from the previous grant period. We want to determine signaling pathways controlled by growth factors are protective and which gene products make neurons more resistant to NOtoxicity. We are also interested in determining the toxic events that are controlled by NO that lead to cell death. The specific aims of this grant are: Specific Aim 1. To determine the roles of the ras/MAP kinase and the rac pathways in protection against NO toxicity. Specific Aim 2(a). To understand the toxic effects of cGMP on hippocampal neurons. Specific Aim 2(b). To determine the importance of a cascade of events, including the production of cGMP, the activation of cGMP-gated non-selective cation channels (cGGCC), and the activation of the cGMP-dependent protein kinase in the sensitivity of hippocampal neurons to NO-toxicity and ischemia. Specific Aim 3. To isolate genes that encode proteins which confer resistance to NO toxicity by using an expression-cloning approach. Our long range goals are to understand the role of NO in ischemia and neurodegenerative disorders, to understand how growth factors and other signaling molecules can protect neurons from the toxic effects of NO, and to translate these discoveries into therapy.

Project Title: NEW CYCLIZATION METHODS AND MULTICOMPONENT COUPLINGS Principal Investigator & Institution: Montgomery, John; Professor; Chemistry; Wayne State University 656 W. Kirby Detroit, Mi 48202 Timing: Fiscal Year 2002; Project Start 01-JAN-1998; Project End 31-DEC-2002 Summary: The primary significance of the proposed research is that potentiallypowerful new synthetic methods will be developed. The specific aims include the development of several new nickel-catalyzed procedures involving cyclizations and multicomponent couplings. Considerable attention will be devoted to the development of asymmetric and solid- phase procedures. The efforts in reaction discovery are designed to develop processes that rapidly construct complex organic substructures from simple, readily-available precursors in a predictable and efficient manner. The research will focus exclusively on the development of catalytic processes that should be amenable to scaleup in an environmentally-benign fashion. A new approach to alpha-

amino acid synthesis will be pursued which is unique that the amino acid side chain is derived from up to four components in a simple three-step operation. The rapid and flexible preparation of amino acids in the solid phase should provide a powerful combinatorial tool for small molecule drug discovery and polypeptide synthesis employing nonproteinogenic amino acids. A general synthetic approach to the allopumiliotoxin alkaloids will be developed, and a formal total synthesis of a representative member, allopumiliotoxin 339B, will be pursued. The pharmacological activity of the pumiliotoxins in linked to mechanisms involving facilitation of calcium influx into the muscle fiber and/or a facilitation of calcium release from the sarcoplasmic reticulum. The proposed synthetic route to the allopumiliotoxins should allow rapid construction of the central bicyclic skeleton with complete stereocontrol. A general approach to the kainoid amino acids will be developed, and an enantioselective total synthesis of (-)-kainic acid, the simplest member, will be pursued. Their potent neuroexcitatory activity has allowed the kainoids to serve as effective models for neuronal diseases such as epilepsy and Huntington's chorea and for neuronal cell loss in senile dementia. The proposed synthetic route to the kainoids will allow facile introduction of various C-4 side chains, which is the position at which all kainoids differ structurally. The concise and flexible routes proposed for the synthesis of allopumiliotoxin alkaloids and kainoid amino acids should allow the facile preparation of preparative quantities of the natural products as well as new derivatives for further pharmacological investigations.

