Active clinical trials for "Depressive Disorder, Major"

This study is evaluating the effects of two brain training exercises on: memory, cognitive processing and depression symptoms.

In this study, the investigators will be examining the effects of the deep repetitive transcranial magnetic stimulation (rTMS) using the H1 coil in patients over the age of 60 who have been unable to tolerate or failed to respond to antidepressant medications. The coil was designed to stimulate deeper regions of the left DLPFC. The investigators propose that active stimulation with the H1 coil will result in higher remission rates than placebo stimulation but will have a similar tolerability and safety profile.

Transcranial electrical stimulation (TES) techniques offer a novel treatment approach for depression and have shown promising efficacy. However, there is no published data to date on their effectiveness as a maintenance treatment. This study will investigate ways of using TES as a maintenance treatment to prevent relapse in depression.

The aim of this study was to evaluate the effect of sevoflurane or ketamine on the QTc and Tp-e interval during in patients with major depression.

Studies of the neural mechanisms underlying placebo effects in antidepressant clinical trials largely have been limited to demonstrating objective differences in brain activity between responders and non-responders to placebo. This 8 week Placebo-controlled and Open groups study employs a novel antidepressant trial design with integrated functional magnetic resonance imaging (fMRI) to manipulate patient expectancy and examine its neural mediators.

Major depressive disorder (MDD) is predicted to be the second leading cause of disability worldwide by the year 2020. The economic burden of depression in the United States is significant: $83.1 billion in 2000 and increasing. Much of this burden comes from the high rate of sub-optimal treatment outcomes associated with the disorder. Indeed, only 50% of MDD patients recover in less than 12 weeks with adequate treatment, and up to 20% of patients will fail to adequately respond to all currently available interventions. Moreover, current treatments come at the cost of significant central nervous system (CNS) side effects, further highlighting the need for more effective treatments with fewer side effects. This study will compare temperature ranges from the investigators preliminary studies involving thermoafferent pathways resulting in antidepressant actions with lower temperature ranges not expected to activate these pathways as a control condition, with the goal to evaluate whether previous observations were related to the temperature range in question or can be achieved with other levels.

This study will examine the effects of a first-line treatment for major depressive disorder (MDD), interpersonal psychotherapy (IPT), among men and women prisoners.

The purpose of this study is to evaluate the clinical effectiveness of acupuncture treatment on residual insomnia in major depressive patients.

The purpose of this research study is to learn whether specific types of brain imaging and psychological testing can predict how much benefit patients with depression will receive from a well-studied psychotherapy for depression, called cognitive behavioral therapy (CBT), and how the brain imaging and psychological tests change with treatment. We will also be comparing brain scans from this study between individuals suffering from depression and volunteers without depression. This study offers 14 sessions of one-on-one cognitive-behavioral therapy (CBT) over twelve weeks, administered by an experienced doctoral-level psychologist or psychiatrist.

The investigators will investigate in a sham controlled staggered onset design antidepressant effects and safety of deep brain stimulation (DBS) to the superolateral branch of the main medial forebrain bundle (slMFB).
