Active clinical trials for "Psychotic Disorders"

The purpose of this study is: To investigate whether a treatment with quetiapine for six months in patients with first-episode psychosis may be effective in treating depressive symptoms. To investigate whether a treatment with quetiapine for six months in patients with first-episode psychosis may be effective in mania-like symptoms and to evaluate the general efficacy in psychopathology as well as the safety and tolerability of quetiapine.

The purpose of this study is to determine whether Taurine 4g is effective with antipsychotic medication in the treatment of First Episode Psychosis.Taurine may have an effect on cognition and symptoms. We are examining changes in symptoms and cognition over a 3 month period.

This is a randomized, double-blind, placebo-controlled parallel-group, 6-week study, evaluating two dose levels of ACP-104 or Placebo twice a day in patients with schizophrenia who are experiencing an acute psychotic episode.

The overall goal of this project is to improve the treatment of alcohol dependence in patients with serious mental illness (SMI). SMI for this study is defined as any patient with any of the following diagnoses: schizophrenia, schizoaffective disorder, and bipolar type I or type II disorder. Alcohol and other substance use disorders (SUDs) are common among individuals with SMI. SUD comorbidity is associated with many adverse consequences. However, to date, few reports have addressed the efficacy of pharmacological treatments for SUDs in this population. Naltrexone pharmacotherapy is an effective treatment for alcohol dependence, but it has not been systematically applied to the care of patients with SMI. The primary aim of this study is to determine the feasibility of long-acting injectable naltrexone administration in a clinical trial in patients with SMI who also have a diagnosis of alcohol dependence. Secondary aims include providing a preliminary assessment of the tolerability and safety of long-acting injectable naltrexone in patients with SMI who also have a diagnosis of alcohol dependence. An additional aim is to provide a preliminary assessment of the efficacy of long-acting injectable naltrexone in reducing alcohol use from baseline levels.

Veterans with schizophrenia and schizoaffective disorder experience very high levels of disability and poor community outcome. Further improvements in community outcome for patients with these disorders will not occur simply through better control of clinical symptoms. Instead, it will be necessary to find treatments that address the key determinants of poor functional outcome. Evidence strongly suggests that basic (non-social) cognitive and social cognitive deficits are among the key determinants of functional outcome for these illnesses. The primary goal of this 2-year pilot study is to implement and validate a new remediation program for social cognition that is appropriate for veterans with schizophrenia and schizoaffective disorder.

This study will evaluate the safety and efficacy of two dose levels of pimavanserin (ACP-103) compared to placebo in patients with Parkinson's disease psychosis.

An open-label, multi-center, 6-week, sequential cohort study designed to determine the safety and tolerability of two dose ranges of BL-1020 in hospitalized subjects with chronic schizophrenia or schizo-affective disorder

The aim of the study is to investigate the efficacy and safety of aripiprazole in patients with first episode psychosis.

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 clinical trial is to find out how effective low dose oral naltrexone is on reducing body weight when compared to placebo in women with schizophrenia and schizoaffective disorder.
