Filter by:Schizophrenia is a severe mental illness, of psychosis being the most prevalent in society, affecting 1% of the population. The treatment of schizophrenia is basically done with antipsychotic drugs, although other non-pharmacological interventions, such as exercise, a form of treatment seems to be considered. Among the most recommended exercise for the general population, the investigators highlight the aerobic and resistance exercises. However, few studies have reported the positive effect of aerobic exercise in the pathogenesis of schizophrenia. In relation to resistance exercise and concurrent training, it is unknown if the effect in patients with the disease, especially when one considers the junction of the two types of exercises in the same training session (called concurrent training). However, it is known, through clinical studies and animal models, that exercise modifies the brain improves neuroplasticity, the mental condition of the individual frames and reverses neurodegeneration. Associated with improvement in schizophrenia, few clinical trials of aerobic exercise showed improvement in disease symptoms, reducing anxiety and depression, and clinical global improvement. The hypothesis is that the types of proposed training, resistance training and concurrent training can improve clinical symptoms of the disease, and improve the side effects caused by drugs. It is believed that the clinical changes are accompanied by increased serum IGF-1 by resistance training and aerobic training by BDNF.
The purpose of this study is to evaluate the efficacy of brexpiprazole compared with placebo as maintenance treatment in adults with schizophrenia.
People with serious mental illness have difficulty making good use of primary care, and die, on average, years earlier than others in the population. The greatest contributors to this premature mortality are medical illnesses, especially cardiovascular disease and cancer. The Patient Centered Medical Home is a model for reorganizing primary care practice so that healthcare is more effective, efficient, and user-friendly. It has been implemented across VA as the, "Patient Aligned Care Team" (PACT). It is unclear, however, how this PACT model applies to people whose predominant illness is treated by specialists. This is the case for people with serious mental illness (SMI), many of whom receive ongoing treatment at mental health clinics. To achieve optimal health outcomes in the population with SMI, it may be necessary to adapt the PACT model so that it includes approaches that have proven to improve healthcare in this population. This project implements an adapted "SMI-PACT" model, and evaluates its effect on Veterans with SMI.
Only a few intervention studies have also focused on changing patients' negative thoughts and feelings towards the illness and their relationship to the suffering caused by those thoughts, which is evidenced to empower psychosocial functioning and control of distressing thoughts in severe depression and psychotic disorders by using the Mindfulness-Based Stress Reduction program. This controlled trial is designed to test the effects of a mindfulness-based Illness management program (MBPP) for Chinese patients with schizophrenia on their symptom severity, illness insight and psychosocial functioning.
The primary purpose of this study is to evaluate the overall efficacy of aripiprazole intramuscular (IM) depot as acute treatment in subjects with schizophrenia. The secondary purpose is to evaluate the safety and tolerability of aripiprazole IM depot administered every 4 weeks for 12 weeks to adult subjects with schizophrenia.
Approximately 30-60% of all schizophrenia patients who fail to respond to typical antipsychotics may respond to Clozapine. Clozapine has long been considered the "gold standard" within the atypical neuroleptic spectrum, backed by years of clinical experience and research, but uncertainties remain in some aspects of this drug. One such question is the link between dose, blood levels and patient clinical response. The Clozapine therapeutic plasma levels range between 250 - 450 ng/mL creating difficulties in using these results in routine clinical practice. Approximately 30% - 51% of "treatment-resistant schizophrenia" patients do not fully respond to Clozapine, a poorly understood phenomenon. Factors relevant to Clozapine-resistance include co-morbidity, drug misuse, poor adherence, inadequate duration of treatment and inadequate dose/plasma-levels. Pharmacogenetic factors such as different polymorphisms in involved genes may play a role. Pharmacodynamic and genetic data appear important in determining the clinical response to Clozapine. Clozapine-treated patients possessing different 3A4 polymorphisms, may respond differently as compared to other patients having normal 3A4 alleles. Recently, the CYP2D6 has also been involved in this drug metabolic pathway. Population pharmacokinetics of clozapine evaluated with the nonparametric maximum likelihood method. This pharmacogenetic explanation/hypothesis may explain Clozapine- resistance in schizophrenics. The high variability in plasma levels requires a large study in order to be able to determine correlation between clinical efficacy and plasma levels and genotyping. A preliminary study will enable power analysis and adequate determination of sample size.
The purpose of this study is to explore the efficacy of flexibly dosed paliperidone extended-release (ER) in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self) who were previously unsuccessfully treated with other oral antipsychotics.
The purpose of this study is to evaluate the efficacy, tolerability and safety of paliperidone extended release (ER) tablets (between 3 to 12 milligram (mg), once a day) in the prevention of relapse in schizophrenia participants.
- To estimate dopamine receptor occupancy by aripiprazole using computer simulation - To measure dopamine receptor occupancy by aripiprazole in patients treated with the antipsychotics - To validate the simulation result by comparing the receptor occupancy from the simulation with that from the patients
The purpose of this study is to evaluate the use of the drug isradipine for cognitive enhancement in patients diagnosed with schizophrenia and schizoaffective disorder.