Project Title: PANDAS AND STREP INFECTION: ARE THEY LINKED? Principal Investigator & Institution: Kurlan, Roger M.; Professor; Neurology; University of Rochester Orpa - Rc Box 270140 Rochester, Ny 14627 Timing: Fiscal Year 2002; Project Start 25-SEP-2001; Project End 31-JUL-2005 Summary: Sydenham's chorea is the only accepted immune-mediated central nervous system manifestation of group A beta hemolytic streptococcal (GABHS) infection. Several lines of evidence now suggest that there may be a spectrum of post-GABHS immune- mediated neurobehavioral sequelae termed "Pediatric Autoimmune Neuropsychiatric Disorders after Streptococcal Infection (PANDAS)". Tics, including Tourette's syndrome (TS), and obsessive-compulsive disorder (OCD) have been reported as the characteristic features of PANDAS. Proposed is a multicenter prospective case control cohort study involving 40 cases of PANDAS and 40 matched controls with TS and/or OCD but without evidence of PANDAS. All subjects will undergo intensive clinical and laboratory prospective observation for 24 months to determine whether antecedent GABHS infection is: 1) temporally associated with exacerbations of PANDAS, 2) specifically associated with exacerbations of tics and OCD, and 3) a specific trigger for exacerbations of PANDAS. All determinations of case/control status, GABHS infection and clinical exacerbation will be determined independently by blinded review in order to limit selection and clinical biases. Establishing a post-infectious etiology for PANDAS would dramatically change our understanding of the causes of TS and OCD, alter our therapeutic approach and may have a critical public health implication of preventing potentially fatal rheumatic cardiac sequelae in affected children. Disproving the PANDAS hypothesis would prevent the use of expensive and potentially dangerous therapies (e.g., plasma exchange, immune globulin, antibiotics) that have been proposed for PANDAS patients.

Chorea
Project Title: PATHOPHYSIOLOGY OF CHOREA Principal Investigator & Institution: Mink, Jonathan W.; Associate Professor; Neurology; University of Rochester Orpa - Rc Box 270140 Rochester, Ny 14627 Timing: Fiscal Year 2002; Project Start 19-JUN-2000; Project End 31-MAY-2005 Summary: Chorea is a movement disorder that results from basal ganglia injury due to a variety of causes in children. Chorea is characterized by sudden, brief, involuntary muscle contractions causing movements that appear to flow from body part to body part in an unpredictable manner. Disorders associated with chorea include CNS infections, post-infectious and other autoimmune diseases, ischemia during cardiopulmonary bypass, 'extrapyramidal' cerebral palsy, a variety of toxic and acute metabolic processes, degenerative conditions, and inborn errors of metabolism. In many cases the cause is unknown. In diseases with well defined neuropathology, chorea has been associated with abnormalities in the striatum (caudate and putamen) and the subthalamic nucleus (STN). However, the fundamental pathophysiology of chorea is not known. This is due in part to the lack of non-primate models and in part to the difficulty of measuring involuntary movements in the primate models that do exist. Current medical treatment options for chorea are few, may have significant side effects, and are often ineffective. The proposed experiments will develop quantitative 3dimensional kinematic measures of chorea and use them measure spatial and temporal properties of chorea in adults and children with different disorders. Focal pharmacologic manipulation of basal ganglia nuclei will be used in monkeys to produce chorea. The resulting chorea will be measured in the monkeys and compared to human chorea in order to validate the monkey models, especially with respect to childhood chorea. The monkey models will then be used to investigate the fundamental pathophysiology of chorea by recording the activity of individual globus pallidus internal segment neurons before and during chorea. Through a combination of neurophysiologic and kinematic techniques to study experimentally produced chorea, the prevailing hypotheses of chorea pathophysiology can be tested rigorously. There is strong potential to identify the fundamental mechanisms of chorea. Development of a non-invasive method to quantify chorea in children and in monkeys will be an important advance toward better characterization of the pathophysiology of involuntary movements and development of more effective medical therapies.

