Active clinical trials for "Depressive Disorder, Major"

This study aims to identify a novel enhancement strategy for residual symptoms of major depressive disorder (MDD) Dopamine (DA) has been viewed as a "pleasure neurotransmitter" for over 30 years. Yet recent data from animal and human studies suggest that dopamine has greater effects on "wanting" than on "liking." Therefore, the investigators of this study have hypothesized that amphetamine/d-amphetamine (AMPH), a medication which increases dopamine transmission in the reward centers of the brain, may have a more powerful antidepressant effect in combination with well-being therapy (WBT), a specific type of cognitive-behavioral therapy, which helps individuals with depression to increase their contact with natural rewards and decrease reward-interfering thoughts. The investigators will test their hypothesis by randomizing 40 individuals with residual symptoms of depression, already taking an antidepressant that affects serotonin (e.g. Prozac, Paxil), to 8 weeks of treatment with either WBT in combination with AMPH, or WBT with pill placebo. The effectiveness of each treatment will be measured using a reliable scale, called the Hamilton Depression Rating Scale. The investigators have also hypothesized that people assigned to the stimulant/WBT group will have greater improvements in functioning, well-being, and positive affectivity than those the people assigned to the WBT/placebo group.

The purpose of this study is to assess the safety and effect of TC-5214 as a single therapy in patients with major depressive disorder who exhibit inadequate response to antidepressants.

The purpose of this study is to test the clinical efficacy of two psychotherapies for early onset chronic major depression, including Behavioral Activation (Jacobson et al., 2001), and an integrated version of Behavioral Activation and Stress Innoculation Coping (BASIC) for short-term (16 weeks) of individual psychotherapy for adults with chronic major depression. The control condition is an individual workbook condition of Behavioral Activation. These psychotherapies focus on behavior activation, stress reduction and coping strategies to counter depressive symptoms.

The investigators are doing a research study to find out if riluzole, when taken along with a standard antidepressant (sertraline) can help people with major depression. This research study will compare riluzole + sertraline to placebo + sertraline. The investigators hypothesize that adding riluzole will lead to a better antidepressant response, in less time, then sertraline alone.

Patients with major depression who are on a waiting list for psychotherapy usually suffer from considerable symptoms. Online self-help is one potential way to alleviate this suffering. The investigators want to study if patients awaiting psychotherapy benefit from online-self help. The investigators therefore randomly assign patients to either online self-help or no intervention and assess their depressive symptoms on a regular basis. The investigators hypothesize that online self-help will be superior to no intervention in alleviating depressive symptoms in depressed patients awaiting psychotherapy.

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.

The Canadian Rapid Treatment Center of Excellence (CRTCE) is a healthcare facility principally focused on providing best practices of intravenous ketamine treatment to adult patients suffering from mental health conditions. The center focuses specifically on treating individuals suffering from major depression disorder, bipolar disorder, post-traumatic stress disorder and obsessive compulsive disorder as their primary diagnosis. Herein, this retrospective analysis aims to look at past data in order to further develop our understanding of ketamine in the use of psychiatry.

The purpose of the current study is to perform a unified, homogeneous data collection protocol that includes a large cohort of patients undergoing different treatment options for Major Depressive Disorder (MDD) as an avenue for investigating optimal biomarkers for depression treatments on an individual patient level.

The purpose of this research is to see if information from blood and data from smartwatches can be combined to help diagnose depression and determine if transitions between active depression and treated depression can be predicted.

Hypothesis I: Patients in the SSRI + ramelteon treatment group will achieve remission (defined as an IDS-C30 score of 11 or less) more quickly than those in the SSRI + placebo group.
