Filter by:The purpose of this study is to (a) measure how brain structure, metabolism (how the brain uses energy), and function predict response to electroconvulsive therapy (ECT) for treatment of depression; and (b) measure how ECT changes brain metabolism and function. We will ask you to undergo magnetic resonance imaging (MRI) at three sessions: (1) prior to your first ECT therapy session, (2) after having 4-6 ECT therapy sessions, and (3) approximately two months following your first ECT therapy sessions.
Depression is highly prevalent among patients with heart failure (HF) and associated with lower levels of health-related quality of life and physical functioning, and higher risk of rehospitalization and mortality, and higher health costs. This Project will compare the effectiveness of a "blended" telephone-delivered collaborative care intervention for treating both HF and depression to: (1) collaborative care for HF-alone ("enhanced usual care"; eUC); and (2) doctors' "usual care" for depression (UC). If proven effective and cost-effective, the potentially more powerful, scalable, efficient "blended" care approach for treating HF and co-morbid depression could have profound implications for improving chronic illness care and stimulate development of "blended" interventions for treating other clusters of related medical conditions.
Prospective, multicenter, non-comparative, observational program to describe prevalence of depressive symptoms in a variety of neurological disorders and effects of Fevarin® on the severity of anxiety and depression, sleep state, and cognitive function.
Bupropion hydrochloride was first approved on 30 December 1985 in United States for depression and is currently approved in 80 countries. Bupropion has also subsequently been approved for smoking cessation and for seasonal affective disorder. Cumulative exposure to bupropion is estimated at approximately 97.3 million patient exposures up to 31 December 2012. Bupropion hydrochloride is a weak catecholamine reuptake inhibitor predominantly affecting serotonin, norepinephrine and dopamine. Its mechanism of action and its structural similarities to diethylpropion, amphetamines, and cocaine, bupropion resembles stimulants in many respects, leading to concerns about potential abuse of the product. Abuse potential had been part of the Benefit Risk Management Plan for bupropion up until 2003 and at that point, had no longer been regarded as a potential risk that required additional/further evaluation outside standard pharmacovigilance monitoring. The current European Risk Management Plan also states that standard pharmacovigilance monitoring applies to abuse potential. Monitoring has shown a recent increase in the number of spontaneous reports from the Adverse Event reporting System (AERS) of drug abuse. The bupropion team agreed that although the numbers of abuse reports was small relative to the total number of reports for bupropion in OCEANS, there was sufficient information in AERS to warrant investigation of the potential effect on public health. To investigate the degree of misuse and abuse of bupropion (including non-oral routes of administration) in the United States, the Drug Abuse Warning Network will be used to examine the study period 2004-2011.
This study aims to determine whether ventral striatal dopamine release is a mechanism of reward motivation in major depression, whether dopamine release is low in depression, and whether DA release and reward motivation predict response to dopamine-targeted treatment with pramipexole.
This randomized effectiveness trial evaluates a quality improvement intervention aimed at providing access to evidence-based depression treatments (particularly cognitive-behavior therapy for depression and or pharmacotherapy) through primary care for youth ages 13-21, as compared to enhanced usual care. The major hypothesis is that the quality improvement intervention will be associated with improved outcomes, relative to enhanced usual care.
The purpose of this study is to determine whether group visits with added behavioral activation (BA) for depression will have a greater clinical impact than our standard group visits without BA for depression in reducing the risk of future coronary events as measured by the United Kingdom Prospective Diabetes Study (UKPDS) risk engine and depression symptoms as measured by Patient Health Questionnaire-9 (PHQ-9) after 6 months.
The main objective is to compare the physiological reactivity (heart and respiratory rates, galvanic skin response, cerebral perfusion, and startle) in the three phases of emotion between depressive subjects, subjects remitted from depression and control subjects.
The purpose of this study is to examine the effects of exercise on the symptoms of depression using serum levels of serotonin, catecholamine's, Alpha EEG asymmetry, and self-report of symptoms as markers. In an attempt to further understand the mechanisms of improved mood through exercise; this study will examine the known factors that contribute to depressed mood in a single study using serotonin and catecholamine levels via blood serum and EEG slow wave asymmetry. Such information can be useful in understanding the overall neurological components of depression and the effects of exercise on the brain in depressed individuals that would make the prescription of exercise a viable treatment option.
To provide better care and preventive services for people with both depression and diabetes, the investigators propose to develop and test whether interventions to reduce depressive symptoms can be integrated into routine diabetes clinics in India. The investigators will gather feedback from patients in India through focus group discussions and individual interviews so they can culturally-adapt a model of combined depression and diabetes care. The investigators will then evaluate the effectiveness and costs of this care model in a trial at four diabetes clinics in India. It is expected that results from this study can guide how to incorporate mental health care into routine diabetes clinics in low-resource settings.