Project Title: ROLES OF GSH1 & 2 GENES IN TELENCEPHALIC NEUROGENESIS Principal Investigator & Institution: Campbell, Kenneth J.; Assistant Professor; Children's Hospital Med Ctr (Cincinnati) 3333 Burnet Ave Cincinnati, Oh 452293039 Timing: Fiscal Year 2002; Project Start 01-JUL-2002; Project End 30-APR-2007 Summary: (provided by applicant): The telencephalon represents the region of the brain most concerned with cognition and voluntary movement. Two of the major telencephalic regions controlling these processes are the cerebral cortex and the striatum (also known as the caudate-putamen). Malfunction of these regions occurs in a number neurodegenerative disorders such as Parkinson's disease and Huntington's chorea, leading to abnormal movements and in some cases dementia. Moreover, certain neurodevelopmental disorders, such as Schizophrenia, Tourette's syndrome and autism are believed to result from malfunction and/or altered development of the cerebral cortex and striatum. Thus understanding the development of these telencephalic brain regions is likely to be of considerable importance to the diagnosis and/or treatment of these disorders.Regional development along both the anterior/posterior and dorsal/ventral axes of the developing telencephalon is known to be controlled by the spatially and temporally restricted expression of developmental control genes. Many of these developmental control genes belong to the homeobox transcription factor subclass. Two such examples are the related genes Gsh1 and Gsh2, which encode for homeobox proteins and are required for normal development of distinct subregions in the telencephalon, diencephalon and hindbrain. Recent studies have demonstrated that Gsh2 is required for the normal development of the striatum and olfactory bulb. Homozygous loss-of-function mutants for Gsh2 possess a significantly smaller striatum and reduced numbers of olfactory bulb interneurons as compared to wild-type controls. These defects are caused by a misspecification of the striatal and olfactory bulb precursors in the Gsh2 mutants at early stages of neurogenesis. The striatal and olfactory bulb neurogenesis that does occur the Gsh2 mutants is likely due to the fact that the molecular specification of striatal projection neuron and olfactory bulb interneuron precursors normalizes at late stages of neurogenesis. Our recent results have shown that this delayed normalization depends on the function of Gsh1. Although Gsh1 homozygous mutants do not display obvious defects in striatal and olfactory bulb
24
Chorea
neurogenesis, this gene is essential for the development of these telencephalic regions in the Gsh2 mutant telencephalon.The experiments outlined in this proposal are aimed at better understanding the specific roles of Gshl and Gsh2 in the development of the striatum and olfactory bulb interneurons. Firstly, the role that Gsh genes play in retinoid metabolism and signaling will be studied using retinoid reporter assays as well as transgenic mice in which retinoid signaling has been blocked. Secondly, the functional equivalence of the GshI and Gsh2 will be tested in knock-in experiments where Gsh2 will be replaced with GshI using gene targeting as well as in embryonic transplantation studies using mutant cells. Finally, we will determine the spatial and temporal requirements for Gsh2 in striatal and olfactory bulb development using gene targeting and conditional mutagenesis.

Project Title: STRUCTURAL BASIS OF PP1 REGULATION BY SPINOPHILIN Principal Investigator & Institution: Page, Rebecca; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2002; Project Start 01-SEP-2000 Summary: The production of smooth, voluntary motions is a consequence of the rapid and precise processing of incoming sensory signals into outgoing motor responses. Much of this processing occurs within specialized cells of the striatum, medium spiny neurons (MSN), whose activity is regulated by the opposing actions of glutamate (excitatory), g-aminobutyric acid (inhibitory; GABA) and dopamine (modulatory) neurotransmitters. It is the integration of these signals in MSNs which leads to precise muscle control, and imbalances in these signaling pathways are characteristic of numerous motor disorders, including Huntington's chorea and Parkinson's disease. Studies have implicated a central role for the protein serine/threonine phosphatase (PSP) protein phosphatase-l (PP1) in MSN signal integration, as it is a target of both the glutamatergic and dopaminergic signaling pathways. A novel PP1 targeting/scaffolding protein, spinophilin, which localizes PP1 to dendritic spines, has recently been identified. In addition to binding PP1, spinophilin also binds actin filaments and D2 dopamine receptors. The presence of these independent domains within a single protein makes spinophilin uniquely structured to link the PP1 phosphatase signaling cascades to the proteins of the cytoskeleton and the ion channels of the synapse, thus providing a molecular basis for postsynaptic signal integration. Crystallographic studies of the individual spinophilin domains, both alone and complexed to their binding partners, will be carried out to elucidate the structural basis of PP1 localization and activity modulation by phosphatase targeting proteins. Structural information obtained from such a study could then be used to design drugs which function to disrupt the PP1:PP1targeting subunit interactions-drugs which may be potential therapies for the motor disorders of Huntington's chorea and Parkinson's disease.

