Schizophrenia is a psychiatric disorder that is a persistent, usually chronic, major mental illness, the most severe form of psychosis, characterized by a fragmentation of the basic personality, thinking, emotions, and behavior, and a dissonance between mental activity and the environment, most often in young adults, which in turn affects behavior and emotions. The main sign of schizophrenia is thought to be the fragmentation of basic thinking structures and cognition. This dissociation is believed to result in impaired thought forms and the inability to distinguish between internal and external experiences. Individuals with schizophrenia may express hallucinations themselves or, alternatively, others may notice that their performance is influenced by hallucinations. Patients may also express apparently delusional beliefs.
