Brain Regulation of Emotions in People With Depression and Anhedonia
NCT00059579 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00059579
The ClinicalTrials.gov registry entry for NCT00059579 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 163 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Mental Health (NIMH), which has 317 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Major Depressive Disorder appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00059579 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