Project Title: THE NEUROPHYSIOLOGY OF SHAPE AND SPATIAL WORKING MEMORY Principal Investigator & Institution: Sereno, Anne B.; Neurobiology and Anatomy; University of Texas Hlth Sci Ctr Houston Box 20036 Houston, Tx 77225 Timing: Fiscal Year 2002; Project Start 01-APR-2001; Project End 31-MAR-2006 Summary: adapted from applicant's abstract): This proposal examines two kinds of working memory-memory for shape and space- at the cellular level using a single unit recording technique in awake behaving rhesus monkeys. Much work suggests that perceptual processing proceeds along two cortical paths in temporal and parietal cortices, often characterized as the 'what' and where pathways, respectively. Both pathways project to regions of prefrontal cortex. Previous work has not been careful in the manipulation of featural and spatial working memory requirements and no study has compared cell response to both kinds of working memory within the same cortical area with identical visual conditions. Using the proposed paradigms, we have just finished recording from posterior parietal and inferior temporal cortices of animals performing these tasks where we found quite different patterns of findings. This study will provide valuable information as to whether working memory of shape and space are physiologically segregated in prefrontal cortex. We will also be able to report exactly how these types of working memory modulate cell response and how this relates to the sensory and motor response of the cell. Further, we will be able to compare the findings directly to data we have obtained from posterior parietal and inferior temporal cortices. Prefrontal cortex has been implicated in a variety of human neurological and mental diseases, including Parkinson's disease. Huntington's chorea, Korsakoff's disease, and schizophrenia. Little work in the neuropsvchology of memory has focused on shortterm or working memory. Characterization of mechanisms related to working memory in prefrontal cortex may prove useful for better understanding what role short-term or working memory deficits play in the cognitive and psychiatric abnormalities that are associated with these conditions.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.3 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with chorea, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “chorea” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for chorea (hyperlinks lead to article summaries): 3
PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND CHOREA Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and chorea.
Finding Nutrition Studies on Chorea The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.4 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “chorea” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 3. ALTERNATIVE MEDICINE AND CHOREA Overview In this chapter, we will begin by introducing you to official information sources on complementary and alternative medicine (CAM) relating to chorea. At the conclusion of this chapter, we will provide additional sources.
National Center for Complementary and Alternative Medicine The National Center for Complementary and Alternative Medicine (NCCAM) of the National Institutes of Health (http://nccam.nih.gov/) has created a link to the National Library of Medicine’s databases to facilitate research for articles that specifically relate to chorea and complementary medicine. To search the database, go to the following Web site: http://www.nlm.nih.gov/nccam/camonpubmed.html. Select “CAM on PubMed.” Enter “chorea” (or synonyms) into the search box.

CHAPTER 4. PATENTS ON CHOREA Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.5 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “chorea” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on chorea, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Chorea By performing a patent search focusing on chorea, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We

Chorea
will tell you how to obtain this information later in the chapter. The following is an example of the type of information that you can expect to obtain from a patent search on chorea: •
Fatty acid treatment Inventor(s): Vaddadi; Krishna S (Clayton, AU) Assignee(s): Scotia Holdings Plc (GB) Patent Number: 5,837,731 Date filed: September 26, 1996 Abstract: A method of treating Huntington's Chorea by the administration of effective amounts of GLA or DGLA and a method of delaying the onset of Huntington's Chorea or preventing it altogether by administering appropriate amounts of GLA or DGLA to clinically normal individuals who are genetic carriers of the disease, and a method of preparation of medications for such purpose using such acids. Excerpt(s): The invention relates to treatment of Huntington's Chorea (HC). The genetic basis for HC has been identified and tests are now available to identify those carriers who will at some time in the future become ill. Much is also known about the neuropathology. In the region of the brain area known as the striatum, specific neurons which employ acetyl choline or gamma-amino-butyric acid (GABA) as their transmitters degenerate. This is followed by widespread loss of neurons in other parts of the brain region known as the basal ganglia where the striatum is found, and also throughout the cerebral cortex. There are no specific treatments for the disease. Drugs which are used in schizophrenia and which interfere with dopamine receptor action may help to sedate psychiatric patients with HC and also reduce the abnormal movements. Most individuals with HC end up in specialised hospital or nursing units where they stay an average of around seven years before death occurs.

