Cognitive Remediation for Individuals with Psychosis in a Supported Education Setting: A Pilot Study

Cognitive remediation (CR) is a treatment approach that is being increasingly examined as a means through which the cognitive impacts of schizophrenia might be ameliorated. While CR has demonstrated good outcomes when paired with supported employment, little is known regarding how it might be integrated within supported education contexts. In this study CR was examined in a supported education context with 16 individuals with psychosis. The findings indicated that CR aligned well with the academic curriculum with very low attrition, was found useful by students, and showed similar pre-post differences on cognitive measures as those found in previous work

Assessment of strategies for switching patients from olanzapine to risperidone: A randomized, open-label, rater-blinded study

<p>Abstract</p> <p>Background</p> <p>In clinical practice, physicians often need to change the antipsychotic medications they give to patients because of an inadequate response or the presence of unacceptable or unsafe side effects. However, there is a lack of consensus in the field as to the optimal switching strategy for antipsychotics, especially with regards to the speed at which the dose of the previous antipsychotic should be reduced. This paper assesses the short-term results of strategies for the discontinuation of olanzapine when initiating risperidone.</p> <p>Methods</p> <p>In a 6-week, randomized, open-label, rater-blinded study, patients with schizophrenia or schizoaffective disorder, on a stable drug dose for more than 30 days at entry, who were intolerant of or exhibiting a suboptimal symptom response to more than 30 days of olanzapine treatment, were randomly assigned to the following switch strategies (common risperidone initiation scheme; varying olanzapine discontinuation): (i) abrupt strategy, where olanzapine was discontinued at risperidone initiation; (ii) gradual 1 strategy, where olanzapine was given at 50% entry dose for 1 week after risperidone initiation and then discontinued; or (iii) gradual 2 strategy, where olanzapine was given at 100% entry dose for 1 week, then at 50% in the second week, and then discontinued.</p> <p>Results</p> <p>The study enrolled 123 patients on stable doses of olanzapine. Their mean age was 40.3 years and mean (± standard deviation (SD)) baseline Positive and Negative Syndrome Scale (PANSS) total score of 75.6 ± 11.5. All-cause treatment discontinuation was lowest (12%) in the group with the slowest olanzapine dose reduction (gradual 2) and occurred at half the discontinuation rate in the other two groups (25% in abrupt and 28% in gradual 1). The relative risk of early discontinuation was 0.77 (confidence interval 0.61–0.99) for the slowest dose reduction compared with the other two strategies. After the medication was changed, improvements at endpoint were seen in PANSS total score (-7.3; <it>p </it>< 0.0001) and in PANSS positive (-3.0; <it>p </it>< 0.0001), negative (-0.9; <it>p </it>= 0.171) and anxiety/depression (-1.4; <it>p </it>= 0.0005) subscale scores. Severity of movement disorders and weight changes were minimal.</p> <p>Conclusion</p> <p>When switching patients from olanzapine to risperidone, a gradual reduction in the dose of olanzapine over 2 weeks was associated with higher rates of retention compared with abrupt or less gradual discontinuation. Switching via any strategy was associated with significant improvements in positive and anxiety symptoms and was generally well tolerated.</p> <p>Trial registration</p> <p>ClinicalTrials.gov NCT00378183</p

Prevention of metabolic syndrome in serious mental illness

The interaction of lifestyle, socioeconomic status, genetic factors, and treatment with antipsychotic medications likely accounts for the high risk of metabolic syndrome, diabetes, heart disease, and premature mortality in people with serious mental illness. Given the high risk of developing diabetes and cardiovascular disease in persons with serious mental illness, psychiatrists who treat these individuals need to ensure they are familiar with these risks, monitor metabolic parameters in their patients, and educate their patients (and caregivers) about the risks and how to prevent them

Increased caffeine and nicotine consumption in community-dwelling patients with schizophrenia

It is known that people with schizophrenia make poor dietary choices and smoke at alarmingly high rates. There is also anecdotal evidence that they may ingest large amounts of caffeine. However, while smoking habits in this population have been examined, no recent study has quantified caffeine consumption taking into account various dietary caffeine sources unrelated to coffee including convenience foods such as candy bars, chocolate or soft drinks, and compared results to US population data. We employed 24-h diet recalls to assess dietary habits in a sample of outpatients suffering from schizophrenia or schizoaffective disorder. Caloric intake and caffeine consumption were quantified and the relationship to various sociodemographic variables including body mass index (BMI) and dietary quality was examined. 146 patients were recruited. Mean BMI in the sample was 32.7+/-7.9. Patients ingested 3,057+/-1,132 cal on average. Patients smoked at higher rates (59.6% vs. 23.4%, p< or =0.001), higher numbers of cigarettes/day (24+/-14.4 vs. 13.5+/-11.3, t=8.549, p<0.001) and ingested more caffeine (471.6+/-584.6 mg vs. 254.2+/-384.9 mg, t=6.664, p<0.001) than US population comparisons. Caffeine consumption was correlated to the number of cigarettes smoked daily (r=0.299, p< or =0.001), but not to BMI (r=0.134, p=0.107) or dietary parameters such as caloric intake (r=0.105, p=0.207). Community-dwelling schizophrenia patients consume significantly more caffeine and nicotine than US population comparisons. Clinicians should be aware that while a significant proportion of patients are overweight and have poor dietary quality - which merits lifestyle counseling on its own - there is a lack of correlation between those factors and smoking and caffeine intake. Thus, lifestyle modification counseling in all patients should address smoking and caffeine intake concurrently
