Schizophrenia is a mental disorder that makes it hard to tell the difference between what is real and not real.
It also makes it hard to think clearly, have normal emotional responses, and act normally in social situations.
Psychosis - schizophrenia; Psychotic disorders - schizophrenia
Schizophrenia is a complex illness. Mental health experts are not sure what causes it. Genes may play a role.
Schizophrenia occurs in just as many men as women. It usually begins in the teen or young adult years, but it may begin later in life. In women, it tends to begin later and is a milder condition.
Schizophrenia in children usually begins after age 5. Childhood schizophrenia is rare and can be hard to tell apart from other developmental problems, such as autism.