Method and composition for the treatment of apathy-amotivation syndrome Inventor(s): Kaminski; Ram (New York, NY) Assignee(s): The Mount Sinai School of Medicine of the City of New York (New York, NY) Patent Number: 5,453,428 Date filed: September 7, 1993 Abstract: In accordance with the present invention, neuropsychiatric symptoms of apathy-amotivation syndrome and particularly those symptoms in: Alzheimer's disease, multiple sclerosis, Huntington's chorea, frontal lobe lesions, and AIDS dementia can be ameliorated by treating a patient with a histamine H.sub.2 -antagonist that passes the blood-brain barrier. Suitable H.sub.2 -antagonists include famotidine and ranitidine. The H.sub.2 -antagonists may be co-administered with other compounds which are known to be useful in the treatment of the above neuropsychiatric conditions, and in one aspect of the invention can be formulated with such other compounds into a therapeutic composition. Excerpt(s): This application relates to a method and composition for use in the treatment of apathy-amotivation syndrome (also known as abulia or anergia syndrome) in
Patents 83
neuropsychiatric disorders. The syndrome of apathy is defined as absence of or decrease in motivation (Marin, Differential Diagnosis and Classification of Apathy, American Journal of Psychiatry 147: 22-30, Jan. 1990). Slowness of thinking and diminished ability to shift from one set of thinking to the other. This can occur in a variety of apparently unrelated neuropsychiatric disorders. Some of the most common conditions that result in apathy-amotivation syndrome are: schizophrenia, Parkinson's disease, Alzheimer's disease, multiple sclerosis, Huntington's chorea and frontal lobe lesions. (Marin, Apathy: A Neuropsychiatric Syndrome, Journal of Neuropsychiatry and Clinical Neurosciences, 3: 243-254, 1991). In each case apathy-amotivation is just one of a plurality of symptoms associated with the disease. In the past, treatments of other aspects of these conditions such as motor and sensory deficits, dementia, and depression have little or no benefit with respect to apathy-amotivation syndrome. There is large body of evidence that describe apathy-amotivation syndrome and its manifestation in neuropsychiatric disorders. (Starkstein, et al., Reliability, Validity, and Clinical Correlates of Apathy in Parkinson's Disease, Journal of Neuropsychiatry, Volume 4, Number 2, Spring 1992; Bozzola, et al., Personality Changes in Alzheimer's Disease, Arch Neurol, Volume 49, March 1992; Burns, et al., Clinical Assessment of Irritability, Aggression, and Apathy in Huntington and Alzheimer Disease, The Journal of Nervous and Mental Disease Vol. 178, No. 1; Mendez, et al., Neurobehavioral changes associated with caudate lesions, Neurology 39, Mar. 1989; Robinson, et al., Mood Disorders in Stroke Patients, Brain (1984); House, et al., Mood Disorders in the Year after First Stroke, British Journal of Psychiatry (1991); Benson, et al., Psychiatric Aspects of Neurological Disease, Personality Changes With Frontal and Temporal Lobe Lesions, Grune & Stratton, Inc., 1975; Cummings, Clinical Neuropsychiatry, Grune & Stratton, Inc., 1985; McHugh, et al., Psychiatric Aspects of Neurological Disease, Psychiatric Syndromes of Huntington's Chorea: A Clinical and Phenomenologic Study, Grune & Stratton, 1975; Caine, et al., Psychiatric Syndromes in Huntington's Disease, Am J Psychiatry 140:6, June 1983; Ho, et al., The Acquired Immunodeficiency Syndrome (AIDS) Dementia Complex, Annals of Internal Medicine, Volume III, Number 5, Sep. 1, 1989; Cohen, et al., Amantadine Treatment of Fatigue Associated With Multiple Sclerosis, Arch Neurol Vol. 46, Jun. 1989). The common scientific view is to ascribe apathy-amotivation to deficits in the function of the frontal lobes. (Hecaen, et al., Psychiatric Aspects of Neurological Disease, Disorders of Mental Functioning Related to Frontal Lobe Pathology, Grune & Stratton, 1975; Trimble, Psychopathology of Frontal Lobe Syndromes, Seminars in Neurology, Volume 10, No. 3, Sep. 1990; Strub, Frontal Lobe Syndrome in a Patient With Bilateral Globus Pallidus Lesions, Arch Neurol, Vol. 46, Sep. 1989). In recent years, studies have implicated other brain structures that may be involved in the production of the apathy-amotivation syndrome (e.g., striatum and hippocampal formation) (Wang, Neurobehavioral Changes Following Caudate Infarct: A Case Report with Literature Review, Chin Med J (Taipei), 1991; Hedreen, et al., Neuronol loss in layers V and VI of cerebral cortex in Huntington's disease, Neuroscience Letters, 133 (1991); Alvarez, et al., The role of histamine in the anterior hypothalamus and its functional interaction with the hippocampus on exploratory behavior in adult male rats, Behavioural Brain Research, 48: 127-33, 1992) but their specific contribution is yet to be elucidated.

