View clinical trials related to Depressive Disorder, Major.
Filter by:This is a two-arm double-blind prospective randomized controlled trial (RCT) to evaluate clinical impact of pharmacogenomic testing on the treatment of major depressive disorder. Participants will be randomly assigned to two groups: pharmacogenomic-guided therapy group (guided group) and treatment as usual group (TAU group). The primary hypothesis is the pharmacogenomic-guided treatment group will demonstrate significantly higher percent improvement in depression score compared to treatment-as-usual group.
Efficacy of Cranial Electrotherapy Stimulation (CES) for the treatment of Major Depressive Disorder
The investigators are doing this research study to find out if using aspirin along with antidepressant treatment can lessen symptoms of depression. This study also aims to find out if some people improve more from taking aspirin than others. The investigators also want to see if it is possible to predict which participants will do better based on a blood test. Aspirin is approved by the U.S. Food and Drug Administration (FDA) as an over-the-counter pain medication. But, aspirin is not approved by the FDA to make antidepressant treatment better. This research study will compare aspirin to placebo.
This study aims to evaluate a technology-based treatment support system for patients undergoing the treatment of depression. The investigators will explore the usefulness of the technology-based treatment support system as an adjunct to psychotherapy for depression.
For a number of reasons women with major depressive disorder often discontinue conventional antidepressants when they become pregnant and prefer not to take them when depressive illness develops in the course of pregnancy. There is now considerable evidence that the administration of the omega-3 polyunsaturated fatty acid, eicosapentaenoic acid (EPA), as monotherapy has antidepressant effects. If it could be clearly established as effective such an approach would offer a valuable alternative for woman who are at risk for, or who develop, depressive disorder during pregnancy. Strongly positive placebo-controlled trials of EPA supplementation, though, co-exist with entirely negative ones. No clear reasons for these discrepancies have emerged but one possibility is that the samples studied have differed in the proportion of individuals likely to benefit from EPA supplementation. As there has been no effort to identify such individuals we propose to explore two groups of measures, both relevant to EPA's likely mechanisms of action, as potential tools for identifying individuals likely to benefit this treatment. Hypothesis: Among women who experience major depressive episodes during their first two trimesters of pregnancy, baseline measures of cytokine activity and erythrocyte PUFA concentrations will be associated, in an additive or interactive fashion, with subsequent improvement in depressive symptoms among women taking omega-3 PUFA supplementation.
The purpose of this study is to determine if omega-3 polyunsaturated fatty acids as a monotherapy have antidepressant effects during pregnancy. It will also provide pilot data pertaining to relationships between apparent response to omega-3 monotherapy and both plasma cytokine and erythrocyte essential fatty acid concentrations.
The purpose of this study is to evaluate the safety, tolerability, and efficacy of TS-121 as an adjunctive treatment for patients with major depressive disorder with an inadequate response to current antidepressant Treatment (SSRI, SNRI or bupropion).
This randomized double-blind placebo-controlled crossover study seeks to evaluate the antidepressant effect of L-leucine, an essential amino acid, in patients with Major Depressive Disorder (MDD).
Most clinical major depression responds to standard treatments (medication and psychotherapy); however, a significant subset of depressed patients (15-20%) do not respond to these treatments and are referred to as treatment-resistant major depression (TRMD). New treatments for TRMD are needed, and one promising line of research are drugs known as N-methyl-D-aspartate (NMDA) glutamate receptor antagonists. In a recent pilot study, our group demonstrated that the NMDA antagonist nitrous oxide is effective in TRMD. This application proposes to take the next important step in understanding how nitrous oxide exerts its effects in the human brain by using state-of-the-art brain neuroimaging (functional connectivity magnetic resonance imaging) in a group of non-depressed, healthy volunteers and comparing the results to a group of TRMD patients. This study involves exposing 20 non-depressed healthy participants and 20 TRMD participants to nitrous oxide and a placebo gas, to compare their brain images before and after each of the inhalation sessions. Sessions will be separated by at least one month to prevent treatment effects from carrying over into the following session. All willing and eligible subjects will undergo up to six functional connectivity MRI scans, and two inhalation sessions. Functional imaging in the brain will allow us to trace the interconnections between various parts of the brain, including those involved with emotion and depression. Other procedures will involve screening materials to ensure safety of the participants before beginning the study (i.e. no MRI scan contraindications) and that subjects meet eligibility criteria to being in the targeted age range, depression/non-depressed state, neurological disorder history, and no medication exclusions.
This pilot study aims to investigate the efficacy of fMRI-targeted repetitive transcranial magnetic stimulation (rTMS) in treatment of major depression associated with traumatic brain injury (TBI). Half of patients will receive active treatment, while the other will receive a sham treatment with the option of receiving open-label active treatment afterwards.
