Schizophrenia is a severe mental disorder, characterized by profound disruptions in thinking, affecting language, perception, and the sense of self. It often includes psychotic experiences, such as hearing voices or delusions. It can impair functioning through the loss of an acquired capability to earn a livelihood, or the disruption of studies.
Schizophrenia typically begins in late adolescence or early adulthood. Most cases of schizophrenia can be treated, and people affected by it can lead a productive life and be integrated in society.
