Filter by:Females treated with antipsychotics have higher rates of comorbid metabolic syndrome than males. Despite this, females have historically been excluded from many mechanistic studies due to confounding effects of menstrual cycles. Recent evidence suggests that brain insulin resistance may be an underlying mechanism through which antipsychotics may exert their metabolic side effects. This study seeks to investigate how brain insulin action differs in females according to their menstrual cycle phase, and how a high metabolic liability agent such as olanzapine might interrupt these differential insulin effects. Young healthy females will be given olanzapine and intranasal insulin to test how these treatment combinations change brain processes. Participants will be tested during both the first half of their menstrual cycle (follicular phase) and the second half of their cycle (luteal phase). We predict that intranasal insulin will change MRI-based measures in females, in a comparable way to males, in the follicular phase only. Adding olanzapine will block these effects of insulin in females in the follicular phase. This investigation has the potential to generate new knowledge in an area of significant unmet need. Demonstrating that antipsychotics disrupt brain insulin action, evidenced by inhibition of recognized effects of insulin on neuroimaging measures, will provide novel insights into currently poorly understood mechanisms.
The goal of this observational study is to learn about maternal psychiatric course and infant development in pregnant individuals with severe mental illness, comparing those treated with antipsychotics to those treated with other medications or without medication. The main questions it aims to answer are: 1. Is risk of psychiatric relapse different among individuals who take antipsychotic medication, other medication, or no medication? 2. Are pregnancy and neonatal health outcomes different among individuals who take antipsychotic medication, other medication, or no medication? 3. Do infant behavior and neurodevelopment differ among babies who were exposed to antipsychotic medication, other medication, or no medication in utero? Participants will - complete a psychiatric interview and questionnaires while pregnant; - donate blood from the mother and from the umbilical cord at delivery - have their babies participate in infant behavior evaluations and an EEG procedure. Researchers will compare these outcomes among individuals who were treated either with antipsychotic medication, with psychotropic medications of other classes, and with no medication, to see if psychiatric benefits for the mother and health outcomes for mother and child differ among these three types of treatment.
Interventional, multicenter, open-label, 20 weeks study - To identify efficacy and safety in switching from oral aripiprazole to Abilify Maintena. - To identify efficacy and safety in switching from oral atypical antipsychotics other than aripiprazole to Abilify Maintena
Dopamine receptor occupancy and brain metabolism were measured using positron emission tomography after the administration of aripiprazole. Working memory performance was also measured using N-back task. The investigators explored the relationship between changes in brain metabolism and working memory performance.
Schizophrenia is one of the most severe mental illnesses. The antipsychotic drugs, introduced in early 1950s, have revolutionized the treatment of schizophrenia. About 2 to 4 times as many patients relapse when treated with a placebo as do those treated with antipsychotic drugs. For these medications to be maximally beneficial, they must have an acceptable side effect profile and be taken as prescribed. One untoward effect of many antipsychotic drugs is weight gain. The extent of weight gain apparently varies by drug, which may be because of drugs'differing degrees of action on serotonergic, dopaminergic, histaminergic, and other neurotransmitter systems. Obesity is a threat to health and longevity. Weight gain may also cause patients taking antipsychotic medication to discontinue their medication, which may predispose them to relapse. The pattern of weight gain and metabolic disturbance may vary between the different antipsychotic agents. The underlying mechanism and treatment of these adverse metabolic effects remain unclear. This study will recruit 60 schizophrenic patients during. The patients received monotherapy with atypical antipsychotics (olanzapine, quetiapine, or risperidone). The assessment of metabolic profile will be monitored at baseline, week 2, week 4, and week 8. The measurements include anthropometrical parameters, body composition, glucose level, insulin level, lipid profile, and leptin level. Intra-venous glucose tolerance test will be used to assess the insulin secretion and insulin sensitivity. This proposal broadly aims to discover the underlying mechanism of antipsychotics induced metabolic disturbance and develop efficient treatment to correct it.
