Brief summary

OBJECTIVES: I. Investigate the pathobiology of Tourette syndrome and related disorders by measuring various compounds of interest in cerebrospinal fluid, plasma, and urine of patients with Tourette syndrome, obsessive compulsive disorder, and/or chronic tics. II. Determine the pattern of familial aggregation of Tourette syndrome and obsessive compulsive disorder by systematic assessment of all first-degree family members of patients selected for cerebrospinal fluid studies. III. Establish the neurochemical and neuropeptide profile associated with the range of expression of the putative Tourette gene expression in adult and adolescent patients.

Detailed description

PROTOCOL OUTLINE: All patients are screened with a complete physical and neurologic exam, and a semi-structured interview. Patients then receive a comprehensive assessment of systemic disease. Patients and first-degree family members also participate in a genetic study. Any patient who experiences an unusual exacerbation of symptoms or significant side effects is removed from the study.
