Active clinical trials for "Depressive Disorder, Major"

The purpose of this study is to determine the clinical effects (if any) of connectivity-guided repetitive transcranial magnetic stimulation (rTMS) in the treatment of major depressive disorder (MDD) to provide clues about the ideal neural networks to target for more robust clinical outcomes, and to identify potential biomarkers of treatment response including changes in brain network connectivity.

This study is designed to evaluate the safety and preliminary efficacy of synchronized transcranial magnetic stimulation (sTMS) using the NeoSync EEG Synchronized TMS device (NEST) in subjects with Bipolar Disorder type I in a Major Depressive Episode. This is an open label study in which subjects will receive treatment 5 days per week for 6 weeks.

The purpose of this study is to evaluate the safety and effectiveness of acute NeuroStar TMS therapy in women who have postpartum depression.

This is a three-center, randomized, double-blind, fixed dose study designed to assess the efficacy, safety, and tolerability of a switch to vilazodone for sexual dysfunction associated with use of a selective serotonin reuptake inhibitor (SSRI) and serotonin-norepinephrine reuptake inhibitor (SNRI)compared to switching to sertraline in patients with Major Depressive Disorder (MDD). Vilazodone is a newly introduced, FDA approved antidepressant that is a combined serotonin specific reuptake inhibitor and serotonin 1A receptor partial agonist. In contrast to the SSRIs and SNRIs, appears to have low adverse effects on sexual functioning when compared to placebo.

The purpose of this study is to investigate the use of repetitive transcranial magnetic stimulation (rTMS) in helping to prevent relapse in major depressive disorder. rTMS is known to be an effective treatment for major depressive disorder, but there is also evidence that it may be effective in the maintenance of remission following treatment. However, it is not yet clear what maintenance strategy will yield the best outcome in preventing relapse. In this study, eligible patients who have finished one full course of rTMS for treatment of major depression will be randomized into three groups: (i) cluster rTMS, (ii) taper rTMS, and (iii) treatment as usual. The 'cluster rTMS' group will receive two weeks to daily rTMS six months after the completion of their regular rTMS treatment, the 'taper rTMS' group will receive three sessions a week for two weeks followed by two sessions a week for two weeks immediately following their regular rTMS treatment, while the 'treatment as usual' group will receive standard follow-up care from their own psychiatrist and/or primary care doctor. The investigators hypothesize that the group with cluster treatment will show significantly lower relapse rates in depressive symptoms as compared to the other groups.

The hypothesis of this study is that symptoms of anxiety, depression and insomnia; and indices of psychosocial function will all improve, while BZ use will decrease significantly during a twelve-week trial period of substituting quetiapine for benzodiazepines.

This research proposal aims to better understand the neurobiology of depression in adolescents and how repetitive transcranial magnetic stimulation (rTMS) may therapeutically impact brain function and mood. This study will be the first to use a randomized, double-blinded, sham-controlled approach to the investigation of rTMS therapy for depressed adolescents. This approach will allow for the validation of rTMS treatment outcomes in the depressed adolescent population in a scientifically rigorous manner. The magnetic resonance (MR) spectroscopy pattern of rTMS response will be analyzed according to previously established protocols.

We are doing this research study to find out if people who get better while taking a specific kind of antidepressant medication (a selective serotonin reuptake inhibitor, or SSRI) and people who get better while taking placebo (an inactive substance) have similar chemicals in their brains. Some participants may complete a procedure called Acute Tryptophan Depletion (ATD), which is a way to study the role of serotonin in depression. Some participants may also undergo a magnetic resonance-positron emission tomography (MR-PET) scan.

The primary objectives of the study are to test whether brain Mono Amine Oxidase-A (MAO-A) levels are elevated in patients with treatment-resistant major depression, and to explore whether MAO-A brain levels predict treatment outcome with Mono Amine Oxidase Inhibitor (MAOI) medication in this population.

GW856553 is a novel compound, currently in development for the treatment of Major Depressive Disorder (MDD), and other indications. GW856553 inhibits a protein which is responsible for the production of some pro-inflammatory molecules, called cytokines. Increased blood levels of these molecules were seen in populations of MDD patients and this was more apparent in subjects with severe symptoms, psychomotor retardation and loss of energy. Aim of the present study is to assess whether GW856553, by inactivating this protein, is able to suppress the production of the cytokines, and ultimately relieving depression symptoms. In this study GW856553 or placebo is given to MDD patients 7.5md twice daily for 6 weeks.
