NCT ID: NCT00047944 Completed - Anxiety Disorders Clinical Trials

MRI Study of Brain Activity and Risk for Depression in Adolescents

Start date: October 12, 2002
Phase: N/A
Study type: Observational

Anxiety in children of parents with major depressive disorder (MDD) poses a particularly high risk for later-life MDD. In adults, MDD involves dysfunction in prefrontal brain regions that regulate attention to emotional stimuli. These abnormalities: i) have been found primarily in adults with specific familial forms of MDD; ii) persist after recovery from MDD, and iii) relate to anxiety. These findings raise the possibility that risk for MDD is tied to dysfunction in prefrontal regions involved in regulation of emotion, which possibly manifests as early-life anxiety. If this possibility were confirmed in never-depressed adolescents at high risk for MDD, the findings would provide key insights into the developmental neurobiology of MDD. The goal of this protocol is to study the neural substrate of risk for MDD in young people. This protocol tests the hypothesis that adolescents at high risk for MDD by virtue of childhood anxiety and parental history of MDD exhibit dysfunction in prefrontal cortex and amygdala, regions involved in emotion regulation. This goal will be accomplished through fMRI studies of emotion regulation in high and low-risk adolescents. For this research, at-risk adolescents will be recruited from participants in an NIMH-funded extramural study at New York University (NYU) examining the biology of risk for anxiety and depressive disorders. Over a three-year period, 45 high-risk probands and 60 low-risk comparisons will be studied, including 20 comparisons from the NYU sample and 40 from the Washington DC metropolitan area. In the present protocol, to be conducted at NIH, subjects will undergo volumetric MRI scans to assess structural abnormalities in the prefrontal cortex and medial temporal lobe. They will complete a series of four out-of-scanner cognitive tasks and two fMRI-based cognitive tasks that measure modulation of attention to emotional stimuli. The fMRI tasks are hypothesized to differentially engage the prefrontal cortex and amygdala in low vs. high risk subjects. These tasks will be used to test the hypothesis that at-risk individuals exhibit enhanced amygdala and reduced prefrontal activation on the fMRI emotion/attention tasks.

NCT ID: NCT00046020 Completed - Clinical trials for Depressive Disorder, Major

Study Evaluating Venlafaxine ER in Recurrent Depression

NCT ID: NCT00044681 Completed - Depression Clinical Trials

A Study of the Effectiveness and Safety of Risperidone to Augment SSRI Therapy in Patients With Treatment-resistant Depression

Start date: October 2002
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate the effectiveness and safety of risperidone to augment SSRI therapy in patients with treatment-resistant depression and to demonstrate the long-term maintenance effect of risperidone as augmentation therapy compared with placebo augmentation in these patients.

NCT ID: NCT00042575 Completed - Clinical trials for Major Depressive Disorder

Dose Escalation, Double-Blind Treatment With Duloxetine Hydrochloride Once Daily Dosing for Evaluation of Safety in Major Depression

Start date: June 2002
Phase: Phase 3
Study type: Interventional

The Purposes of this Study are to determine: The safety of duloxetine and any side effects that might be associated with it. Whether duloxetine can help patients with major depression. It is possible that information collected during this study will be analyzed by the sponsor in the future to evaluate duloxetine for other possible uses or for other medical or scientific purposes other than those currently proposed. Duloxetine might not have any good effects for you.
