Filter by:The purpose of this research study is to compare the "real-world" effectiveness of two FDA-approved and widely used long-acting injectable antipsychotic medications (paliperidone palmitate and haloperidol decanoate) in patients with schizophrenia or schizoaffective disorder who are expected to benefit from the improved medication compliance associated with injectable medications. The goal is to evaluate the effects of the medications on outcomes of importance to patients (relapse, symptoms, adverse effects, functioning) as well as policy makers (all of the above plus costs).
The benefits and harms of antipsychotics are relatively well studied in adults. However, there is a lack of scientifically valid studies regarding the benefits and harms of antipsychotics in children and adolescents with psychosis. The main objective of the TEA trial is to compare the efficacy and adverse reactions of two antipsychotics (quetiapine versus aripiprazole) in children and adolescents between 12-17 years of age with psychotic symptoms on psychopathology, cognitive deficits, and daily functioning. Furthermore, the trial will focus on adverse reaction profiles of the two antipsychotics as well as early predictors of later sustained clinical effects of these antipsychotics.
This study will provide information regarding dopamine D2/D3 occupancy related with clinical/adverse effects in older people with schizophrenia and schizoaffective disorder. The results of this study will also show an appropriate dose range in order to evade undesirable adverse effects while deriving therapeutic effects, which will directly serve to guide physicians in clinical practice. Furthermore, the findings of this study will elucidate mechanisms underlying older people's increased sensitivity to antipsychotic drugs. In addition, the contribution of D2 and D3 in mediating antipsychotic response will be contrasted, using 2 radiotracers, which has never been tested in an older population. The hypotheses are as follows: First, clinical response (i.e., a ≥ 20% decrease in the Brief Psychiatric Rating Scale total score) will be achieved in older patients with occupancy that is lower than the threshold of 60% in historical young controls. Second, prolactin elevation and EPS will be detected in older patients with occupancies that are lower than the thresholds of 72 and 78% reported in historical young controls. Third, dopamine D2 receptor occupancy will be inversely correlated with subjective well-beings. Fourth, the binding potential and receptor occupancy will be at least 20% lower with [11C]-(+)-PHNO than with [11C]-raclopride in the caudate/putamen. Fifth, the binding of [11C]-(+)-PHNO in the globus pallidus will be higher than that of [11C]-raclopride.
This study will investigate adjunctive pregnenolone for cognitive symptoms and negative symptoms in patients with schizophrenia and schizoaffective disorder.
This is a Congressionally mandated study. In the original study, 16 demonstration programs provided care coordination services to beneficiaries with chronic illness in Medicare's fee-for-service program. A five-year CMS-funded study tested whether the programs can improve patients' use of medical services, improve patients' outcomes and satisfaction with care, and reduce Medicare costs. The study also assessed physicians' satisfaction with the programs. In 2008 Congress extended the project for two of the original programs--Mercy Medical Center - North Iowa and Health Quality Partners in Pennsylvania--and they will enroll Medicare beneficiaries and provide care coordination services into the spring of 2010.
Atypical antipsychotic medications, such as olanzapine, cause metabolic side effects, including weight gain, extra fat around the middle of the body, high blood sugar, and high cholesterol. One of the mechanisms by which these medications may cause these effects is by reducing plasma melatonin. This study is a pilot project to evaluate 1) the effect of olanzapine on melatonin secretion levels and 2) the effect of melatonin on olanzapine-induced changes in melatonin secretion in patients with schizophrenia, schizoaffective, or bipolar disorder.
Our overall aim is to determine if the administration of guanfacine in combination with aripiprazole, olanzapine, quetiapine, and/or risperidone is significantly more effective than any of those medications alone in treating some of the cognitive impairment in schizophrenia.
The current study aims to develop and evaluate a practical, short-term support and education program for relatives of individuals with schizophrenia. This program has been developed to maximize efficiency and effectiveness in the following ways: 1. The intervention specifically targets those factors empirically demonstrated to improve family functioning and well being. Specifically, this pilot intervention aims to: a) increase relatives’ knowledge about schizophrenia spectrum disorders; b) help families attribute distressing behaviors of their ill relatives more accurately, by helping them to distinguish behaviors that are directly related to the illness from personality characteristics; c) improve attitudes towards the patient and reduce stress in interactions with the patient; d) encourage problem-focused coping strategies; e) reduce burden; f) provide opportunities for relatives to expand their social support network; g) help families learn about and utilize community resources. 2. The program involves both individual and multifamily group components, in order to reap the benefits of both formats. Specifically, multifamily psychoeducation groups (involving individuals from several different families) tend to be more economical and allow participants to learn from each other, increase their social support networks, and reduce feelings of stigma. In contrast, individualized programs can target the specific needs of participants.
Patients suffering from Schizophrenia and their families often suffer from poor care because of ignorance about the disorder especially in economically developing countries. Although antipsychotic medication is effective in reducing relapse rate, 30-40 percent of patients relapse within one year and 40-60 percent relapse within 2 years after discharge from 1st hospitalization even if they are receiving maintenance medication. Although antipsychotic medications are the mainstay of the treatment for schizophrenia, patients with schizophrenia benefit more from combined use of antipsychotic drugs and psychosocial treatment than pharmacotherapy alone in delaying or preventing relapse or reducing hospital days. It is also less costly than standard treatment and suitable for psychiatric rehabilitation. Although there are now a number of studies from western countries and a randomized controlled trial from china which have led to increase enthusiasm about psychosocial treatment for schizophrenia but question remains about comparative benefit of treatment methods and additional methods of multiple treatment. In developing countries there is need for further studies in which integrated treatment of pharmaco-therapy and psycho-education is instituted and compared with treatment as usual. Realizing the need for maintaining the compliance and continuity of treatment, department of psychiatry has started a program called Supervised Treatment of Outpatient Schizophrenia. This study aims to evaluate the effectiveness of Supervised Treatment versus the usual care provided in the outpatient.
Many persons with schizophrenia have difficulty getting and keeping a job. This study is designed to compare the benefits of four sessions of motivational interviewing or illness education in increasing employment rates accruing from participation in supported employment.
