Active clinical trials for "Psychotic Disorders"

The major goal of this project is to investigate established insomnia treatments in a schizophrenia population to see if the improved sleep leads to overall better quality of life. In addition, we hypothesize that the insomnia treatment may also lead to observed improvements in other symptoms associated with schizophrenia such as cognitive impairments, obesity, and negative symptoms.

Patients who participated in the previous trial 28130, who were eligible, were entered into this trial. Patients who were randomized to placebo in the previous trial 28130 continued on placebo while patients who were randomized to Org 34517 (SCH 900636), regardless of dose, were titrated to 900 mg Org 34517. Patients in this trial took their study medication for 2 weeks in order to study the safety and tolerability of Org 34517.

The purpose of this study is to look at two doses of long-acting injectable risperidone (Risperdal Consta). The study will use a usual dose of Risperdal Consta (50 mg given every two weeks) or a higher dose (75 mg-100 mg given every two weeks) to see which one is better at improving symptoms of schizophrenia or schizoaffective disorder.

The study attempts to evaluate a histamine analog long used for the treatment of Meniere's disease, betahistine, that shows promise in reversing the antihistaminergic effects thought to be involved in antipsychotic induced weight gain. Hypothesis to be tested: A. Patients who have gained a developmentally inappropriate amount of weight on antipsychotics (AP) will see their weight and BMI decrease with betahistine augmentation as compared to placebo augmentation. B. Betahistine augmentation in AP treated patients will increase levels of satiety in a standardized meal situation and decrease caloric intake as compared to placebo augmentation. C. Metabolic effects of betahistine augmentation in AP treated patients will be reflected in differences in waist circumference, hip circumference and waist hip ratios D. Betahistine augmentation in this population will lead to decrease in fasting glucose-lipid lab values related to the development of metabolic syndrome as compared to placebo augmentation

The purpose of this study is to measure the effectiveness and assess the safety of two dosages of the antipsychotic paliperidone extended-release (ER) in patients who are experiencing an acute episode of schizoaffective disorder.

The purpose of this study is to determine whether individuals with schizophrenia who will take a high dose of the B-vitamins folate, B12 and pyridoxine, may experience improvement in their symptoms.

The objective of the study is to determine whether Panax Ginseng with multiple interactions with key components of brain signaling pathway, can augment the effects of antipsychotics in Schizophrenia. We are primarily interested to examine the actions of Ginseng combined with antipsychotics in improving the ways patients diagnosed with schizophrenia behave in social environment, store, process and retrieve information.

Pilot data indicates that pentazocine decreases manic symptoms in hospitalized individuals. To follow up these initial findings, we plan to conduct a larger, more rigorous, double-blind study. We will examine whether pentazocine, an agent with kappa-opiate activity, decreases manic symptoms.

The principal aim of the project is to conduct an off-label adjunctive clinical trial evaluating varenicline as a treatment for core neurobiological and clinical deficits in schizophrenia, in addition to evaluating for smoking cessation in schizophrenia patients.

The purpose of this trial is to study the effect of adding the omega-3 fatty acid EPA and/or Vitamins E + C to antipsychotic drugs in younger patients with schizophrenia and related psychoses.
