Filter by:The MoodNetwork, a patient-powered research network (PPRN), is one of 18 PPRNs participating in Patient-Centered Outcomes Research Institute's (PCORI) PCORnet network. Its objective is to improve the nation's capacity to conduct comparative effectiveness research that reflects questions of greatest importance to patients and other stakeholders. A robust data infrastructure will be built that, in phase one, allows participants to contribute data, including those from participant questionnaires, visualize their own health information in intuitive and helpful ways, and share their aggregated de-identified health information within and outside of the Network.
This is a randomized, control group design of pharmacogenetic implementation in a mental health population of subjects taking anti-depressants and/or anti-psychotics with a new or current primary or secondary diagnosis of Major Depressive Disorder (MDD) or Depressive Disorder Not Otherwise Specified (DDNOS).
The specific focus of this study is to gather data regarding the effects of a psychological therapy known as Problem Solving Therapy (PST) on cerebral blood flow (CBF), cortical gray matter (GM) atrophy, subcortical white matter (WM) lesion burden, and measures of cognitive function in subjects with Late Life Major Depressive Disorder (LLD). This research goal will be achieved by recruiting 110 individuals over the age of 65 with LLD. The primary outcomes will be change in CBF, change in GM atrophy, change in WM lesion, change in cognitive function, and change in depression severity from baseline to the end of 12 weeks of PST.
The purpose of this study is to evaluate the long-term safety and tolerability of vilazodone for the treatment of MDD in pediatric outpatients (7-17 years).
The purpose of this study is to evaluate the efficacy, safety, and tolerability of levomilnacipran ER relative to placebo in adolescent outpatients (12-17 years) with Major Depressive Disorder (MDD). In addition, the study is designed to obtain pharmacokinetics (PK) data to guide dose selection for future pediatric studies of levomilnacipran.
The purpose of this study is to research the effects of ketamine on brain function in patients with Major Depressive Disorder (MDD). This study is an ancillary MRI neuroimaging study being conducted in patients with MDD who are enrolled in a separate clinical trial. Healthy control volunteers are also enrolled. No drug or other intervention is given as part of this protocol per se. To study brain activity related to emotion, the study team will use a technology called functional MRI (fMRI), which is a method for evaluating the flow of blood in the brain using a powerful magnet. fMRI does not involve exposure to radiation. Patients will be shown a sample of images on a computer screen designed to bring about an emotional reaction. The MRI machine will then take a number of pictures of your head. By computer analysis, this machine is able to create a picture of your brain's activity. There are several tasks during scanning that involve looking at various images that represent different emotions, and the study team will be monitoring brain activity during these tasks. Patients will be scanned before and 24 hours after receiving ketamine (as part of a separate study) to analyze treatments effects. These scans are compared to depressed patients who did not receive ketamine, as well as to healthy controls.
Depression is a disorder that causes major harm to physical health and social life. It induces isolation, reduced physical and work capacity and increasing the risk of death. In contrast, exercise helps to maintain quality of life, also inducing improvement of cognitive functions, stimulation of brain plasticity and resilience, in addition to promoting self-esteem and social interaction. The precise mechanisms by which exercise improves symptoms of depression are not fully clear, but it is probably multifactorial. In this project, the investigators aim to investigate variables that provide additional information about biomarkers involved in the pathophysiology of depression and therapeutic response to exercise. The investigators expect to find changes in biomarkers associated with potential mechanisms of neuroprotection (cytokines, markers of oxidative stress, Brain-derived neurotrophic factor (BDNF), cortisol) after exercise program and the role in the therapeutics of depression. To evaluate functional assessment indices will be used ergospirometry, a test that determines the respiratory, cardiovascular and metabolic activity. Overall, this project will help to investigate alternative adjunctive treatments for depression and their associated biomarkers with response.
Cognitive deficits are a core feature across disparate brain disorders, being highly prevalent and pervasive. Impairments in executive function are one of the most consistent findings in clinical and meta-analytical studies and were reported to be a principal mediator of psychosocial impairment and disability. Cognitive dysfunction is thought to be underlied by abnormalities in distributed brain circuits, at the cellular and molecular levels. Nonetheless, the neural mechanisms underlying the dysregulation in these circuits are poorly understood. Emerging evidence indicates that metabolic abnormalities are highly relevant for the domain of cognitive function and indicate that alterations in metabolic pathways may be relevant to neurocognitive decline across different populations. The incretin glucagon-like peptide-1 (GLP-1) is a hormone secreted by intestinal epithelial cells. GLP-1 receptors are widely expressed in the central nervous systems. Pre-clinical trials have demonstrated significant neuroprotective effects of GLP-1. Ongoing clinical trials measuring cognition and mood in populations with various psychiatric disorders lend further impetus to explore the effects of GLP-1R agonists on brain structure and cognitive function. We hypothesize that GLP-1 and the GLP-1R are relevant for molecular and cellular processes that are thought to underlie the formation and maintenance of brain circuits. A derivative of this hypothesis is that the administration of GLP-1 agonists may result in enhanced neuronal survival and consequential increase in gray matter volume. We therefore propose to explore the cellular and molecular abnormalities within and between neural circuits subserving cognition using the GLP-1R agonist liraglutide. The overall goal of this study is to explore the relationship between a metabolic molecular target (i.e. the GLP1 system), the neural circuits of interest and the behavioral phenotype cognitive function.
Ketamine has been shown to have an antidepressant effect when given intravenously in doses of 2mg/kg. Ketamine is used as a standard induction drug during general anesthesia. It is known in this instance to decrease postoperative pain. No one has studied whether or not ketamine when given in doses used during general anesthesia (0.5mg/kg intravenous) has an antidepressant effect on surgical patients who suffer from depression. The study is designed to determine whether or not a small dose of ketamine when given at the induction of anesthesia could have an antidepressant effect on surgical patients with depression.
The study is a three year research project whose aims are to evaluate the willingness of individuals with serious mental illness to initiate the two illness self-management interventions- WRAP or FOCUS, to examine and compare participant engagement, satisfaction, and outcomes (symptoms, recovery, quality of life) in the two interventions.
