Filter by:This trial will test the safety and efficacy of a rTMS device for the treatment of major depressive disorder (MDD). It is hypothesized that rTMS will have an antidepressant effect. It is a 10-week, randomized, sham-controlled, multicenter trial in outpatients recruited in both academic and private research centers. It is comprised of three major phases: pre-study screening, acute treatment, and post-treatment taper. Eligible patients will be randomized to one of two rTMS treatment groups. One group will receive active rTMS treatment and one will receive an inactive, or sham, treatment. Each treatment takes about 45 minutes and is done on an outpatient basis. All trial related medical care is provided at no cost to the participant.
This is a placebo-controlled, fixed dose study that will evaluate the efficacy and safety of GW679769 in subjects with major depressive disorder.
The purpose of this study is to determine the safety and effectiveness of s-adenosyl-l-methionine (SAMe) in treating major depression.
The main objective of this research project is to describe the impact of depression on adolescent and family functioning compared to that of healthy adolescents and to understand the impact of Feedback and Patient Activation (FPA) on teen and family decision-making regarding seeking care for depressive disorders.
This study will investigate how the brain process emotions in healthy people and in patients who have major depression in order to better understand the causes of depression. It will examine what happens in the brain when a person responds to words related to different emotions while the brain's ability to manufacture a chemical called serotonin is reduced. Serotonin regulates functions such as emotion, anxiety and sleep, and stress hormones such as cortisol. In this study, participants' serotonin levels are reduced by depleting tryptophan, an amino acid that is the main building block for serotonin. Healthy volunteers and patients with major depression that has been in remission for at least 3 months may be eligible for this study. Candidates must be between 18 and 50 years of age and right-handed. They are interviewed about their medical and psychiatric history, current emotional state and sleep pattern, and family history of psychiatric disorders. Screening also includes psychiatric interviews and rating scales, neuropsychological tests, physical examination, electrocardiogram (EKG), and blood, urine, and saliva tests. Women have their menstrual phase determined by a blood test and home urine ovulation test kit. The study involves two clinic visits in which participants undergo tryptophan depletion and magnetic resonance imaging (MRI). Subjects arrive at the NIH Clinical Center in the morning after fasting overnight. They fill out questionnaires have a blood sample drawn, and then take 74 capsules that contain a mixture of amino acids found in the diet. At one visit they are given capsules that contain a balanced mixture of amino acids one would normally eat in a day; at the other visit, some of the capsules contain lactose instead of tryptophan, causing tryptophan depletion. At 2 p.m. participants fill out the same questionnaires they completed at the beginning of the day and have another blood sample drawn. Then they do a computerized test in the MRI scanner. MRI uses a magnet and radio waves to obtain pictures of the brain. For the test, subjects lie on a narrow bed that slides into the cylindrical MRI scanner. They are asked to press a button in response to words associated with different emotions that appear on a screen. Arterial spin labeling - a test that uses magnetism to measure blood flow in different areas of the brain-is also done during the procedure. After the scan, subjects eat a meal and then return home. DNA from the participants' blood samples is also examined to try to better understand the genetic causes of depression. Some of the white cells from the samples may also be grown in the laboratory so that additional studies can be done later. ...
The purpose of this study is to examine the effectiveness of ethyl-eicosapentanoic acid (ethyl-EPA), an omega-3 fatty acid, in treating depression.
Depression is a debilitating illness affecting large numbers of young people. In this study, children and adolescents ages 10 to 17 meeting criteria for clinical depression will participate in a 15-session group therapy (cognitive behavioral therapy or CBT) that teaches strategies for overcoming depressed mood. For half the participants, their parents will also participate in a parent group. By studying the role of parental involvement, we hope to develop more effective treatments for depressed children and teens in the future.
This trial is a 14 week, randomized, double-blind, placebo controlled study, to assess the safety and efficacy of aripiprazole as adjunctive treatment to an ongoing antidepressant treatment in patients with Major Depressive Disorder.

This trial is a 52-week safety study to evaluate the safety of adjunctive aripiprazole in outpatients with major depressive disorder who have experienced an incomplete response to an ongoing antidepressant trial.
