Active clinical trials for "Schizophrenia"

The purpose of this study is to examine treatment practices of adult schizophrenia patients by their own doctors, and to assess patient outcomes when treated with long-acting risperidone injection over a two-year period of observation.

The purpose of the study is to evaluate a new treatment to help patients who have problems because of their use of alcohol. The treatment is called Behavioral Treatment for Alcohol Abuse in Schizophrenia (BTAAS).We are interested in determining whether BTAAS is more effective in reducing use than a supportive control treatment.

This study is a six-week, open label trial of the novel antipsychotic agent, ziprasidone, added to a stable dose of clozapine or olanzapine in 40 diabetes mellitus patients, patients with an impaired fasting glucose or insulin resistance with schizophrenia or schizoaffective disorder. The first two weeks will be a fixed-dose of ziprasidone 40 mg twice a day. During weeks 2-6, the ziprasidone dose may be increased up to 80 mg twice a day.

This study will determine the effectiveness of various combinations of psychosocial therapy and risperidone treatment in improving work or school performance in people with first-episode schizophrenia.

This placebo-controlled study is designed to evaluate the efficacy of glycine, an agonist of the glycine-B co-agonist site of the NMDA receptor, on alcohol consumption and craving as well as negative symptoms in schizophrenia. Glycine will decrease the rewarding action of ethanol and reduce ethanol consumption. Also, glycine will improve negative symptoms and cognitive deficits in schizophrenia.

This study will evaluate the effectiveness of ziprasidone treatment versus treatment with a standard atypical antipsychotic drug in improving insulin sensitivity and reducing excess abdominal fat storage in people with schizophrenia who are at risk for diabetes.

The overarching purpose of the proposed study is to determine Secretin's (RG1068) psychophysiological effects on measures of motor learning, affective, and inhibitory information processing in individuals with schizophrenia. Motor learning will be assessed with a classical eye-blink conditioning procedure, requiring the learning of a reflexive eye-blink response to a weak puff of air to the eye.

The purpose of this clinical research study is to evaluate if Aripiprazole will prove to be effective, safe and well tolerated in the treatment of patients with schizophrenia who are treated in a general psychiatric setting.

The purpose of this study is to evaluate the effectiveness and safety of risperidone, formulated as a long-acting injectable drug, compared with risperidone tablets in the treatment of patients with schizophrenia.

Various studies suggest that patients treated with Olanzapine can experience a substantial weight gain, while no changes have been observed in patients treated with Ziprasidone. Negative consequences on lipid and glucose profiles have also been observed in patients treated with Olanzapine. Most of the available data belong to short-term studies. However, for most clinical trials the primary variable was an efficacy variable, and included the weight assessment as a secondary variable; they also lack a systematic monitoring of some variables that can play a role in weight gain, as the level of exercise, appetite increase, etc. and we have considered of importance their inclusion in this protocol. Previous studies did not assess visceral fat using widely standardized parameters as the waist index, which at certain levels is considered an indicator of the cardiovascular risk, or leptine, highly correlated to the body fat storage. We would like to fit the recently published American Diabetes Association, American Psychiatric Association, American Association of Clinical Endocrinologists and North American Association for the Study of Obesity Antipsychotic, obesity and diabetes mellitus consensus.22 Schizophrenic patients show a 4-fold probability to die as a consequence of cardiovascular problems compared to the normal population. The antipsychotic treatment can contribute to increase this risk favoring weight gain and the appearance of cardiovascular risk factors associated to obesity (blood hypertension, hyperlipidemia, type II Diabetes Mellitus). We intend to obtain a complete cardiovascular risk profile of patients, as well as its change during antipsychotic treatment, including primary cardiovascular risk factors in addition to the analysis of markers that have recently been linked to cardiovascular risk (as reactive protein C). The study will evaluate the risk of hyperglycemia, insulin resistance and Diabetes Mellitus, and will investigate the association between glucose homeostasis abnormalities and weight gain in the treated patients. Likewise, adiponectine, secreted from adipocytes and a possible link between obesity and insulin resistance will be determined; recent studies show an adiponectine decrease in humans with insulin resistance and obesity; furthermore, prospective studies have shown these changes could predict a higher risk of DM development. Changes have been introduced in the complete evaluation of the patient's metabolic and cardiovascular profiles with the advice, and under the coordination of endocrinologists after a complete review of the subject
