Schizophrenia is characterized by psychosis (loss of contact with reality), hallucinations (false perceptions), delusions (false beliefs), disorganized speech and behavior, flattened affect (restricted range of emotions), cognitive deficits (impaired reasoning and problem solving), and occupational and social dysfunction. The cause is unknown, but evidence for genetic and environmental components is strong. Symptoms usually begin in adolescence or early adulthood. One or more episodes of symptoms must last ≥ 6 months before the diagnosis is made. Treatment consists of drug therapy, cognitive therapy, and psychosocial rehabilitation. Early detection and early treatment improve long-term functioning.
