Active clinical trials for "Depressive Disorder, Major"

Antidepressants are widely used as first-line treatments for major depressive disorder (MDD). Clinical guidelines recommend 6-24 months of "maintenance" antidepressant treatment, after patients achieve symptom remission, to prevent relapse but many people stop antidepressants too soon relapse into another depressive episode. We will test non-medication treatments, negative ion therapy and light therapy, to see they can substitute for antidepressants to prevent relapse. This is a "feasibility" study to see if participants use study treatments properly, before doing a larger, definitive trial. In this 28-week study, 100 participants with recurrent MDD who are in remission with antidepressants will be treated with light therapy or negative ion therapy (with half of devices active and half inactive) while slowly discontinuing the antidepressant, and monitored for relapse.

This study is a stratified, parallel-group, single-center study utilizing multimodal imaging techniques to identify biomarkers for Major Depressive Disorder (MDD). The study goal is to identify biomarkers for MDD and treatment response that can be implemented in clinical diagnosis and care as valid and reliable measures, through monitoring neurophysiological and electrophysiological changes across the course of transcranial magnetic stimulation (TMS) treatment.

The main purpose of this study is to investigate the safety and tolerability of intermittent Theta Burst (iTBS) repetitive transcranial magnetic stimulation (rTMS), its effectiveness in alleviating depressive symptoms as well as its effects on cognition. Although iTBS rTMS is approved for use, there have been no safety and tolerability evaluations of this form of rTMS in Multiple Sclerosis (MS).

The purpose of this study is to assess the efficacy of seltorexant compared with quetiapine extended-release (XR) as adjunctive therapy to an antidepressant drug in treatment response in participants with major depressive disorder with insomnia symptoms (MDDIS) who have had an inadequate response to current antidepressant therapy with a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).

Noninvasive transcranial direct current stimulation (tDCS) is a low-intensity neuromodulation technique of minimal risk that has been used as an experimental procedure for reducing depressive symptoms and symptoms of other brain disorders. Though tDCS applied to prefrontal brain areas is shown to reduce symptoms in some people with major depressive disorder (MDD), the extent of antidepressant response often differs. Methods that map current flow directly in the brain while a person is receiving tDCS and that determine how functional neuroimaging signal changes after a series of tDCS sessions may help us understand how tDCS works, how it can be optimized, and if it can be used as an effective antidepressant. Investigators will address these questions in a two-part randomized double blind exploratory clinical trial. For this part of the study, investigators will determine relationships between target engagement and clinical outcomes (mood) and functional sub-constructs of cognitive control and emotion negativity bias, and whether imaging markers at baseline predict changes in antidepressant response. One hundred people with depression (50 in each group) will be randomized to receive either HD-tDCS or sham-tDCS for a total of 12 sessions each lasting 20 minutes occurring on consecutive weekdays. At the first and last session, subjects will receive 20-30 minutes of active or sham HD-tDCS in the MRI scanner, which will allow investigators to map tDCS currents, and track changes in regional cerebral blood flow (rCBF) pre-to- post treatment using completely non-invasive methods. At the first and last session and mid-way through the trial, participants will also complete a series of clinical ratings and neurocognitive tests.

An open-label, single-arm, clinical research study about how to make transcranial magnetic stimulation (TMS), an FDA-approved treatment, more effective for patients with late-life depression using fMRI.

The aim is to evaluate aerobic group exercise versus leisure group activities in adolescents with mild to moderate depression. Primary outcome is Children's Depression Rating Scale - Revised (CDRS-R). Secondary outcomes are Clinical Global Impressions - Severity and Improvement scales (CGI), self-reported Quick Inventory of Depression Symptomatology (QIDS- A17-SR), the self-reported Outcome Rating Scale (ORS), clinician rated Children Global Assessment Scale (C-GAS), aerobic capacity (VO2max), muscular strength, body, Body Mass Index (BMI), presence or activity of selected biological markers of neuroprotection and neuroinflammation in blood samples and a cost evaluation rated by parents with Trimbos/iMTA questionnaire for Costs associated with Psychiatric Illness - Child version (Tic-P). Further objectives are qualitative interviews to explore adolescents' experiences of the intervention as well as how their health and lifestyle are influenced and a validation of QIDS- A17-C and QIDS- A17-SR versus CDRS-R will be performed.

This study will examine the biological factors that may modulate the relationship between depression and the development of Alzheimer's disease (AD). Since the direction of causation between depression and the biological factors associated with AD is unknown, the only way to understand cause and associated risk is to treat the depressive symptoms and examine the effects on AD biomarkers. The study involves an FDA-approved treatment for major depressive disorder. It will compare the SSRI antidepressant escitalopram with placebo. The hypothesis is that a reduction in depressive symptoms will be associated with a normalization of CSF AD biomarkers as well as peripheral inflammatory markers. This research would contribute to fundamental knowledge about potentially modifiable risks of Alzheimer's disease (AD).

This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group, fixed-dose study in patients with a primary diagnosis of MDD according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) who have an inadequate response to ongoing ADT.

This is an open label prospective pilot study of two neuromodulation interventions for patients suffering from dysphoria. Dysphoria is a transdiagnostic symptom of unease or dissatisfaction experienced across a range of diagnoses, including mood disorders and pain. There is a significant gap of treatment options across conditions with dysphoria, particularly non-medicated and self-care alternatives. Many neuromodulation therapies require extensive medical resources or time to deliver. Thus, the investigators will test two non-invasive technologies administered in a manner that would reduce resources and/or time. Virtual Reality (VR) overlays the sensory system to block the external environment and provide vast range of meaningful sensory experiences. Transcranial Magnetic Stimulation (TMS) involves a magnetic pulse passing through the scalp to depolarize neurons in the outer cortex of the brain, and daily treatments over 6 weeks are currently FDA indicated for the treatment of major depressive disorder. Accelerated TMS is the delivery of treatment in a shorter period of time. The primary objective of this study to demonstrate the preliminary effectiveness, tolerability, and feasibility of these two interventions: Guided Meditation VR for Wellness and Accelerated Transcranial Magnetic Stimulation.
