Active clinical trials for "Schizophrenia"

The study evaluates the feasibility of using a 4 week stimulation protocol with the deep TMS H-coils for the treatment of negative symptoms and cognitive deficit in schizophrenia patients

This is a 12 week outpatient study for patients with schizophrenia who are on Clozapine, but continue to experience symptoms. The purpose of this project is to find out if small doses of pimozide (an antipsychotic medication, taken by mouth) will be helpful in reducing symptoms (such as hearing voices, having trouble in organizing your thoughts, lack of interest in life events and social activities), compared to placebo (an inactive substance, "sugar pill"), when added to clozapine in patients with schizophrenia. The participant will be asked to come in once a week to meet with the research staff and study doctor. The participant will continue to see your regular clinician during this study for all normal appointments. The participant will remain on your current medications throughout the study. During the study you will be randomly selected to be put on a small dose of Pimozide or placebo.

Patients with schizophrenia are much more likely to be engaged in smoking and other addictive behaviors, possibly related to biochemical abnormalities in the reward center of the brain. The primary purpose of the present study is to investigate whether switching patients with schizophrenia to a new atypical antipsychotic, aripiprazole, a drug with a novel mechanism of action, will have an impact on smoking behavior.

Standard antipsychotic drug regimens do not fully address the impact of cognitive symptoms associated with schizophrenia. The NMDA receptor has been connected to the pathophysiology of schizophrenia. Memantine is an uncompetitive NMDA receptor antagonist. It is hypothesized that adjunctive therapy with memantine will reduce NMDA receptor hyperactivity, improving signal to noise ratio and thereby improving cognitive symptoms.

The purpose of this trial is to study liquid aripiprazole in patients with stable schizophrenia.

This study will examine the ways in which schizophrenia-related symptoms affect response to a rehabilitation program for people with schizophrenia.

This study is based on the hypothesis that by increasing N-methyl-D-aspartic acid (NMDA) receptor function in the brain and thereby increasing the capacity of the brain to both form new connections and strengthen existing connections, schizophrenic patients may derive both greater and sustained benefit from cognitive retraining.

We hypothesize that symptoms will improve in patients who meet diagnostic criteria for the schizophrenia prodrome when they are prescribed aripiprazole.

Background: Antioxidants are substances that are considered as a defensive material which protects cells from destruction. It is evident that use of food stuff rich in antioxidant will fortify one's ability to encounter with physical & mental disorders. Since, among several potential elucidations, oxidative stress is more likely deliberated as one of the causative factors which give rise to cognitive and functional impairment. This deterioration further result in intricacy in ones thought process as progressive brain changes crop-up schizophrenic unfold. Therefore, this study was conducted with objectives to explore the role of selected antioxidants (vitamin C & E) and to compare the role of both vitamins as an add-on management of schizophrenia .Materials & Methods: One hundred and five patients were selected from department of psychiatry King Edward Medical University Lahore, and assigned into 3 groups by simple random lottery method. For eight weeks, Vitamin C group intervened with 500mg vitamin C tablet once a day, vitamin E group with 600IU vitamin E twice daily and placebo group was given 500 mg paraffin oil capsule daily. PANSS scale was used to assess the symptoms of schizophrenia. Demographic information was collected by structured questionnaire. Dietary habits were assessed by food frequency questionnaire.

The purpose of this study is to develop and evaluate an intervention that adapts Community Reinforcement and Family Training (CRAFT) for families experiencing first episode psychosis and substance use delivered via telemedicine (video conferencing). The intervention aims to improve treatment engagement and reduce distress, and it will be delivered via telemedicine (CRAFT-FT). To assess feasibility of the intervention, family members will complete the sessions and provide feedback to refine the treatment manual. Data on client relatives with psychosis will be collected for preliminary assessment purposes. Client relatives will not complete the research study intervention.
