Study Summary
This study will compare serotonin transporters in patients with obsessive-compulsive disorder (OCD) and healthy volunteers in order to better understand the role of serotonin in OCD. Serotonin is a chemical in the brain that transmits nerve impulses. The serotonin transporter (SERT) is a protein that regulates serotonin levels in the brain. Normal, healthy volunteers and patients with OCD between 18 and 50 years of age and in overall good health may be eligible for this study. Candidates are screened with a medical history, physical examination, blood and urine tests, and a psychological interview and tests related to OCD symptoms. Participants undergo the following tests: * Positron emission tomography (PET) scanning: For this test, subjects lie on the scanner bed, wearing special masks that are fitted to their heads and attached to the beds to help keep their heads still during the procedure. An 8-minute "transmission" scan is done to provide measures of the brain that will help calculate information obtained from subsequent scans. Then, a radioactive tracer is injected into a catheter (plastic tube) placed in the arm. The scan produces images of the serotonin transporters in the brain. Pictures are taken for about 2 hours, while the subject lies still on the scanner bed. * Magnetic resonance imaging (MRI) scanning: An MRI scan of the brain is done within 1 year of the PET scan-that is, up to 1 year before or 1 year after the PET scan. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. For this procedure, the patient lies on a table that is moved into the scanner (a narrow cylinder), wearing earplugs to muffle loud knocking and thumping sounds that occur during the scanning process. The procedure lasts about 1 hour, during which the patient will be asked to lie still for up to a few minutes at a time. * Genotyping: Subjects provide a blood sample (4 tablespoons) for DNA testing to look for genes or gene regions that may contr
