Active clinical trials for "Depressive Disorder"

This will be an open label, non-randomised [11C]PHNO PET study using healthy male volunteers. Each volunteer will undergo 4 [11C]PHNO PET scans to allow for further characterisation of this radioligand and examine the effects of [11C]PHNO mass carry-over and displaceable binding in the brain. This study aims to obtain data from 6 evaluable subjects.

Sleep deprivation can acutely reverse depressive symptoms in patients with major depression. Although underlying mechanisms of the antidepressant action in sleep deprivation are unclear, many of these observations can be explained by abnormal slow wave homeostasis. This study will test the prediction that selectively reducing slow waves during sleep (slow wave deprivation; SWD), without disrupting total sleep time, will yield an antidepressant effect.

Persons with serious mental illness (SMI) are at increased risk of cardiovascular disease (CVD). The goals of this study are to test a treatment, Life Goals Collaborative Care to help promote health behavior change and improve mental health and physical health-related quality of life, as well as to get feedback from patients and providers on what is needed to help better coordinate the physical and mental health care of these patients.

This is a two part study. The objective of Part 1 is to evaluate the safety, tolerability, and pharmacokinetics of HT-2157 in healthy normal volunteers Part 2 is a randomized, double-blind, placebo-controlled, multiple (21-day) ascending-dose evaluation of the safety, tolerability, pharmacokinetics, and pharmacodynamics of HT-2157 in patients with major depressive disorder

The investigators propose to study and compare measures of brain energy metabolism in geriatric bipolar individuals and healthy older adults. The investigators would also like to investigate changes in brain energy metabolites associated with CoQ10 administration in older bipolar individuals. Finally, resting state functional Magnetic Resonance Imaging (fMRI) will be conducted in order to explore frontal and limbic circuitry in geriatric bipolar disorder. Primary Hypothesis: Baseline beta NTP and NAA will be lower, and PCr and lactate higher in Geri BPD compared with older healthy controls Secondary Hypothesis: Changes in PCr and beta NTP will be demonstrated in Geri BD group challenged with CoQ 10.

This is a multicenter, randomized, double-blind, placebo-controlled, parallel, multiple dose study designed to evaluate the safety and tolerability of the co-formulation of ALKS 33 with buprenorphine (ALKS 5461) in subjects with Major Depressive Disorder (MDD) who are inadequately/partially responding to current treatment with a stable dose of a serotonin-selective reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).

The purpose of the study is to determine whether motivational interviewing with guideline-based medical management for depression will significantly improve time to depression recovery and increase the proportion of subjects in recovery compared to guideline-based medical management alone over 9 months.

This study will examine changes in brain dopamine transporter activity before and after antidepressant therapy.

Depression in cardiac patients is common, persistent, and deadly. However, the vast majority of cardiac patients with depression go unrecognized and untreated, despite the existence of treatments that clearly improve depressive symptoms and may favorably impact survival. Our research group and others have found that depression recognition and treatment appears particularly limited among patients with acute cardiac illness, though this population may be the most vulnerable to the deleterious effects of depression. We propose a project, building on successful collaborative care depression management programs in outpatient settings, to address this important issue. The specific hypotheses behind the proposed research are that a collaborative care depression management program can be successfully adapted to inpatient cardiac units, and that such a program will lead to greater rates of adequate depression treatment and improvements in secondary outcomes. The following specific aims capture the stepwise goals of this program: To determine whether a collaborative care depression management program ('Enhanced Care') leads to significantly increased rates of adequate depression treatment compared to usual care (screening and feedback) (Primary Aim). To assess whether this Enhanced Care program has a lasting impact on adequate depression treatment, depressive symptoms, health-related quality of life, and adherence to medical recommendations at 6 weeks, 12 weeks, and 6 months, compared to usual care.

This study evaluates the efficacy of acupuncture and massage for the treatment of depression during pregnancy. The study also examines differential effects of study treatments on delivery outcome and post partum depression.
