By completing this module, you will acquire a solid understanding of investigative techniques used to determine the cause of psychosis in your patient in addition to learning the multi-factorial management plan necessary to treat patients with psychosis. Pharmacotherapy as well as biopsychosocial approaches will be emphasized.
