Filter by:This randomized clinical trial among SMI smokers assessed whether the EDSS with carbon monoxide monitor and health-checklist feedback lead to higher rates of initiation of smoking cessation treatment, days of smoking abstinence and Fagerstrom Dependence scores, compared to use of the EDSS with checklist feedback alone.
The objective of this study is to evaluate the efficacy and safety of cariprazine relative to placebo in the prevention of relapse of symptoms in participants with schizophrenia.
Note: In June 2013, the study design was changed from a randomized controlled study of risperidone + despiramine vs. risperidone vs. placebo to an open label pre-post study of risperidone (or risperidone-like drug) + desipramine. The aims of the study were revised to read: 1. To determine whether participants treated with risperidone in combination with desiprmaine have less alcohol use (fewer drinking days; fewer heavy drinking days) during the final 8 weeks on these medications as compared to pre-baseline. The primary hypothesis is that compared to pre-baseline, participants will demonstrate fewer days of drinking (per week), as well as fewer days of heavy drinking (per week) in the final eight weeks they are taking risperidone and desipramine, as recorded on the Timeline Follow-Back assessment 2. To explore changes in symptoms (of schizophrenia and of depression) in the final eight weeks of treatment with risperidone + desipramine compared to the period before baseline 3. To assess the side effect burden associated with the combination of these two medications in participants. The original aims of the study were: The purpose of this study is to determine whether participants who are treated with risperidone in combination with desipramine have less alcohol use (fewer drinking days; fewer heavy drinking days) than do participants who are treated with RISP with placebo. The primary hypothesis is that compared to treatment with risperidone, participants randomized to a combination of risperidone plus desipramine will have fewer days of drinking, as well as fewer days of heavy drinking. The study will also compare the effects of risperidone as compared to risperidone plus desipramine on participants' symptoms and side effects.
This project tests a model for improving illness self-management among persons who have both serious mental illness and diabetes and will be performed within a primary care setting at a safety net hospital system. The information gained from the randomized trial will be supplemented with reports from participants about their experiences of trying to improve illness self-management. Improvements in self-management should result in a reduction of psychiatric symptoms and improvements in functioning and physical health.
In this study the investigators will recruit patients with the diagnosis of schizophrenia that are taking atypical neuroleptics and that are willing to participate in an exercise and diet program. The investigators will measure weight and abdomen circumference.
Clozapine has been virtually the only psychopharmacological choice in patients with schizophrenia who either did not response to typical neuroleptics or experienced severe extrapyramidal side effects and consequently did not tolerate this medication. There are patients who do not respond to clozapine, and the need to treat these severely ill patients frequently compels clinicians to adopt therapeutic innovations that lack a sound empirical basis. One strategy is the combination of various other somatic treatments with clozapine. Recently, the investigators conduct a preliminary open trial to evaluate the safety and efficacy of fluvoxamine coadministration with clozapine in refractory schizophrenic patients. The combined treatment is well tolerated, and clinical improvement is observed in our patients. And the concomitant fluvoxamine could attenuate the clozapine-induced weight gain and metabolic disturbance. However, the effects of fluvoxamine on the safety and therapeutic efficacy of clozapine need to be further clarified in double-blind study.
The investigators hypothesize that sustained-release DMXB-A-SR (3-2,4 dimethoxybenzylidene anabaseine sustained release) will provide clinical improvement in cognition in patients with schizophrenia who are smokers and who are non-smokers. The study drug may also maintain abstinence from cigarette smoking and improve other symptoms in patients with schizophrenia.
The purpose of this study is changing (improving), after initiating various doses of Paliperidone ER on schizophrenia patients.
Background: - A special brain circuit is important for helping us keeping an eye open for things that are going on around us, even when we are not directly paying attention to them. This circuit seems to work differently in people with schizophrenia than in other people, which may explain specific deficits with broad monitoring observed in people with schizophrenia. Researchers want to compare brain function in people with schizophrenia and healthy volunteers to find out more about how these brain circuits work and affect attention. Objectives: - To study how the brain performs broad visual monitoring in people with schizophrenia. Eligibility: - Individuals between 18 to 55 years of age who have been diagnosed with schizophrenia. - Healthy volunteers between 18 and 55. Design: - Participants will be screened with physical and psychological exams. They will have a medical history. Tests for drug and alcohol use will also be done. - Participants will have two study visits. The first is a training visit and the second is a scanning visit. - At the training visit, participants will practice computer-based tests of focus, memory, and concentration. They will also answer questions about mood, psychiatric symptoms, and smoking habits. - At the scanning visit, participants will perform the computer-based tasks that they practiced at the training visit. They will have magnetic resonance imaging while they perform these tasks.
The purpose of this study is to assess the long-term safety, tolerability and efficacy of oral OPC-34712 as monotherapy in adults with schizophrenia.
