Antipsychotic use refers to the use of medications that are primarily used to treat psychotic disorders such as schizophrenia, bipolar disorder, and major depressive disorder with psychotic features. These medications work by altering the levels of neurotransmitters in the brain to help reduce symptoms such as hallucinations, delusions, and disorganized thinking. Antipsychotic medications can be classified into two main categories: typical (first-generation) and atypical (second-generation) antipsychotics. Research in this area focuses on understanding the effectiveness, safety, side effects, and long-term outcomes of antipsychotic use in various populations, as well as developing new treatments and improving existing medications. Additionally, research also explores the mechanisms of action of antipsychotic medications and their impact on brain function and structure.
