Filter by:Few studies targeting obesity in serious mental illness have reported clinically significant risk reduction, and non have been replicated in community settings or demonstrated sustained outcomes after intervention withdrawal. The researchers sought to replicate positive health outcomes demonstrated in a previous randomized effectiveness study of the In SHAPE program across urban community mental health organizations serving an ethnically diverse population.
The purpose of the study is to describe the association/correlation between change in patient-reported cognitive symptoms and work productivity in gainfully employed patients receiving vortioxetine for a Major Depressive Episode (MDE).
It can be difficult to achieve remission in individuals with late-life depression (LLD) and they often require aggressive treatment. This challenge is in part due to age-related vascular changes that are common in LLD. Successful antidepressant treatment involve changes across affective, cognitive, and default mode networks. We hypothesize that in LLD, vascular disease adversely affects response to antidepressants by disrupting connectivity of these networks. The primary goal of this project is to characterize how focal vascular damage affects regional connectivity and response to antidepressants. Based on past work and pilot data, we a priori focus on the cingulum bundle and uncinate fasciculus. These key fiber bundles connect frontal, temporal, and cingulate regions involved in cognition and affective responses. Our central hypothesis is that ischemic damage to the cingulum bundle and uncinate fasciculus contributes to structural and functional connectivity deficits of those tracts. This results in a disconnection effect that alters the function of connected regions. In turn, this increases the risk of a poor response to antidepressants. Our approach is to enroll up to 130 adults over age 60 years with a diagnosis of Major Depressive Disorder. Subjects will complete clinical evaluation, cognitive testing, and MRI/functional MRI (fMRI) sessions, including an fMRI emotional oddball task that includes attentional and affective components. Participants will be stratified by cerebral lesion severity and randomized in a 2:1 ratio to a double-blinded 8-week trial of escitalopram or matching placebo. Those who do not remit will transition to an 8-week trial of open-label bupropion, an antidepressant with a different mechanism of action. This will allow us to determine if different and distinct circuit deficits affect response to antidepressants with different mechanisms of action while also accounting for the placebo response.
The purpose of this study is to test the effects of a computerized approach/avoidance training (AAT) procedure on behavioral, affective, and brain mechanisms that are important for reward sensitivity and well-being in individuals diagnosed with major depression. The training procedure is designed to modify automatic approach responses for positive social stimuli. The primary aim is to determine the effects of approach/avoidance training on the functioning of brain systems during reward processing in individuals diagnosed with major depression. A secondary aim will determine whether brain activation patterns following approach/avoidance training predict subsequent affective and behavioral responses during reward processing. An exploratory aim will test whether completing the approach/avoidance training procedure in combination with a brief computer-delivered behavioral activation program for depression will produce larger changes in depression symptoms, positive emotions, and social relationship functioning from pre- to post-intervention compared to the control training procedure.
The purpose of this study is to evaluate the feasibility of developing a microbiome probe of depression and to evaluate the microbiome change in a preliminary analysis of treatment response (n=20) vs. non response (n=20) to the antidepressant citalopram. This study is a 12 week open trial that will enroll approximately 80 participants (anticipated 40 study completers with paired biomarker data) with an episode of major depression, Bipolar I or Bipolar II and 40 age- and sex-matched healthy controls.
Lohja Depression Treatment Study is a randomized treatment trial which compares three approaches for treatment of depression:1) Interpersonal Psychotherapy (IPT), 2) Psychoeducational Group Treatment ( PeGT) and 3) Treatment as Usual (TAU). This Trial aims to test and adapt known short term treatment models for Finnish patients and circumstances.
The overall aim of this program of research is to refine and test a newly developed storytelling video intervention (sTVi) for depressed primary care patients. The purpose of the proposed project is to establish the feasibility, acceptability, and preliminary effects of the intervention for an eventual large-scale randomized clinical trial which would test the efficacy of sTVi in comparison to a control condition. To achieve the specific aims, the investigators will conduct a pilot randomized clinical trial (n = 40), with two treatment arms: antidepressant treatment as usual (aTAU) + sTVI vs aTAU + attention control videos.
The overall aim of this program of research is to develop a collaborative narrative intervention for patients with depression being treated in primary care. The purpose of the proposed project is to establish the feasibility, acceptability, and preliminary effects of our newly developed narrative intervention on depression. To achieve the specific aims, the investigators will conduct an open trial to further develop and refine the intervention (n = 10).
Task sharing mental health care through integration of mental health into primary health care (PHC) is advocated as a means of narrowing the treatment gap for mental disorders in low-income countries. In Ethiopia, it is estimated that only around 10% of people with severe mental disorders (SMDs) ever receive evidence-based treatment for their condition, largely due to scarcity of specialist mental health services. A task-sharing model of mental health care in PHC would be more affordable and accessible to the majority of persons with SMD who do not currently receive evidence-based mental health care. Furthermore, task sharing mental health care with PHC is about to be scaled up in Ethiopia in line with the National Mental Health Strategy. However, the effectiveness of the task sharing model of mental health care for people with SMD has not been evaluated systematically in a low-income country. In this study we propose to investigate non-inferiority of a task sharing model of mental health care in PHC compared to a less accessible, but more specialist, psychiatric nurse-led model of care. The specialist model of care has been demonstrated to be acceptable and associated with improved clinical outcomes for persons with SMD engaged in the service in Ethiopia thus making this an appropriate comparison model against which to evaluate non-inferiority of the task sharing model.
The purpose of this study is to learn if measures of brain chemicals from a brain scan called Magnetic Resonance Imaging and Spectroscopy (MRI/MRS) and brain activity (known as cortical excitability and inhibition) collected by Transcranial Magnetic Stimulation (TMS) are different in adolescents with depression who are in different stages of treatment. Researchers are conducting this study to learn more about how the brain works in adolescents with depression and without depression (healthy controls). This is important because it may identify a biological marker (a measure of how bad an illness is) for depression that could one day be used to identify depressed adolescents who would benefit from certain treatments (medications for example) or to monitor how well treatments are working.
