Filter by:Environmental risk factors for the development of schizophrenia include infections during the perinatal period or later in life with Toxoplasma gondii (TG) being one of the candidate agents. A recent review (Torrey and Yolken, 2003) on TG in schizophrenia and other serious mental disorder reported higher antibodies to TG in patients compared to controls in 18 of 19 studies, one having been conducted by the investigators group. In a second, independent study on first-episode schizophrenia (n=56) and control subjects (n=32), sera were sampled and standard instruments used to assess diagnoses and psychopathology, respectively to screening controls. For the total sample, contacts with animals during pregnancy and age emerged as a non-significant predictors of TG IgG titers. Means of patients' and controls' TG IgG titers did not differ significantly but variances did; a subgroup of patients' titers reached much higher levels than those of controls. Patients in the high TG IgG subgroup were older (p=0.001), also they were older when psychiatric symptoms appeared, more individuals had regular animal contacts during pregnancy, or rural upbringing including regular animal contact, more consumption of raw meat, and a higher absolute treatment response (all trend levels). Regarding the short term course of patients, the investigators detected decreasing IgG titers in several individuals A power analysis demonstrated that results fell short of significance due to lack of statistical power. Based on the power analysis, the investigators propose an opel label, multicenter study at three regionally different sites within Germany (Halle, Hamm, Heidelberg). The investigators intent to study 173 first-episode patients with schizophrenia, schizoaffective, and schizophreniform disorder and 173 matched controls. The investigators hypothesize that - according to the heterogeneity of the illness - a subgroup of patients will exhibit higher TG IgG titers compared to the remaining patients and to controls; that this subgroup will have had regular contact with animals during pregnancy and early life as well as developmental delays; and that clinical improvement, response to treatment, and subjective well-being will run parallel with TG IgG decrease. Patients shall be assessed on admission to hospital, at discharge and at 6- and 12-month-follow-up with respect to TG antibody titers, symptomatology, neuropsychology, predictors of outcome, quality of life, and neurological soft signs. In controls two assessments shall be performed, 12 months apart. All foreseen assessments will be performed using standard measurement instruments with sound reliability and validity such as the SCID and the PANSS. Exposure to cats, other warm-blooded life-stock, and raw meat will be assessed using a special questionnaire.
Bipolar Disorder (BD) and Schizoaffective Disorder (SA) clients. - determine if after 12 months of treatment with clozapine, the BMI changes with clients who are councelled as usual regarding weight gain while on Clozapine. - determine if after 12 months of treatment with clozapine, the BMI changes with intense, structured councelling about diet and exercise.
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 AIMS study compares a methamphetamine-specific treatment intervention to a treatment-as-usual Functional Family Therapy (FFT) approach for adolescents ages 15 to 19. Adolescents are assigned to one of two treatment conditions: (1) 16 weeks of FFT designed to strengthen family relationships and develop skills for helping the adolescent avoid drug use; or (2) 16 weeks of a combination of FFT and a methamphetamine-specific intervention involving group and individual therapy sessions; Families are assessed using questionnaires and interviews, and adolescents participate in neuropsychological testing, before, during, and after treatment to provide information about family functioning, the adolescent's drug use, the adolescent's peers, and other factors that may contribute to treatment success. Adolescents also provide urine specimens for drug screening at assessment visits. Through a partnership with Oregon Health and Science University (OHSU), adolescents will participate in functional magnetic resonance imaging appointments at the hospital to examine regional brain blood flow during tasks designed to measure impulsivity and risk-taking behaviors. As a treatment development grant, study investigators will study adolescents' acceptance of and response to the newly developed methamphetamine-specific treatment approach.
The purpose of this study is to determine if individuals with serious mental illnesses exposed to a patient-centered computerized tool versus printed educational materials have higher rates of screening for the metabolic side effects of second-generation antipsychotic medications and different patterns of communication with their prescribers about screening.
Primary Objective: To compare added metformin and/or added simvastatin versus no intervention in reducing or eliminating increased cardiovascular risk (as estimated by elevation in non-HDL cholesterol levels) during the treatment of schizophrenia with olanzapine. Secondary Objective(s): To compare added metformin and/or added simvastatin versus no intervention in reducing or eliminating increased cardiovascular risk (as estimated by elevation in triglyceride levels) during the treatment of schizophrenia with olanzapine. To compare added metformin and/or added simvastatin versus no intervention in reducing or eliminating increased cardiovascular risk (as estimated by C-reactive protein levels) during the treatment of schizophrenia with olanzapine
The objective is to find determinants for the subjective and objective burden of informal caregivers to patients who are requiring continued antipsychotic treatment for functional psychoses among factors related to the patient, the health care and support provision system and the informal caregiver him/her-self.
Obesity is increasing at an alarming rate in patients with schizophrenia, possibly in association with the increased use of atypical antipsychotics. In order to address the weight and metabolic syndrome issues, Manhattan Psychiatric Center (MPC) has implemented the Solutions for Wellness and Team Solutions Program. This program is designed to create a supportive, educational and monitoring environment to stabilize both the psychiatric and medical conditions and to prepare patients for independent management of their psychiatric and physical health condition in the community.
This study will evaluate the safety and efficacy of two dose levels of pimavanserin (ACP-103) compared to placebo in patients with Parkinson's disease psychosis.
This study will evaluate the effectiveness of intensive computerized cognitive training in preventing the onset of psychotic disorder and improving adaptive functioning in adolescents at high risk of schizophrenia.
