A broad term used to describe symptoms of certain mental health problems. Symptoms may include delusions or hallucinations or other loss of contact with reality. People with psychosis are described as psychotic. In common usage, psychotic often is used in the same way as the word crazy, and thus can be offensive and inaccurate. Use the words psychotic and psychosis only when they accurately describe a medical experience. Avoid using psychotic to describe a person; instead refer to a person as having a psychotic condition or psychosis. Avoid using the terms colloquially.
