Filter by:This twelve month, open-label study considers the effect of Risperdal (risperidone) versus Zyprexa (olanzapine) on weight gain, physical health, and outcome in a population of those diagnosed with schizophrenia, schizoaffective disorder, major depression or bipolar disorder with psychotic features. This study evaluates symptom response as well as general health indicators such as body mass index, glucose, prolactin, and cholesterol levels at baseline, month (M)1, M3, M6 and M12.
Examines cognitive functioning in patients with schizophrenia or schizoaffective disorder who have been treated with antipsychotic medications. Patients will be assigned to take active medication (Buspar)or placebo along with their prescribed antipsychotic medication for six weeks. Patients' memory and problem-solving ability will be tested before and after medication.
This study supplements patients' current medications with Pravastatin, a cholesterol-lowering medication, to try to improve residual symptoms of schizophrenia, and also to improve cognitive functioning.
The investigators' hypothesis is that oral L-carnosine treatment (as compared with placebo) will enhance cognitive abilities (specifically: measures of attention, executive function, working memory, visuospatial ability and language) in persons with schizophrenia or schizoaffective disorder. Secondarily, they hypothesize that there will be secondary improvements in positive, negative and mood symptoms with L-carnosine treatment. The investigators aim to test these hypotheses by conducting a randomized, placebo controlled, add-on treatment trial of L-carnosine (added to existing antipsychotic treatment) up to 84 recruited subjects with Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) schizophrenia/schizoaffective disorder for a period of 16 weeks. Measures of cognition and psychopathology will be utilized for evaluating primary and secondary outcomes, along with safety assessments.
This study will determine the efficacy of a medication switch to Aripiprazole for the treatment of schizophrenia or schizoaffective disorder in patients with moderate to high symptoms of social anxiety. Specifically the study will test the possibility that a medication switch to Aripiprazole reduces symptoms of social anxiety in this patient population.
The purpose of this study is to examine whether adjunctive galantamine is effective in the treatment of cognitive impairments in patients with schizophrenia.
This is an 18 week (2 weeks run-in, 16 weeks double blind) trial, to determine if an antiviral drug, valacyclovir (Valtrex) is helpful in treating the symptoms of psychosis, a form of a mental disorder.
To assess the effect of risperidone 2 mg daily (QD) on the differential sensitivity of 2 spatial working memory tests (the GMLT and MDR) in non-agitated, drug-naive patients suffering from first-episode schizophrenia/schizophreniform disorder.
The Recognition and Prevention (RAP) Program is conducting a research study comparing an antidepressant, sertraline, alone versus in combination with a second-generation antipsychotic, risperidone, to evaluate their ability to reduce unusual thoughts, suspiciousness and other unusual experiences, to improve reasoning ability, memory, attention and social skills in adolescents.
This study will evaluate the effectiveness of a health management and supported rehabilitation intervention in treating serious mental illnesses in older people.
