Filter by:The purpose of this study is to investigate the structural, functional and chemical brain abnormalities in patients with first episode psychosis and assess the evolution of these abnormalities during the course of the disease.
The purpose of this study is to evaluate the efficacy, safety, and tolerability of two doses (50 and 100 mg) of NBI-98854 administered once daily for the treatment of Tardive Dyskinesia (TD) symptoms.
This study is aimed at evaluating whether the computer-based cognitive exercises in the Thinking Skills for Work (TSW) program are critical to improving work and cognitive outcomes in consumers with serious mental illness and cognitive impairment enrolled in supported employment (SE), or whether a streamlined version of TSW without this component (the Cognitive Skills for Work (CSW) program) is equally effective for some or all consumers. An RCT will be conducted at two sites (Mental Health Center of Greater Manchester in New Hampshire and Thresholds Inc. in Illinois) with 244 consumers randomly assigned to one of two groups (122 each, with approximately 122 participants having schizophrenia or schizoaffective disorder and 122 of the participants having other diagnoses): 1) TSW, or 2) CSW. The TSW and CSW programs will be delivered by the same Cognitive Specialists, who will work as members of the SE team to integrate cognitive and vocational services. All participants will continue to receive SE services. Participants will be assessed at baseline, post-treatment at 8 months (after completion of the active teaching components of TSW or CSW), and at 16 and 24 months post-baseline to evaluate cognitive functioning, symptoms, and quality of life. All work outcomes will be tracked weekly. In addition, a supplementary study, commencing in September 2015, will assess a promising biomarker for understanding the mechanisms underlying the effects of cognitive remediation, brain-derived neurotrophic factor (BDNF), in new enrollees in the parent R01 study. This supplement will complement the aims of the parent R01 by shedding light on possible mechanisms related to how TSW works and for whom, thereby informing efforts to refine and improve the program, as well as targeting individuals who fail to benefit. The supplement will take place at the same sites as the parent R01.
People with serious mental illness have difficulty making good use of primary care, and die, on average, years earlier than others in the population. The greatest contributors to this premature mortality are medical illnesses, especially cardiovascular disease and cancer. The Patient Centered Medical Home is a model for reorganizing primary care practice so that healthcare is more effective, efficient, and user-friendly. It has been implemented across VA as the, "Patient Aligned Care Team" (PACT). It is unclear, however, how this PACT model applies to people whose predominant illness is treated by specialists. This is the case for people with serious mental illness (SMI), many of whom receive ongoing treatment at mental health clinics. To achieve optimal health outcomes in the population with SMI, it may be necessary to adapt the PACT model so that it includes approaches that have proven to improve healthcare in this population. This project implements an adapted "SMI-PACT" model, and evaluates its effect on Veterans with SMI.
The purpose of this study is to evaluate the use of the drug isradipine for cognitive enhancement in patients diagnosed with schizophrenia and schizoaffective disorder.
The purpose of this study is to examine an Adaptive Treatment approach in order to improve outcomes of youth with Cannabis Use Disorders who are poor responders to treatment.
In the current study, the investigators propose to measure the five domains of social cognition identified by the National Institute of Mental Health (NIMH) as relevant to individuals with psychosis (i.e., theory of mind, attribution style, emotion recognition, social perception, and social knowledge). The investigators will also explore the association between different domains of social cognition and outcomes relevant to psychotic disorder (e.g., symptomatology, social functioning, and vocational functioning).
The purpose of this study is to use proton magnetic resonance spectroscopy (MRS) at 4 Tesla to measure brain glycine levels noninvasively at baseline and for 2 hours after a single oral dose of a concentrated glycine-containing beverage, and to compare MRS glycine measurements to glycine blood levels in samples obtained after each MRS spectrum. The investigators hypothesize that they will observe a high correlation between the magnitude increases in brain and plasma glycine levels over this time frame. The investigators also hypothesize that we will observe large intersubject variability in glycine uptake rates into brain and blood. The investigators also hypothesize that subjects with a glycine decarboxylase (GLDC) mutation (triplication) will have lower baseline plasma and brain glycine levels and will experience smaller brain and plasma glycine increases after glycine consumption than controls or family members without the GLDC mutation.
A study to examine whether an antipsychotic combination treatment of olanzapine and amisulpride is more effective than olanzapine and amisulpride alone.
The objective of this sensory analysis study is to determine whether volunteers observe a significant difference in organoleptic properties between lamotrigine (430C78) cherry flavoured orally disintegrating tablets (ODT) and a placebo cherry flavoured orally disintegrating tablet. The aim is to assess the value of the placebo as a marketing aid, whereby physicians and patients may assess the personal acceptability of the organoleptic properties and potential convenience prior to prescription of the ODT formulation.
