Filter by:The purpose of this study is to determine if LY03005 is effective and safe in improve MADRS score, as compared to placebo (no medicine) in participants with Major Depressive Disorder (MDD)
The study is looking at assessing monoamine oxidase B (MAO-B) occupancy in depressed patients before and after medication treatment using positron emission tomography (PET) scan.
To test our hypotheses, we will enroll healthy adults having no history of mood disorders and adults with major depressive disorder (MDD) having a broad range of depressive symptom severity. After screening, subjects will meet with the research coordinator or an investigator for a discussion, with opportunity for questions, before applicable consent forms are obtained. Daily stress processes will be assessed using an ecological momentary assessment approach for 8 consecutive days. On the last day of the daily stress assessment, we will directly measure muscle sympathetic nerve activity, blood pressure, and heart rate during acute laboratory-based cognitive, emotional, and physiological interventions to induce a stress response. A venous blood sample will be taken for measurements of metabolic and renal health and systemic inflammation. Aim 1: To examine the effect of daily psychosocial stressor exposure on acute sympathetic stress reactivity in MDD. Two stressor exposure indicators will be calculated: stressor frequency (i.e., percentage of interview days during which at least one stressor occurred) and total stress (i.e., total number of stressors reported across all interview days) and will be related to the magnitude of responsiveness to the acute stress interventions. We hypothesize that the slope of this relation will be steeper in adults with MDD compared to healthy non-depressed adults. Aim 2: To determine the relation between negative affective reactivity to daily psychosocial stressor exposure and acute sympathetic stress reactivity in MDD. Negative affective reactivity will be calculated as the change in affect on days when stressors occurred compared to one's typical affect on non-stressor days and will be related to the magnitude of responsiveness to the acute stress interventions. We hypothesize that the slope of this relation will be steeper in adults with MDD compared to healthy non-depressed adults.
This is a randomized, double-blind, placebo-controlled clinical trial to assess the efficacy and safety of PRAX-114 in participants with moderate to severe major depressive disorder (MDD). Participants will be randomized to receive 28 days of either 40 mg PRAX-114 or placebo in a 1:1 ratio.
The clinical trial will investigate the effect of brexpiprazole on the concept of life engagement in participants with Major Depressive Disorder (MDD) with a current depressive episode.
Comparison of efficacy treatment (respond, remission) between the optimized treatment group (dose adjustment or early change other drug based on the change of total score HAM-D 17) and the routine treatment group (start with the lowest effective dose and adjust dose slowly) for depressed patients in Viet Nam
Patients who suffer from MDD recieved ketamnie (2014-15) in open study will be addressed and there depression mood will be evaluated using the rating scale that were used in the original research. In addition time of relapse and questions about their medications and drug use will be performed.
The investigators propose a study of telehealth supervised, caregiver-delivered, home-based transcranial direct current stimulation (tDCS) for antidepressant treatment of patients with an acute depressive episode.
This trial is a randomized, double blind, controlled pilot study that will compare bilateral theta burst stimulation (TBS) and sham treatment for patients with opioid use disorder (OUD) and Major Depressive Disorder (MDD) experiencing suicidality.
The purpose of this study is to investigate the effects of a multispecies probiotic on the function of the vagal nerve in patients with major depression and healthy participants in a single-center, randomized, placebo-controlled trial.
