About this study

Official title: Adolescent Medial Temporal Lobe Function in Health and Illness

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 MRI, participants will complete tasks on a computer. Saliva samples will be collected before and after the scans. Participants with PTSD and/or MDD will collect their saliva one or two days before the MRI scan.

Read the detailed description

Adults with post-traumatic stress disorder (PTSD) or major depressive disorder (MDD) exhibit abnormalities in the structure and function of the amygdala and hippocampus (temporal lobe), as well as in the prefrontal cortex (PFC) and striatum (four brain structures underlying the emotional processing and reward systems). However, while these psychiatric disorders often emerge in childhood, the integrity of these neural structures has been minimally studied in psychiatrically impaired children and adolescents. In the current proposal, functional MRI (fMRI) will be used to evaluate the amygdala, hippocampus, PFC and striatum in (1) psychiatrically healthy adolescents; (2) adolescents with trauma history and PTSD or anxiety symptoms; (3) adolescents with trauma history, symptoms of depression and either PTSD or anxiety symptoms; and (4) adolescents with only major depressive or PTSD/anxiety symptoms; (5) adolescents with trauma and no trauma related symptoms. The proposed study is conducted in three separate experiments.

At this stage of the protocol, we completed experiment 1, and a pilot study to help guide experiments 2 and 3. In Experiment 1, we determined whether a fear conditioning paradigm elicited amygdala activity in healthy adolescents. The pilot study examined test-retest reliability of the fMRI signal in healthy adolescents and adults.

In Experiment 2, we will examine the functioning of the amygdala, hippocampus, PFC and striatum in healthy adolescents and those with the psychiatric conditions described above. During image acquisition, four cognitive tasks, targeting these regions, will be used: 1) a social interaction task, 2) an inhibition task (the Stop task or the antisaccade task), 3) an emotional rating/explicit memory task and 4) a probe detection task. One hundred twenty five participants (25 in five groups) will be recruited in experiment 2.

Experiment 3 will address the same question as in experiment 2 in relation to treatment response. In other words, in contrast to experiment 2, patients will be studied prior and after treatment of the psychopathology associated with their traumatic experience. The sample will include 125 patients (25 in each of the 4 groups) and 25 controls.

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy and Posttraumatic Stress Disorder, run by National Institute of Mental Health (NIMH) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00025857, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Dec 2019.
