Filter by:This 12-month study will evaluate the efficacy of aripiprazole lauroxil compared to oral aripiprazole in preventing the re-emergence of psychotic symptoms in patients with a recent onset of schizophrenia.
Treatment with prednisolone can be used as a proof of concept to investigate the possibility of immune modulation as a treatment for schizophrenia. It is expected that daily treatment with prednisolone in addition to antipsychotic treatment reduces psychotic symptoms and improves cognition, as compared to placebo. The investigators propose to investigate the effects of administering the corticosteroid prednisolone versus placebo in addition to standard antipsychotic medication in patients with early stage schizophrenia or related disorders, hypothesizing that a decrease in the overall low-grade cerebral inflammation due to prednisolon treatment will be expressed as a decrease in overall symptom severity., Secondly, addition of prednisolone is hypothesised to slow down cognitive deterioration in recent-onset psychosis patients. Finally, the investigators aim to determine whether indirect immunological parameters of the hypothesised low grade inflammation status in schizophrenia are shifted due to the addition of prednisolone.
The purpose of the study is to determine whether two commonly-prescribed antipsychotic medications (aripiprazole and risperidone) have different effects on brain function and cognition in schizophrenia patients.
Current Canadian Clinical Practice guidelines emphasize the need for effective psychosocial adjuncts to pharmacotherapy for schizophrenia (Canadian Psychiatric Association 2005). This randomized control trial seeks to contribute to the body of evidence supporting psychosocial treatments by assessing the effectiveness of metacognitive training (MCT) and cognitive remediation (CR) at treating the persistent positive and cognitive symptoms of schizophrenia. MCT is a therapy designed to improve patient awareness and insight into the cognitive biases that are frequently seen in schizophrenia; it has been associated with decreased psychopathology (specifically decreased positive symptoms) and improved psychosocial function. CR is a therapy designed to improve performance in a variety of neurocognitive functions such as attention, memory, and executive functioning; it has been associated with improved cognitive and psychosocial functioning. Both MCT and CR will be compared to treatment as usual (TAU) as done previously (Kumar er al., 2010; Moritz et al., 2011). Hypotheses: 1. MCT will produce greater change in delusions (severity and conviction) than CR and TAU. 2. CR and MCT will produce greater change in social/everyday functioning than TAU. 3. CR will produce greater improvement in basic attention and memory measures relative to MCT and TAU. 4. MCT will produce greater reduction on tasks measuring targeted reasoning biases relative to CR and TAU. 5. CR will increase efficiency of functional networks on a working memory task relative to MCT and TAU. 6. MCT will lead to a greater decrease in the neural response to evidence matches relative to CR and TAU.
The purpose of this study is to determine if zonisamide SR will prevent weight gain in schizophrenic subjects who take olanzapine (Zyprexa)
Anticholinergic antiparkinsonian agents often cause side-effects including cognitive impairment, dry mouth, and constipation while they diminish antipsychotic-induced parkinsonian symptoms. The introduction of second generation antipsychotics (SGA) brought fewer neurological side effects. However, anticholinergic coprescription rates are still as high as 12-65% in patients on SGA that are much higher than the incidence of EPS reported in clinical trials (3-20%). This apparently discrepancy is likely explained, in part, by the established tradition of routine use of this medications. Older patients are particularly sensitive to anticholinergic side-effects due to age-related changes in pharmacokinetics and pharmacodynamics. In this study, we will examine the safety and benefits of reducing the dose of a frequently prescribed anticholinergics, benztropine, on cognitive function, extrapyramidal symptoms, and psychotic symptoms in older subjects with a primary psychotic disorder.
The purpose of the study is to investigate the well-being of schizophrenic patients treated with quetiapine XR combined with participation in the integrated care program compared to a treatment with quetiapine XR alone over a period of 18 month
The purpose of this study is to evaluate the safety of risperidone treatment in patients who are overweight and/or obese.
The purpose of this project is to evaluate the efficacy of long-acting risperidone for patients with first episode schizophrenia spectrum who did not improve sufficiently with the first antipsychotic medication they tried during their initial treatment trial.