Chorea
Patent Applications on Chorea As of December 2000, U.S. patent applications are open to public viewing.6 Applications are patent requests which have yet to be granted. (The process to achieve a patent can take several years.) The following patent applications have been filed since December 2000 relating to chorea: •
Method of treatment of huntington's chorea with a protein extractable from mammalian organs Inventor(s): Panerai, Alberto; (Milano, IT) Correspondence: Nixon & Vanderhye, PC; 1100 N Glebe Road; 8th Floor; Arlington; VA; 22201-4714; US Patent Application Number: 20030153511 Date filed: April 17, 2003 Abstract: A method of treatment of patients affected by Huntington's chorea comprising the administration of an effective amount of a 14 kDa protein extractable from mammalian organs, particularly mammalian liver. Excerpt(s): The present invention concerns a method of treatment of patients affected by Huntington's chorea comprising the administration of an effective amount of a 14 kDa protein extractable from mammalian organs, particularly mammalian liver. Huntington's chorea (incidence of about 6.4/100,000) is an autosomal dominant degenerative disorder characterized by paralysis and intellectual deterioration beginning in young age and rapidly causing death. As in the case of Alzheimer's disease, this pathology also shows accumulation of protein agglomerates (huntingtine) which presumably lead to neurodegeneration. Several biochemical and genetic factors seem to be involved in the pathogenesis of Huntington's chorea, which remains however to be still elucidated. The formation of huntingtine in the brain of affected patients seems to be anyhow one of the main causes of the neurodegenerative effects typical of this disease.

