STUDY PURPOSE: To study whether patients who have schizophrenia or schizoaffective disorder and are randomly assigned to switch to aripiprazole prior to participation in a brief vocational skills training (VST) will have improved cognitive functioning and learn more in VST than those randomly assigned to stay on olanzapine. There is evidence that VST is important in improving role functioning for schizophrenia patients, however, cognitive impairments limit the ability of some patients to benefit from skills training approaches. Patients switched from olanzapine to aripiprazole improve in terms of verbal learning and verbal learning has been shown to be a strong predictor of community outcome. It is unclear whether the cognitive benefits of switching to aripiprazole extend to improve learning of vocational skills.
This preliminary study aims to investigate the mechanism of higher rates of type 2 diabetes mellitus in patients with schizophrenia. As part of the study, we collect neuroendocrine-immune data on patients with first episode, treatment naive psychosis, patients with newly diagnosed schizophrenia and normal healthy controls. Regardless the treatment status, we collect the same neuroendocrine-immune data on the participants after 2 months.
This study proposes to examine the effect of atomoxetine on quality of life and negative symptoms such as social withdrawal, lack of interest in things, lack of thought content, flat emotions, slowed body movements and lack of drive and motivation in patients with schizophrenia or schizoaffective disorder. This study also examines the safety of using atomoxetine along with the conventional antipsychotic in these patients.
The overall goal of this study is to determine the efficacy and tolerability of three atypical antipsychotic medications (risperidone, olanzapine, and quetiapine) in the treatment of adolescents with psychosis. It is hypothesized that the three medications will be equally effective in reducing the symptoms of psychosis.
This study will determine the effectiveness of treatment with glycine or d-cycloserine in addition to a normal antipsychotic regimen in improving negative symptoms and cognitive impairments in patients with schizophrenia.
The purpose of this study is to determine the effectiveness of adding dual focus 12-step self-help groups to standard treatment to improve behavioral outcomes for patients dually diagnosed with substance abuse and psychiatric disorders.
The purpose of the study is to evaluate the maintained effectiveness of long-acting injectable risperidone (RISPERDAL® CONSTA™) compared with the previous treatment with oral olanzapine in non-acute subjects with schizophrenia or schizoaffective disorder considered in need of a therapy change.
The purpose of this study is to evaluate the long-term efficacy and safety of galantamine in patients with Alzheimer's disease.
