View clinical trials related to Major Depressive Disorder.
Filter by:Patients suffering from Major Depressive Disorder with Psychotic features who have received no changes in their medications in the previous two weeks will receive "usual" treatment of antidepressants, antipsychotics and/or mood stabilizers and adjunct therapy using ORG34517. The patient will be hospitalized for up to two weeks to monitor their medications and progress and will return to the site for periodic assessments.
The purpose of this research is to determine if pregnenolone supplement is associated with a reduction in substance use and craving in patients with recurrent major depressive disorder or bipolar disorder and substance abuse/dependence. This research also wants to explore if pregnenolone supplements are associated with improvement in psychiatric symptoms and memory, which are often negatively affected in these patients. It is hypothesized that patients receiving pregnenolone supplements would show greater improvements in mood symptoms and memory, and crave substances less than the patients receiving placebo.
Low heart rate variability is a marker of increased risk of cardiac mortality, and is observed in depressed coronary artery disease patients. Some antidepressants may themselves, however, decrease heart rate variability. We will test the hypothesis that greater reduction in heart rate variability will be associated with duloxetine (which has noradrenergic activity) than escitalopram (a selective serotonin reuptake inhibitor). We will also test the hypothesis that changes in heart rate variability are related to the magnitude of norepinephrine transporter occupancy.
This study will characterize the mental health consequences of early-life trauma.
The purpose of this study is to evaluate alterations in sympathetic tone in patients with major depression with and without ischemic heart disease and then to reevaluate these patients after 8 treatments with electroconvulsive therapy(ECT). We expect to support the hypothesis that HRV are pathophysiologically associated with the state of major depression. We hypothesize the following: 1. Heart rate variability (HRV) will be decreased prior to treatment of depression in comparison to post-treatment measures of HRV. 2. After 8 treatments with ECT, HRV will be increased under basal conditions.
The primary objective of this project is to determine whether treatment with the SSRI, fluoxetine versus placebo reverses alterations in the central CRF system induced by early life stress experiences (i.e. childhood sexual and/or physical abuse) in cases with and without major depression. We also evaluate whether neuroendocrine changes after SSRI treatment correlate with clinical improvement.
It is hypothesized that the use of aripiprazole (Abilify) in patients with alcohol and/or drug dependence with comorbid psychiatric conditions will lead to: - Reduction in the amount of alcohol and/or drugs used as measured by the Time Line Follow Back (TLFB) and the Addiction Severity Index (ASI) - Reduction in cravings for alcohol and drugs as measured by the Penn Alcohol Craving Scale - Reduction in symptoms of co-morbid psychiatric disorders compared to before starting aripiprazole.
The purpose of the study is to evaluate the effects of a single-dose of Wellbutrin XL (bupropion hydrochloride) on reward processing.
The purpose of this project is to use behavioral techniques to investigate emotional processing in subjects with major depression and healthy comparison subjects.
A multicentre, randomised, open label study of out-patients with major depression who have failed to respond adequately to antidepressant treatment for their current episode of depression. The study compares outcomes associated with two methods of switching from current antidepressant to duloxetine