Excerpt(s): The mitochondria have an independent genetic system of DNA (mtDNA) and RNA and are therefore able to synthesise certain proteins on their own. Both genes of the cell nucleus and the mitochondrial genome code for the components of oxidative phosophorylation and the citrate cycle. A genetic defect of the mtDNA may therefore affect oxidative phosphorylation and the citrate cycle, respectively, and cause malfunctions. Such defects or malfunctions have been associated with the so-called mitochondrial diseases. Genetic defects of mtDNA may be the result of local mutation by which one base is replaced by another. Such point mutations are associated with neurogenetic myasthenia, ataxia and retinopathia pigmentosa, for example. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Summary: Numerous disorders affecting mood, memory, concentration, intellect, and personality arise from physical abnormalities in the brain and often require medical intervention. Psychiatric and psychological treatments may ease some symptoms and may help patients and their families adjust to the diseases and deficits caused by them. However, these treatments often overlook the underlying physical conditions. Consequently, appropriate treatments for some dementias require investigating and addressing the underlying illness or physical problem. As part of a home reference guide, this chapter describes physical conditions that produce mental symptoms. Topics include: Alzheimer's disease (symptoms, progression, diagnosis, medical treatment, care, family caregiver stress, possible causes, and stages); ways of dealing with dementia on a daily basis; other primary dementias (multi-infarct dementia, Huntington's chorea dementia, and Pick's disease dementia); other physical brain disorders (AIDS dementia and other infectious diseases); ways for families to obtain help and information on dementia; medical treatments and medical illnesses that commonly produce organic (physical) mental symptoms (brain tumors and cancer, nutritional deficiencies and toxins, liver disease, endocrine disorders, drug and alcohol use and withdrawal, and trauma); delirium; and financial and legal issues for families caring for patients with Alzheimer's disease or other dementias.

Contact: Available online from Merck and Company, Inc. (800) 819-9456. Website: www.merck.com/pubs/mmanual_home/contents.htm. Also available from your local book store. PRICE: $29.95 plus shipping. Summary: This chapter provides information on the symptoms, diagnosis, and treatment of various movement disorders, including tremors, cramps, myoclonus, hiccups, Tourette's syndrome, chorea, athetosis, Huntington's disease, dystonia, Parkinson's disease, progressive supranuclear palsy, Shy-Drager syndrome, and coordination disorders. Damage to or an abnormality of an area of the nervous system that regulates movement may cause a person to experience a movement disorder. A tremor is an involuntary, rhythmic, shaking movement that occurs when muscles repeatedly contract and relax. Types of tremors include action, resting, intention, essential, senile, and familial tremors. Although treatment is usually not needed for movement disorders, drugs may be helpful for some people. A cramp is a sudden, brief, usually painful contraction of a shortened muscle or group of muscles. Cramps are common in healthy people and do not need to be treated. Myoclonus causes a synchronous quick jerk of affected muscles. Antiseizure drugs may be used to treat severe cases of myoclonic jerks. Hiccups are repeated spasms of the diaphragm followed by quick, noisy closings of the glottis. They are caused when a stimulus triggers the nerves that contract the diaphragm. Most cures for hiccups require holding the breath to increase the amount of carbon dioxide in the blood. Stimulating the vagus nerve may also help. Tourette's syndrome is a hereditary disorder characterized by motor and vocal tics. Antipsychotic drugs may help suppress them. Chorea and athetosis are symptoms that can result from several different diseases, including Huntington's disease and Sydenham's disease. Drugs that block the action of dopamine may help control abnormal movements. Huntington's disease is an inherited disease characterized by abnormal movements and gradual loss of brain cells. There is no cure for Huntington's disease, but drugs may help relieve symptoms and control behavior. In people who have dystonia, muscles may freeze in the middle of an action. Dystonia seems to be caused by overactivity in several areas of the brain. Types of dystonia are idiopathic torsion dystonia, blepharospasm, torticollis, and spasmodic dysphonia. Treatment is limited. Drugs with anticholinergic properties may be helpful. Parkinson's disease is a progressive, degenerative disorder of the nervous system. Although the cause of nerve cell degeneration and dopamine loss is usually not known, Parkinson's disease is sometimes a very late complication of viral encephalitis or a complication of using certain drugs. Muscle stiffness develops in Parkinson's disease, and initiating a movement is difficult. Various drugs are used to treat this disease, including levodopa, bromocriptine, pergolide, selegiline, anticholinergics, antihistamines, antidepressants, propranolol, and amantadine. Progressive supranuclear palsy causes muscle rigidity, inability to roll the eyes upward, and weakness of the throat muscles. The cause is unknown, and there is no completely effective treatment. Shy-Drager syndrome causes malfunction and destruction of the autonomic nervous system. Treatment is the same as
90
Chorea
for Parkinson's disease but includes the drug fludrocortisone. Coordination disorders occur when the cerebellum is damaged. •

