Psychosis is a generic term used to describe altered thought and behavior in which the patient is incapable of interpreting his or her situation rationally and accurately. Psychotic symptoms can occur in various medical, neurologic, and psychiatric disorders. Many psychotic reactions seen in medical settings are associated with the use of recreational or prescription drugs. Some of these drug-induced psychotic reactions are nearly indistinguishable from schizophrenia in terms of hallucinations and paranoid delusions.
