Filter by:The primary aim of the study is to test the efficacy of a novel cognitive remediation intervention that targets working memory-related functions. To accomplish this goal, 80 volunteer patients with schizophrenia will be enrolled and randomized to either a cognitive remediation condition that targets working memory or a computer skills training intervention that teaches computer applications. In both conditions participants will receive computer training three times a week for 4 months. The investigators hypothesize that patients who receive the cognitive remediation intervention will demonstrate significantly greater change on neuropsychological measures of working memory and executive abilities than patients who receive the computer skills course. In addition, the investigators hypothesize that the intervention-induced cognitive change will be associated with concurrent improvements in functional capacity and psychosocial functioning in the community. A second study goal is to examine the stability of the intervention-induced changes in cognition. Cognition and psychosocial functioning will be reassessed 4 and 8 months after treatment termination to examine the stability of treatment effects and to assess whether a less intense maintenance training (once a week sessions) provides any additional benefit to participants. Lastly, this study will examine in an exploratory manner whether there are individual differences in treatment response. The Val158Met polymorphism of the COMT gene has been found to be associated with working memory and prefrontal dysfunction in schizophrenia. The study will test whether the COMT polymorphism is predictive of response to cognitive remediation.
The purpose of this study is to evaluate the efficacy and safety of long acting injectable (LAI) risperidone and oral risperidone treatment on participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self) or schizoaffective disorder (a mixed psychiatric disorder relating to a complex psychotic state that has features of both schizophrenia and a mood disorder such as bipolar disorder).
The purpose of this study is to find out how effective lifestyle modification group therapy is on reducing body weight when compared to usual care in individuals with schizophrenia and/or schizoaffective disorder.
The purpose of this study is to assess the potential pharmacokinetic (absorption, distribution and excretion of the drug by the body) interaction between, and the safety of, topiramate and risperidone administered in combination in patients with a history of either bipolar spectrum or schizoaffective (bipolar type) disorders as defined by DSM-IV criteria.
Obesity and physical inactivity have reached epidemic proportions, resulting in increased rates of a variety of chronic diseases, increased risk of death, and substantial health care costs. Individuals with serious mental illness are even more likely to be overweight or obese, which contributes to the high rate of co-morbid medical disease and early mortality found among this population. Specific individual and group-based psychoeducational interventions have repeatedly and consistently been shown to help adults with serious mental illness improve their weight. However, these require substantial time from mental health clinicians, and frequent visits by patients to mental health clinics. This creates challenges for patients who may need to travel to a medical center that provides these services, and who often have limited transportation options. It is likely that these barriers can be addressed with a computerized, web-based intervention focused on diet and exercise education, and tailored for veterans with serious mental illness. Web-based systems can deliver content that is intensive, engaging, and tailored to the needs and preferences of specific patients. Web-based systems can be delivered using computers at community-based outpatient Clinics or other settings in the community. The objective of this project is to develop and evaluate the effectiveness of a web-based intervention to help patients with serious mental illness lose weight.
The study aims to examine the combined effects of delta-9-tetrahydrocannabinol (∆-9-THC or THC) and iomazenil on thinking, perception, mood, memory, attention, and electrical activity of the brain (EEG). THC is the active ingredient of marijuana, cannabis, "ganja", or "pot". Iomazenil is a drug that works opposite to drugs like valium. The purpose of this study is to determine whether the administration of iomazenil will alter the effects of THC.
This is a 12-week, randomized, double-blinded, placebo-controlled trial of telmisartan 80 mg/day as an adjunctive to clozapine or olanzapine therapy, in 70 schizophrenia subjects to examine telmisartan's effect on glucose metabolism, weight, food intake, resting energy expenditure, and body composition. In addition, the study will examine insulin's effects on psychopathology and cognition. Potential subjects will be identified by their clinicians at the Freedom Trail Clinic, or Massachusetts General Hospital. Approximately 70 subjects will be enrolled.
This is a randomized pilot study of an intervention based on principles of Cognitive Behavioral Therapy (CBT). This intervention is the Health Dialogue Intervention (HDI) and will be compared to a traditional medical model of psychoeducation known as Team Solutions (TS) for first-episode schizophrenia patients. Outcomes include the acceptance of HDI and TS, compare adherence attitudes at the end of the treatment intervention, and to compare the time until the first episode of nonadherence.
Patient participation is a central concept in Norwegian health policy. It is mandatory in hospitals and emphasised as one of the most prioritised areas by the Government. Studies from Norway have repeatedly found that patients who seek help in community mental health centres ("DPS") are dissatisfied with the information they receive and about their possibility for real influence in their treatment. One way to improve individual patient participation might be to give patients information before they start their treatment. This can be done as group based patient education to reduce the resources needed. Furthermore, as there are waiting lists for treatment, such introduction seminars could be held while patients are waiting to use this time in a meaningful way. The present study therefore aims at testing the effect of an introduction seminar for patients on waiting list in a community mental health centre.
The investigators have developed an intervention called Behavioral Treatment of Smoking Cessation in SPMI (BTSCS), an innovative intervention that supplements pharmacotherapy and education with contingency management and a multifaceted behavioral group treatment program that lasts for three months (24 group meetings). BTSCS is designed to address the cognitive, motivational, and social support problems characteristic of people with SPMI. The investigators propose to conduct a randomized trial for persons with SPMI that compares (1) BTSCS: a 6-month manualized smoking cessation program adapted from an effective substance abuse treatment program for this population to (2) StSST: a standard manualized smoking cessation program which reflects current best practices.