[email protected]. Website: www.singpub.com. PRICE: $325.00 plus shipping and handling. ISBN: 1565937287. Summary: This chapter, from a book on the clinical care of the professional voice, discusses neurologic disorders affecting the voice in performance. The complex functions necessary for normal voice function require coordinated interactions among multiple body systems. Neurologic dysfunction that impairs control of these interactions commonly causes voice dysfunction. The authors note that it is not unusual for voice disorders to be the presenting complaint in patients with neurologic disease. Topics include neurolaryngology, neuroanatomy and neurophysiology of phonation, neurological dysfunction and voice, vocal cord paralysis, dysarthria (imperfect articulation in speech), vocal tremor, Parkinson disease, postpolio syndrome, stuttering, myasthenia gravis, and other neurological conditions affecting voice performance, including amyotrophic lateral sclerosis, multiple sclerosis, Huntington's chorea, Gilles de la Tourette syndrome, cerebrovascular accident (stroke), quadriplegia, facial paralysis in singers and actors, headache, and dizziness. The authors conclude that familiarity with the latest concepts in neurolaryngology, clinical voice disorders, and a close working relationship between laryngologists and neurologists may optimize treatment. 5 figures. 31 references.

PRICE: $69.95 plus shipping and handling. ISBN: 0912423293. Summary: This section of a chapter on infectious disorders provides health professionals with information on the epidemiology, pathogenesis, clinical features, diagnosis, and treatment of rheumatic fever. The disease is a delayed, nonsuppurative sequela of a pharyngeal infection by group A streptococci. Although the tissues of patients who have rheumatic fever show little evidence of group A streptococci infection, there is epidemiologic evidence indirectly implicating the bacteria in the initiation of the disease. Clinical features of rheumatic fever include arthritis that affects several joints in quick succession for a short time, heart murmurs, cardiomegaly, congestive heart failure, and pericarditis. Rheumatic heart disease, the most severe sequelae of acute rheumatic fever, occurs 10 to 20 years after the original attack and is the major cause of acquired valvular disease. Other clinical features include chorea, subcutaneous nodules, and erythema marginatum. Although the diagnosis of rheumatic fever cannot be established readily by laboratory tests, helpful tests include serial chest radiographs, electrocardiograms, streptococcal antibody tests, and acute phase reactant tests. Most cases can be treated with antiinflammatory agents, usually aspirin. Oral prednisone may be used to treat carditis. Antibiotic therapy with penicillin should be initiated and maintained for at

least 10 days, whether or not signs of pharyngitis are present. Antibiotic prophylaxis with penicillin should start immediately after resolution of the acute episode and continue until the patient is a young adult. 1 figure, 1 table, and 16 references.

CHAPTER 7. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for chorea. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a nonprofit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with chorea. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/.
PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee. If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

Coffee Break: Tutorials for Biologists15 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.16 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.17 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
15 Adapted 16
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 17 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.
107
APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on chorea can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to chorea. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to chorea. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “chorea”:

You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on chorea. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits.

Chorea
Summary: This fact sheet from the National Organization for Rare Disorders presents comprehensive information on Huntington's Disease, an inherited progressively degenerative disorder of the nervous system. The various synonyms for the disease are listed. The general discussion covers symptoms, causes, the affected population, related disorders (e.g., Hallervorden-Spatz Disease, Olivopontocerebellar Atrophy, Syndenham's Chorea, Wilson's Disease, and Tourette Syndrome), standard therapies, and investigational therapies with contact information for the investigators. Treatments are symptomatic and supportive. Neuroplastic medications such as haloperidon can partially suppress the involuntary movements. Additional contacts and resources, including those for genetic information and genetic counseling, are listed. 26 references. The NIH Search Utility The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to chorea. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information.

By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with chorea.
Patient Resources
111
The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about chorea. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “chorea” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “chorea”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “chorea” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “chorea” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.18
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of
