The purpose of this study is to determine if Ending Self-Stigma (ESS), a 9-session group intervention designed to assist veterans with serious mental illness to develop skills (SMI) to effectively cope with stigma and minimize the internalization of stigmatizing beliefs and stereotypes, is more effective in reducing internalized stigma and its associated effects than an active comparison group.
The primary objective of this study is to evaluate the long-term safety and tolerability of paliperidone palmitate in Japanese patients with schizophrenia. Secondary objectives of this study are to: explore the efficacy on symptoms of schizophrenia and the maintenance of treatment effect; explore the pharmacokinetics of paliperidone palmitate through sparse pharmacokinetic sampling.
The etiology of schizophrenia remains unclear In recent one decade, hypofunction of N-methyl-D-aspartate (NMDA) receptor has been implicated in the pathophysiology of schizophrenia. Hence, enhancing NMDA neurotransmission was considered as a new approach for schizophrenia treatment. To date, refractory schizophrenia (particularly clozapine-resistant) is still a difficult clinical issue. However, the effect of NMDA treatment in refractory schizophrenia is still unknown. Therefore, the primary goal of this study is to investigate the efficacy and safety of NMDA adjuvant therapy in refractory schizophrenia, and to identify the predictors for treatment response to NMDA enhancers.
The purpose of the study is optimising current treatments in schizophrenia and explore novel therapeutic options for schizophrenia. The study intends to both address basic, but so far unanswered, questions in the treatment of schizophrenia and develop new interventions. It is expected that the project will lead to evidence that is directly applicable to treatment guidelines, and will identify potential mechanisms for new drug development.
Schizophrenia is a mental health problem usually starting in the late teens/early twenties, and often lasting many years. The standard medication ('antipsychotics') for this problem is usually helpful, and if taken continually can keep people well, reducing the likelihood of further episodes. However, in up to one in three people with schizophrenia, the illness does not show much improvement with antipsychotic medication. For some of these 'resistant' illnesses, one particular antipsychotic, clozapine, can work well, but one disadvantage is the risk of a severe blood side effect which means that regular blood testing is necessary. If the response to clozapine treatment is disappointing, there is some evidence that adding another antipsychotic can sometimes produce more improvement. However, it seems that the added antipsychotic may need to be taken by the person for at least 10 weeks in order to work well. The investigators plan to test carefully the possible benefits and problems when the antipsychotic amisulpride or a dummy tablet ('placebo') is added to clozapine for 12 weeks in people whose schizophrenia illness has not been helped much by any antipsychotic medication on its own, and who are now taking clozapine, but again with not much improvement. The investigators have chosen amisulpride because its pharmacological action may be complementary to that of clozapine, and also it is less likely than some other antipsychotics to compound some of the characteristic side effects of clozapine, such as sedation, weight gain and other metabolic problems. Adjunctive amisulpride or placebo will be randomly assigned. The investigators expect that adding amisulpride will be more likely to cause an improvement than adding placebo. But the investigators should learn more about the risks and side effects of combining these two medications. Also, the investigators should gain a greater understanding of the possible benefits of adding another antipsychotic to clozapine in relation to particular problem symptoms, and a person's ability to live and work in the community.
The purpose of this study is to validate that SULT4A1-1 status stratification improves responses to atypical antipsychotics in schizophrenia and to extend these findings into bipolar disorder.
Persons with serious mental illness are at increased risk of cardiovascular disease. The goals of this study are to test a treatment, Life Goals Collaborative Care to help promote health behavior change and to get feedback from patients and providers on what is needed to help better coordinate and physical and mental health care of these patients.
This is a multi-site, open-label fixed-flexible dose long-term study of asenapine in participants with schizophrenia. Participants in this study consist of schizophrenia with residual subtype or receiving high dose/multiple antipsychotic drugs, treatment refractory, or elderly participants with schizophrenia. The treatment period is up to 52 weeks.
The prevalence of metabolic syndrome(MS) among pt's with schizophrenia has been reported to be high, ranging from 24 to 43% in males and 27 to 52% in females. Schizophrenic patients with MS have an increased incidence of DM, coronary heart disease and increased mortality from cardiovascular diseases. Central adiposity is highly correlated with the presence of hypertension, coronary heart disease, type 2 diabetes, and increased mortality risk. Waist circumference(WC) is a better indicator of abdominal obesity and a better predictor of CVD than either BMI or waist-to-hip ratio. However, currently there is no standard location for the measurement of WC. Objectives: 1. To compare the magnitude of WC measured at 3 sites ( immediately above the iliac crest, midpoint between the lowest rib and the iliac crest , umbilical level) in males and females. 2. To examine the correlation of WC with Triglyceride, cholesterol, HDL, LDL and glucose.
