The primary symptoms of psychosis include hallucinations (experiencing things others do not experience), delusions (a false belief or an incorrect inference about reality that is firmly sustained despite the fact that nearly everybody thinks the belief is false or proof exists of its inaccuracy), and bizarre behavior, as well as strange or incoherent speech. Psychosis may also be referred to as a thought disorder or perceptual disturbance and includes behaviors and symptoms that may be associated with several DSM-5 disorders (e.g., Schizophrenia, Schizoaffective Disorder, Delusional Disorder, Bipolar Disorder, Major Depressive Disorder, etc.). Note: To rate as evidence of psychosis, behaviors and symptoms should not be attributed to substance use or another medical explanation.
