Active clinical trials for "Depressive Disorder, Major"

The purpose of this study is to evaluate a computer-guided, telephone-based therapy for adolescent depression, delivered in a pediatric primary setting in the community.

Ketamine infusion has been shown to have rapid antidepressant properties, however the possible use of ketamine in treatment-resistant depression as augmentation has not been investigated. The overall aim of this study is to assess the feasibility, safety and tolerability, efficacy and duration of the effect of intravenous N-methyl-D-aspartate antagonist ketamine as augmentation of antidepressants for chronic suicidal ideation in subjects with severe treatment-resistant depression (TRD). This is an open-label study (pilot).

Safety and Efficacy of Vilazodone in Major Depressive Disorder

Primarily, this study seeks to evaluate whether citalopram treatment is associated with an increase in the Glutamine (Gln)/Glutamate (Glu) ratio in the anterior cingulate cortex (ACC) from baseline to day 3 of treatment. Additionally, this study would like to examine whether citalopram treatment is associated with an increase in the Gln/Glu ratio in the ACC from baseline to day 7 of treatment. In order to more fully examine baseline neurochemical and functional abnormalities in participants with MDD, we also seek to scan a group of age- and sex-matched non-depressed comparison individuals in order to perform between-group analyses of baseline neuroimaging measures.

Depressed patients will be offered experimental treatment with a new, potentially fast-acting antidepressant called ketamine while being scanned by magnetic resonance imaging (MRI) to measure the chemical effect of the drug. Ketamine will be given in a dose of 0.0 (placebo), 0.1, 0.2, 0.3, 0.4, or 0.5 mg/kg. If a patient does not respond to ketamine after the first infusion, it may be because s/he received ketamine placebo or the dose of ketamine was too low. In that case, an optional second scan and infusion of active ketamine (0.5 mg/kg) will be offered. This second scan will occur no later than weeks after the first scan/infusion (as scheduling permits). There is no guarantee that the patient will respond to the second ketamine infusion. Patients enrolled in the study are eligible for up to 6 months treatment with their study psychiatrist after the ketamine infusion(s). Healthy Volunteers: Healthy controls will receive an infusion of ketamine at a single dose (0.5 mg/kg). Volunteers will only receive one MRI scan and infusion.

The purpose of this study is to understand the effectiveness of a ten-week internet-based cognitive behavioral therapy (iCBT) treatment on improving depressive symptoms, coping and resilience skills, and cognitive processing.

The main aim of this study is to (1) evaluate the effectiveness of metacognitive therapy for major depressive disorder. Additional aims are to (2) investigate patterns of change and the mechanisms of action involved during treatment, and to (3) examine the impact of meta-cognitions in the treatment and relapse prevention of depression.

The Institute of Medicine identifies Prolonged Grief (PG) as a critical under-addressed public health problem for which are no empirically supported treatments. The purpose of this application is to pilot-test Behavioral Activation (BA) therapy for PG. BA is a well supported, stand alone intervention for depression and recently applied to posttraumatic stress disorder, which reduces rumination and avoidance behaviors that otherwise thwart access to natural rewarding contingencies and resources. The treatment focuses on promoting stable, active routines, self-care behaviors, enhanced self-efficacy, and reengagement with pleasurable activities and significant social resources. Rumination, disengagement, and low self-efficacy are defining features of PG. Further, in response to loss of intimates, the key factors that differentiate resilient people from those that have difficulties adapting is the maintenance or fast resumption of social and occupational functioning. Thus, the main hypothesis of this study is that BA for PG will result in clinically significant reductions in rumination and functional disengagement. This is a preliminary small-scale pilot assessment of potential efficacy and feasibility of completing a large scale study of BA for PG.

The current study is being conducted in patients with major depression. The study aims to 1) investigate the combined effects of selective serotonin reuptake inhibitor (SSRI) and bupropion compared to SSRI alone on the improvements of depressive symptoms, fatigue, hypersomnia, and neurocognitive functions, 2) observe structural/functional/chemical changes using magnetic resonance imaging (MRI), 3) and examine a relationship between the improvements of depressive symptoms, fatigue, and hypersomnia and the neural changes.

The objective of this study is to evaluate the feasibility of adding a navigational system to traditional repetitive Transcranial Magnetic Stimulation (rTMS, referred to in this application as nTMS) as a way to establish and maintain precise coil positioning (contact, rotation, and tilt) and consistent brain region targeting throughout a nTMS treatment session and in subsequent nTMS sessions.
