Summary

This study will use magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) of the brain to try to gain a better understanding of the disease process in Tourette s syndrome, a neuropsychiatric disorder characterized by motor and vocal tics. Tourette s syndrome is also associated with behavioral and emotional disturbances, including symptoms of attention deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD). MRI and MRS show chemical substances in the brain. Findings in normal volunteers will be compared with those of patients.

Healthy volunteers and patients with Tourette s syndrome 14 years of age and older may be eligible for this study. Volunteers will be screened with a medical history and physical and neurological examinations. Patients will be screened through NINDS protocol 93-N-0202.

Participants will undergo MRI and MRS. MRI uses a strong magnetic field and radio waves to visualize brain anatomy and chemistry. For this study, the subject lies on a stretcher, which is moved into a strong magnetic field (the MRI scanner). Earplugs are worn to muffle loud thumping noises caused by the electrical switching of the radio frequency circuits. During the study, the subject lies still during each scan, for 1 to 8 minutes at a time. Total scanning time varies from 20 minutes to 2 hours, with most examinations lasting between 45 and 90 minutes. The subject can speak through an intercom with the staff member performing the study at all times during the procedure. Up to 5 studies may be performed.
