Brain Function in Mentally Ill Adolescents

NCT00025857 · View on ClinicalTrials.gov ↗

Study Summary

The purpose of this study is to use brain imaging technology to examine the brain activity of adolescents with post-traumatic stress disorder (PTSD) and/or major depressive disorder (MDD) before and after treatment. Adults with PTSD or MDD exhibit abnormalities in the structure and function of certain parts of the brain. Although PTSD and MDD are psychiatric disorders that often emerge in childhood, the relationship between these disorders and brain structures has not been thoroughly studied in adolescents with the disorders. This study will use functional magnetic resonance imaging (fMRI) to study the parts of the brain that are involved in PTSD and MDD in adolescents. Adolescents with PTSD and/or MDD will be enrolled along with healthy adolescents with or without a history of abuse. Healthy adults will also be enrolled. Participants will be screened with a physical examination; blood tests; and interviews about mood, general degree of nervousness, and behavior. Adolescents and their parents will be interviewed separately and together. Following the interviews, participants will undergo psychological tests. Participants with PTSD and/or MDD will have two weekly sessions of talk therapy. Participants who continue to experience PTSD or MDD symptoms after the talk therapy may continue the talk therapy alone, begin treatment with fluoxetine (Prozac ) alone, or begin fluoxetine in addition to the talk therapy. Participants who take fluoxetine will have blood collected before treatment and 8 weeks after treatment has begun. If participants do not respond to the treatment, the treatment will be stopped and the participants will be offered another treatment. Participants who respond to treatment will continue treatment at NIH until a referral to an outside physician is made. Depending on the experiment in which they are enrolled, participants will undergo one or four MRI scans. Participants who will have four MRI scans will undergo the scans on separate days. During the

What the Registry Record Tells You About NCT00025857

The ClinicalTrials.gov registry entry for NCT00025857 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 105 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 3 conditions, with Healthy 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: NCT00025857 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.
