Active clinical trials for "Depressive Disorder"

This is a preliminary, open-label, clinical trial designed to assess the efficacy, safety, and tolerability of vortioxetine for the treatment of major depressive disorder in patients with coronary artery disease. In addition, the study will assess the effects of vortioxetine on heart rate variability in these patients.

This study evaluates the use of brain activity monitoring for early identification of pharmaceutical treatment efficacy and development of depression deterioration events.

Depression is the leading cause of disability worldwide and a risk factor for other diseases. While women are at elevated risk for depression in general, the menopause transition is a particularly vulnerable time for many women, with the risk for depression increasing 2-4 fold. The objective of this research study is to determine whether mindfulness-based stress reduction (MBSR), an 8-week structured intervention involving meditation and yoga, has any beneficial mood effects for women undergoing this vulnerable time.

During this project the investigators will develop and pilot test a companion intervention for fathers (Fathers and Babies-FAB), to supplement the Mothers and Babies Course (MB) that provides stress and mood management tools for home visiting clients. Focus groups with prior study participants, their male partners, and home visiting staff will be used to develop the FAB curriculum and protocol. FAB text messages aim to improve the mental health of the male partner and help him support his partner's mental health. Feasibility, acceptability, and outcome measures will be supplemented with assessments of fathers' mental health and partners' relationships. Participant assessments will be conducted at baseline, 3 and 6 months in this uncontrolled pilot study. The public health significance and innovation of this project is substantial. If the investigators are able to integrate MB-TXT and MB-DAD into home visiting programs and generate improved mental health outcomes for home visiting clients and their partners, the investigators will be prepared to replicate this intervention across home visiting programs nationally at a time when home visitation as a service delivery model for families with infants and young children is rapidly proliferating through federal funding.

The purpose of this study is to assess the feasibility and acceptability of a family-based preventive intervention designed to reduce sexual risk behaviors and depressive symptoms among South African adolescents and their parents/guardians/caregivers.

Depression affects up to 20% of people in their lifetime and can be a severe debilitating illness. Indeed, the World Health Organisation has estimated that depression will soon be the second leading contributor to the burden of disease worldwide. One of the big problems for patients and doctors is that currently available antidepressant drugs and psychotherapies do not work for 30% of people. However, about 60% of such treatment-resistant patients will recover fully with electroconvulsive therapy (ECT). Even though it was developed over 75 years ago, ECT continues to be the most powerful treatment for severe, often life-threatening, depression. Despite that, we have recently reported that severe depression symptoms return (called a "relapse") in nearly 40% of such responders within six months of completing a course of ECT. Actually, such high relapse rates are seen for all patients with treatment-resistant depression, irrespective of what treatment they have received. There is thus an urgent need for better treatments to prevent relapse and one such possibility is an old drug called ketamine. Ketamine blocks the activity of glutamate, one of the major chemical messenger systems in the brain. Because of this effect it is sometimes used as an anaesthetic but it can also make you feel a bit "high" and so is sometimes abused as a recreational drug. Fortunately, in small doses it is quite safe. Recently, it has been found that ketamine has a remarkably rapid, but brief, antidepressant effect, including reducing suicidal thoughts. We wish to evaluate ketamine as a way to reduce relapse rates in people who have just been treated successfully with ECT for severe depression. Developing such a new treatment, and understanding how it works, would be of tremendous benefit to persons with severe depression, their families, and the wider society.

rTMS is a promising, though largely untested, option for treating adolescent and young adult depression. This study hypothesizes that rTMS will safely and significantly alleviate depression and decrease suicidal ideation in adolescents and young adults based on previous studies.

This study will determine the effectiveness of antidepressant medication in preventing depression and improving recovery in people who have been supported by mechanical ventilators in an intensive care unit (ICU).

This study will be conducted in healthy volunteers to investigate the effect on intraocular pressure of 2 weeks of treatment with 300mg WELLBUTRIN XL/day.

Recent studies show that 25 - 30% of depressed patients never fully recover, resulting in a treatment-resistant condition. Thus, depression is a major cause of human suffering. We are interested in finding new ways of identifying and alleviating treatment-resistant depression, and we believe that recent advances in brain imaging can contribute to achieving that goal. In this project, we will use a novel compound ([N-methyl-11C]mirtazapine) that we invented for examining the neurochemistry of brain receptors involved in antidepressant actions. Our compound, [N-methyl-11C]mirtazapine, is closely related to the clinically effective antidepressant drug mirtazapine (Remeron®). It labels several types of noradrenergic receptors that have often been implicated in "stress reactions" as well as depressive disorders. We believe that our compound can identify specific molecular brain dysfunctions that are causally related to treatment-resistant depression. The purpose of this study is to determine whether there is a reliable relationship between the level of mirtazapine in the bloodstream and the occupancy of neuroreceptors by mirtazapine in the brain. We will apply our standard procedures of PET brain scanning and region-of-interest data analysis, using healthy volunteers who will receive a daily dose of mirtazapine (double-blind design with placebo, 7.5 mg or 15 mg daily for 5 days). We believe that this project could provide a procedure for assessing brain function in treatment-resistant depression, with the aim of improving the guidelines for successful, evidence-based treatment of depression.
