Filter by:Children and adolescents with psychiatric illnesses who are treated with medications called second generation antipsychotic agents (SGA) often gain excessive weight during their treatment with these medications. This weight gain may result in the development of features of the metabolic syndrome or frank diabetes mellitus. There is no consensus on the best way to prevent these complications. The investigators' hypothesis is that daily vitamin D supplementation in these patients will result in decreased levels of the markers of metabolic syndrome with associated reduction in waist circumference.
The primary objective of this treatment review and feedback program is to quantify the risk status for medication adherence in a cohort of Australian patients diagnosed with schizophrenia.
The primary aim of the study is to test the efficacy of a novel cognitive remediation intervention that targets working memory-related functions. To accomplish this goal, 80 volunteer patients with schizophrenia will be enrolled and randomized to either a cognitive remediation condition that targets working memory or a computer skills training intervention that teaches computer applications. In both conditions participants will receive computer training three times a week for 4 months. The investigators hypothesize that patients who receive the cognitive remediation intervention will demonstrate significantly greater change on neuropsychological measures of working memory and executive abilities than patients who receive the computer skills course. In addition, the investigators hypothesize that the intervention-induced cognitive change will be associated with concurrent improvements in functional capacity and psychosocial functioning in the community. A second study goal is to examine the stability of the intervention-induced changes in cognition. Cognition and psychosocial functioning will be reassessed 4 and 8 months after treatment termination to examine the stability of treatment effects and to assess whether a less intense maintenance training (once a week sessions) provides any additional benefit to participants. Lastly, this study will examine in an exploratory manner whether there are individual differences in treatment response. The Val158Met polymorphism of the COMT gene has been found to be associated with working memory and prefrontal dysfunction in schizophrenia. The study will test whether the COMT polymorphism is predictive of response to cognitive remediation.
The purpose of this study is to find out how effective lifestyle modification group therapy is on reducing body weight when compared to usual care in individuals with schizophrenia and/or schizoaffective disorder.
This is a 12-week, randomized, double-blinded, placebo-controlled trial of telmisartan 80 mg/day as an adjunctive to clozapine or olanzapine therapy, in 70 schizophrenia subjects to examine telmisartan's effect on glucose metabolism, weight, food intake, resting energy expenditure, and body composition. In addition, the study will examine insulin's effects on psychopathology and cognition. Potential subjects will be identified by their clinicians at the Freedom Trail Clinic, or Massachusetts General Hospital. Approximately 70 subjects will be enrolled.
The investigators have developed an intervention called Behavioral Treatment of Smoking Cessation in SPMI (BTSCS), an innovative intervention that supplements pharmacotherapy and education with contingency management and a multifaceted behavioral group treatment program that lasts for three months (24 group meetings). BTSCS is designed to address the cognitive, motivational, and social support problems characteristic of people with SPMI. The investigators propose to conduct a randomized trial for persons with SPMI that compares (1) BTSCS: a 6-month manualized smoking cessation program adapted from an effective substance abuse treatment program for this population to (2) StSST: a standard manualized smoking cessation program which reflects current best practices.
The first aim of this study is to determine whether a brain reward center (BRC) deficiency in patients with schizophrenia (SCZ) and cannabis use disorder (CUD) will be normalized when patients are given cannabis or dronabinol. The second aim will serve to further assess the effects of dronabinol on symptoms and medication side effects in this population.
The purpose of this study is to develop a treatment manual for mindfulness meditation to be taught in a group format to individuals with schizophrenia who are engaged in vocational rehabilitation. This study will also determine whether mindfulness meditation is beneficial in terms of improving work function by reducing distressing emotional states and thinking patterns.
There is some evidence that anti-inflammatory treatment may have beneficial effects in schizophrenia and major depression. Cox-2 inhibitors have been tested in preliminary clinical trials for schizophrenia and depression, showing favourable effects compared to placebo (Muller and Schwarz et al 2009). Statins were introduced as cholesterol-lowering agents but have found much wider usage. They are anti-inflammatory agents and thus similar to the Cox-2 inhibitors, which have shown some ability as adjuncts to improve the symptoms of schizophrenia in preliminary studies. The statins are also known to decrease C-reactive protein (CRP), which has been shown in an SMRI-funded study to be elevated in a study of individuals with schizophrenia. Fan et al (2007) demonstrated in a small study in patients with schizophrenia that higher than normal levels of CRP (>0.50 mg/dl) was associated with marked negative symptoms and higher total PANSS scores. Ondansetron is a serotonin (5-HT3) receptor antagonist that is generic and widely used to prevent nausea and vomiting in patients receiving chemotherapy for cancer. GSK did a small study on it as an antipsychotic in the 1980s. Since then, several small studies have suggested that it is effective as an adjunct drug in improving the symptoms of schizophrenia. Statins are widely used in schizophrenia sufferers, particularly those taking second generation antipsychotics, to treat hypercholesterolemia. Both drugs are well tolerated and their side effect profiles well understood. We propose to conduct a feasibility study in patients with chronic schizophrenia to explore the adjunct use of simvastatin and ondansetron on positive, negative and general psychopathology in comparisons to treatment as usual (TAU) over a 12 week period.
The aim of this randomized, double-blind study is to verify the hypothesis that clozapine monotherapy is as efficient as a combination of clozapine and olanzapine therapy in treatment-resistant schizophrenia. A third of schizophrenia patients are non -responders to medications used nowadays. These patients are usually treated with clozapine, but a large proportion of patients don't recover sufficiently. Therefore, these patients are treated with combination of two or more drugs to achieve better treatment results. Until now the scientific evidence has been insufficient to assess the utility of polypharmacy. The aim is to study during 2009 with voluntary patients, if there is any benefit of olanzapine augmentation compared with pure clozapine monotherapy. During the study the patients are not exposed to any additional intervention. The intervention in this study is just to reduce the previously used polypharmacy. Methods: This study lasts for 24 weeks. Participants (30) are randomized in one of two alternative interventions (A or B) before the study. After 12 weeks the intervention arms cross over (from A to B and from B to A). Group B: In addition to clozapine, the participants receive their normal dosage of olanzapine (=the same as on the hospital ward) for 12 weeks, next the decreasing dosage of olanzapine for four weeks and subsequently placebo for 8 weeks Group A: : In addition to clozapine the participants receive the decreasing dosage of olanzapine for four weeks, next placebo for 8 weeks, after that the increasing dosage of olanzapine for four weeks and subsequently the normal dosage of olanzapine for 8 weeks The response for the medical treatment is assessed by Clinical Global Improvement Scale (CGIS) and Global Assessment of Functioning (GAF) -scale. The primary outcomes are GAF and modified CGIS during the parallel phase of the study (the first 12 weeks). The second phase (the last 12 weeks) of the cross-over study is used in the secondary analysis. The use of additional medication (such as benzodiazepines) is used as a secondary outcome measure.
