Active clinical trials for "Schizophrenia"

The purpose of this study is to evaluate the effectiveness and safety of 3 doses of paliperidone palmitate in treating subjects with schizophrenia.

Ziprasidone is a newer drug intended for the treatment of the symptoms of schizophrenia. This new drug may have an added benefit of being able to help with some of the difficulties in problem solving and memory that many patients with schizophrenia experience. The present study wants to look at ziprasidone and two other drugs frequently used to treat the symptoms of schizophrenia (risperidone and olanzapine) to see if problem solving and memory get better with ziprasidone treatment. Moreover, we will look at symptoms and how they change with treatment.

This is a study with an approved drug for treating type 2 diabetes, for its effects on treating glucose and lipid abnormalities in patients being treated with first or second-generation antipsychotics, and comparison of effects of this drug with another treatment lifestyle modification. Patients who meet inclusion criteria will be treated with pioglitazone for 12 weeks. They will be evaluated for fasting glucose and lipids, glucose-tolerance tests, and neurocognitive battery and tests of verbal memory at baseline and during treatment with pioglitazone.

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.

Prospective, randomized, double-blind, multi-center study on 1 year course and treatment outcome under low-dose typical (haloperidol) vs. atypical neuroleptics (risperidone) in first-episode schizophrenia.

The purposes of this study are: To determine the safety, tolerability and pharmacokinetics of single doses of PF-00184562; and To explore the exposure-response relationship of neuropsychometric and tolerability measures of PF-00184562 compared to olanzapine.

This study will assess the effectiveness of pimozide in enhancing the effects of clozapine in the treatment of schizophrenia.

The primary purpose of this study is to determine whether naltrexone is effective in the treatment of alcohol dependence and abuse in patients with schizophrenia and schizoaffective disorder. Hypotheses are as follows: hypothesis 1: Naltrexone will be more effective than placebo in reducing alcohol use. hypothesis 2: Patients responding to naltrexone by reducing alcohol use will also show reductions in severity of psychiatric symptoms and utilization of inpatient and emergency psychiatric services. hypothesis 3: Severity of psychiatric symptoms and amount of service utilization will correlate positively with alcohol use.

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 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.
