Study Summary
This study will use brain imaging to map brain cell receptors for a chemical called GABA, a chemical that inhibits the activities of nerve cells. The study includes patients with succinic semialdehyde dehydrogenase deficiency, or SSADH (a disorder in which an enzyme deficiency disrupts GABA metabolism), their parents, and healthy volunteers. SSADH deficiency causes various neurological and neuromuscular problems, including mild to severe mental retardation, delays in the acquisition of skills requiring the coordination of mental and physical activities (psychomotor retardation), delays in language and speech development, and other symptoms. Healthy volunteers 18-55 years of age, patients with SSADH between 5 and 24 years of age, and parents of patients 18-55 years of age may be eligible for this study. Participants undergo magnetic resonance imaging (MRI) and positron emission tomography (PET) scanning as follows: Magnetic resonance imaging MRI uses a magnetic field and radio waves to produce images of body tissues and organs. For this procedure, the subject lies on a table that is moved into the scanner (a narrow metal cylinder surrounded by a magnetic field) wearing earplugs to muffle loud knocking and thumping sounds that occur during the scanning process. Scanning time varies from 20 minutes to 3 hours, with most scans lasting between 45 and 90 minutes. Participants may be asked to lie still for up to 90 minutes at a time. In addition to standard MRI, participants may also have new types of MRI that may detect brain abnormalities when regular MRI is normal, such as diffusion tensor MRI and magnetic resonance spectroscopy. There are no noticeable differences from ordinary MRI scans. Positron Emission Tomography A catheter (plastic tube) is placed in a vein in the subject's wrist. The subject lies on a table with his or her head placed in the scanner. A mask, used to help keep the head still in the scanner, is placed over the head. The mask is not uncomforta
