Official title
Functional MRI Study of Brain Mechanism Mediating Anhedonia in Major Depression
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will use magnetic resonance imaging (MRI) to examine how the brain regulates emotions in healthy people and in patients who have major depression and anhedonia (loss of feeling of pleasure in things that normally give pleasure). Healthy normal volunteers and patients between 18 and 50 years of age with major depression, with or without significant anhedonia, are eligible for this study. Candidates will be screened with a psychiatric interview, a physical examination that will include blood and urine samples, and an electrocardiogram, and a questionnaire about their emotions. Participants will perform a monetary reward task while lying in an MRI scanner. The task is similar to playing a computer video game with the possibility of winning cash. The amount of cash is largely dependent on the subject's performance. The accumulated amount of cash earned in a session will fluctuate depending on the subject's continuing performance level. That is, during a single session, a subject could lose money earned early in the session if his or her performance later in the session is not as good as earlier. MRI pictures will be taken during performance of the task. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. The patient lies on a table that is moved into the scanner (a narrow cylinder) and wears earplugs to muffle loud knocking and thumping sounds that occur during the scanning process. The procedure will last about 1 to 1-1/2 hours.
