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.
