Filter by:This study is a feasibility study of a multi-component intervention to enhance healthy living among young people with psychotic disorders, specifically targeting smoking and weight.
This research has been designed to learn whether getting regular and specific feedback about work performance with small rewards for meeting goals helps people to improve their job performance and leads to better work outcomes, improved mental functioning, and better quality of life
The etiology of schizophrenia remains unclear. Schizophrenia patients reveal positive symptoms, negative symptoms, and cognitive impairments. In addition to dopamine system hyperactivity, hypofunction of N-methyl-D-aspartate (NMDA) receptor plays a role in the pathophysiology of schizophrenia. Consequently, enhancing NMDA receptor neurotransmission has been considered as a novel treatment approach. To date, there have been several trials on NMDA enhancers reported. For example, sarcosine (N-methylglycine, a glycine transporter I inhibitor) showed therapeutic effects not only in chronically stable patients but also in acutely exacerbated ones when added-on to antipsychotics. In addition, sarcosine yields excellent safety profiles, in comparison to current antipsychotics. It remains unclear whether NMDA enhancers, such as sarcosine, can serve as monotherapy for schizophrenia. The aims of this project are to examine the efficacy and safety of sarcosine monotherapy for acutely-ill schizophrenic patients, and to compare the effects of 2 grams/day, effective dose, with 1 gram/day, ineffective lower dose.
This study involves a controlled trial of an optimized version of a weight management and physical activity psycho-educational intervention (called MOVE!) with 200 obese and overweight veterans with serious mental illness.
Patients suffering from schizophrenia and schizophrenia spectrum psychosis frequently experience cognitive impairments. Such deficits may affect memory, attention and executive function processes. Many studies have shown that cognitive impairments predict daily functioning. Improvement of these difficulties represents a major component of recovery in such population. Second generation antipsychotics, now first line intervention, have been shown to improve cognitive processes compared to first generation agents. However, more subtle cognitive impairments may still remain. In fact, cognitive impairments is one of the most frequent subjective complaints from patients and their family, even though antipsychotic treatment has been optimized. Very few options are available to clinicians to try to improve such persistent cognitive difficulties. First, cognitive remediation techniques have shown some effectiveness but results are sparse and come from a very small number of studies. It is also not clear if cognitive improvement obtained from such techniques would apply to daily functioning and can be generalized.A second possible intervention would be to add a pharmacological agent able to improve cognition. Modafinil (Alertec) is officially indicated for improving wakefulness in patients with excessive daytime sleepiness associated with narcolepsy. Some empirical data and clinical observations suggest that modafinil could improve alertness and/or cognitive functioning without exacerbating psychotic features in persons with schizophrenia and psychotic disease in the spectrum of schizophrenia. This study aims to (a) assess the effect on cognitive functioning of modafinil as an adjunctive to a second generation antipsychotic in a prospective cohort of thirty patients suffering from schizophrenia and psychosis in the spectrum of schizophrenia. This study will also (b) evaluate the impacts of the addition of modafinil on side effects, psychopathology symptoms and other health parameters (such as weight, metabolic profile, etc.). Our principal hypothesis is that significant improvements will be observed on attention processes without any exacerbation of psychotic symptoms or major emerging side effects. This cross-over placebo-controlled prospective study will include patients with schizophrenia or psychosis in the schizophrenia spectrum according to DSM IV definition, men or women aged over 18 years old, with no item score equal or over 5 at PANSS positive symptoms subscale. At enrollment, all patients will have to experience significant cognitive difficulties with scores equal or lower than Z=-1.00 at Color trail test, Mesulam and Weintraub Cancellation Test, Stroop test or Continuous Performance Test-II. Patients will be exposed to 100mg daily of Placebo or Modafinil for 2 weeks than to 200mg daily for the two following weeks. A two weeks wash out period will then take place before the same sequence will be start again. Patient will thus be exposed one month to placebo and one month to modafinil or conversely, in a random fashion.Assessments will include neurocognitive standardized battery, psychopathological tools (PANSS, CGI, SOFAS, SDS), side effects (UKU, ESRS, DAI), vital signs, anthropometric and metabolic profile.
The purpose of this study is to determine whether cannabidiol, a herbal cannabinoid, is effective in the treatment of acute schizophrenic or schizophreniform psychosis in a placebo-controlled, randomized double-blind study.
This study will determine the effectiveness of the Graduated Recovery Intervention Program, a manual-based individual therapy program, in enhancing the clinical benefit of routine treatment for individuals recovering from their first episodes of psychosis.
Many individuals with schizophrenia smoke cigarettes. Individuals in the schizophrenic population often find it difficult to quit smoking. The purpose of this trial is to determine the safety and effectiveness of bupropion in treating individuals with schizophrenia who smoke.
The purpose of this study is to compare the effectiveness of two antipsychotic medications, Risperdal® Consta® versus Abilify®, over a 2-year treatment period in the long-term maintenance of patients with schizophrenia.
This study is a non-interventional web based registry designed to assess demographic, treatment and outcomes data in patients receiving treatment with long-acting injectable risperidone. One year retrospective data and 2 year prospective data will be collected.
