Active clinical trials for "Schizophrenia"

Assess the efficacy of a new drug (a receptor agonist that modulates the glutamatergic activity) in the treatment of schizophrenia. The primary objective of this study is to determine if a mGlu2/3 agonist dosed for 28 days is superior to placebo in the treatment of patients with schizophrenia as measured by the Positive and Negative Symptom Scales (PANSS) total score.

This study will determine the effectiveness of cognitive enhancement therapy (CET) in treating cognitive abnormalities in people experiencing the early stages of schizophrenia.

A Placebo Controlled Study For Patients With Schizophrenia

The purpose of this study is to evaluate the safety and effectiveness of citalopram (Celexa) for the treatment of depressive symptoms in middle-aged and elderly patients with schizophrenia.

This study will evaluate a family intervention program for individuals with bipolar disorder, schizophrenia, or schizoaffective disorder and co-occurring substance use disorders.

The purpose of this study is to evaluate the long-term safety of SM-13496 in patients with schizophrenia.

The specific aim of this study is to determine whether the new, long-acting, form of risperidone, Risperdal Consta, improves the ability of schizophrenia patients to benefit from skills training. The hypothesis guiding this study is that Risperdal Consta, by improving verbal memory, will improve the ability to benefit from skills training interventions among schizophrenia patients. The primary objective of this study is to compare patients on Risperdal Consta to patients on other atypical antipsychotic medications in terms of their ability to benefit from skills training interventions. A secondary objective of this study is to determine whether patients taking Risperdal Consta improve in other areas of cognitive functioning and social functioning.

The purpose of this research study is to determine whether a new drug for schizophrenia is better for the maintenance treatment than a standard drugs currently prescribed. The new medication is called quetiapine and it will be compared with a standard medication called haloperidol decanoate. The study will determine if quetiapine causes fewer problems than haloperidol with side effects such as stiffness and restlessness and whether it costs the VA more or less to treat patients with quetiapine. In addition, blood samples will be collected every three months to determine if certain chemicals in the blood can influence the outcome of the subjects' illness.

The purpose of this study is to: To examine wether adjunctive atomoxetine is more effective thank placebo for neuropsychological measures of reaction time, motor speed, psychomotor speed, sustained attention, learning and memory, working memory, and executive functioning. To determine the effect size of atomoxetine on these neuropsychological measures for follow-up studies. To determine if atomoxetine has short-term benefits for improving weight gain and other metabolic abnormalities associated with antipsychotics.

The study investigates the use of Atomoxetine in combination with exercise and a diet support group (Weight Watchers)to treat weight gain associated with Olanzapine or clozapine. All patients must be adults who have been diagnosed with Schizophrenia or Schizoaffective Disorder.
