Filter by:Improvement of clinical long-term outcome through the implementation of early detection and intervention within a specialized network of integrated care (ACT and hometreatment) for adolescents and young adults with a first episode of psychosis between 12 and 29 years.
This is a randomized, double-blind, placebo-controlled, sequential cohort, ascending oral dose study of the safety, tolerability, pharmacokinetics, and pharmacodynamics of EVP-6308 administered for 14 days in subjects with schizophrenia who are on a stable anti-psychotic regimen.
The purpose of this study is to evaluate the effectiveness of a mobile real-time cognitive behavioral intervention for serious mental illness (SMI) and to identify the facilitators, barriers, and costs of implementation. We would like to determine whether the addition of a mobile phone monitoring software program to a brief behavioral intervention for bipolar disorder or schizophrenia improves symptoms arising from the disorders. In this study we will be assessing the feasibility, acceptability and short term effect of the mobile phone enhanced intervention for bipolar disorder and schizophrenia.
Randomized, double-blind clinical trial of tocilizumab vs. placebo as add-on treatment for residual positive, negative, and cognitive symptoms in schizophrenia. The primary study hypothesis is that individuals receiving tocilizumab will show greater improvements in their PANSS total scores than those taking placebo.
The early stages of schizophrenia are associated with significant decreases in social and intellectual abilities, with more declines in chronic disease. Studies have identified relationships between duration of untreated psychosis (the duration between the onset of positive symptoms and treatment) and worse long term outcomes. However, the neurobiology of this phenomenon and its implications for response to antipsychotic medications remain poorly understood. Glutamatergic excess altering brain connectivity might provide an explanation for why those with longer duration of untreated psychosis have worse clinical outcomes. The investigators propose to use neuroimaging to study 67 first episode psychosis subjects before and after sixteen weeks of treatment with risperidone, a common antipsychotic. We will measure (1) glutamate and (2) structural and functional brain connectivity and test the hypotheses that glutamatergic abnormalities are present in first episode patients and that longer duration of untreated psychosis is associated with greater connectivity abnormalities that set the stage for poor response to treatment. 67 demographic-matched controls will also be recruited as a comparison group - healthy controls will not receive antipsychotic medication. The investigator's previous studies have made progress in the understanding of abnormalities in the glutamate system and brain connectivity in unmedicated patients with schizophrenia and modulation of these by antipsychotic medication. Two indices of glutamatergic dysfunction have been identified. While antipsychotic medications appear to modulate glutamate, the disturbance in the relationship between metabolites is not restored with treatment. In addition, the investigators found that both structural and functional connectivity abnormalities in unmedicated patients with schizophrenia predict patients' response to treatment. To the investigator's knowledge, no other group has performed a study that uses a combination of complementary neuroimaging techniques that will allow generating a broad characterization of glutamatergic function and brain connectivity in first episode psychosis and change with treatment. The results of the proposed studies could suggest a mechanism by which the duration of untreated psychosis is associated with poor treatment response which might lead to new interventions to target the illness.
This study will identify and evaluate relevant biomarkers and structural brain imaging for understanding potential biological illness related mechanisms in medication-naïve subjects with early psychosis before and after initiation of antipsychotic medication
As specified in the VA Uniform Services Handbook, Family Psycho-Education (FPE) treatment must be available to all Veterans with schizophrenia who could benefit, and their family members. This includes those receiving care at Community Based Outpatient Clinics (CBOCs), and at Psychosocial Rehabilitation and Recovery Centers (PRRCs), whether provided on site, by referral, or by telemental health. However, less than 5% of VA medical centers offer FPE. Clearly, a major challenge is to devise ways to deliver mental health treatments and services to Veterans who need them in ways that meet their needs and preferences. The proposed project will compare the use of a website to deliver FPE to that of in-person delivered FPE. The findings could have profound implications for the VA's ability to improve the reach, use, appeal, and effectiveness of FPE for Veterans with schizophrenia, by using an e-health model that facilitates family involvement.
The mortality rate among people with Serious Mental Illness (SMI) is 2 to 3 times that of the general population, meaning that those with a serious mental illness die, on average, 25 years earlier than those without an SMI. These deaths are largely attributed to preventable medical conditions, many of which are more common in the SMI population. The "Bridge" intervention is a peer navigator model that was developed to target factors that negatively impact healthcare access, utilization, and outcomes among individuals with serious mental illness (e.g., severe mood disorders and psychotic disorders). This intervention targets male and female, adult consumers across races/ethnicities and has been utilized by Pacific Clinics (Southern California's largest behavioral healthcare agency) and the Department of Mental Health of Los Angeles County to improve the health and quality of life for their consumers. Investigators will test the comparative effectiveness of a peer navigator intervention (the Bridge) to treatment as usual. The Bridge navigator intervention is designed to teach SMI consumers the skills to engage health care providers and to overcome motivational deficits in order to improve their health and healthcare use. The specific aims of this application are: 1. To use randomized methods to examine the effectiveness of the Bridge intervention on the health care utilization, satisfaction with care, health status, and health care self-management for a sample of individuals with severe mental illness receiving public mental health services in the community; 2. To use randomized methods to examine the effectiveness of the Bridge intervention on psychological and social well-being for a sample of individuals with severe mental illness receiving public mental health services in the community. 151 participants in an Full Service Partnership (FSP) clinic operated by Pacific Clinics were recruited to participate in an approximately 24-month long study of Bridge navigation. Participants will be randomly assigned to either treatment as usual (waitlist) or immediate intervention with the Bridge. Participants in both groups will complete three assessments (baseline, 6 months, 12 months) and statistically compared over time. Staff stakeholders (n = 20) will also be interviewed at baseline and every three months of the study in order to ensure that the intervention is being implemented appropriately.
Smokers with serious mental illness including those with schizophrenia and bipolar disorder infrequently attempt and attain sustained smoking abstinence and have a 25-year shorter lifespan due to smoking-related illness. This study will examine whether reducing the nicotine content of cigarettes to non-addicting levels is a viable method of reducing smoking in smokers with serious mental illness. Smokers will be randomized to one of two experimental conditions: 1) very low nicotine content (VLNC) cigarettes or 2) normal nicotine content (NNC) cigarettes. Participants will be assessed for patterns of tobacco use, biomarkers of exposure, subjective responses (e.g., satisfaction, craving, withdrawal symptoms), psychiatric symptoms, cognitive performance, smoking cue reactivity and smoking topography.
This randomized, double-blinded, placebo-controlled study will investigate the safety, tolerability, and pharmacokinetics of multiple doses of RO5545965 administered orally to psychiatrically stable patients with schizophrenia receiving risperidone.
