What the trial is, and whether it could suit you
This study aimed at helping researchers understand how a medication called haloperidol can affect insulin action in the brain. Insulin is a hormone in the body that controls sugar levels in part by lowering the amount of glucose produced by the liver. After eating a meal, insulin levels go up in both the blood and the brain. Insulin in the brain has also been shown to affect the way the brain works and processes information (also known as "cognition"). Haloperidol, is an antipsychotic medication used to treat a variety of disorders such as schizophrenia spectrum disorders, bipolar disorder, and major depressive disorder, but long-term use can have metabolic side effects, like weight gain, type 2 diabetes, and cardiovascular disease. The purpose of this study is to investigate how antipsychotic medications, such as haloperidol, which carries the risk of metabolic changes, might interrupt
