Schizoaffective disorder

Definition:

Schizoaffective disorder is a mental condition that causes both psychosis and mood problems.

Psychosis means a person has a loss of contact with reality and may have hallucinations (hearing voices or seeing things that are not present) and delusions (false, fixed beliefs). Mood disorder problems may include a very bad or very good mood with sleep disturbances, changes in energy and appetite, disrupted concentration, and poor daily function.

Causes, incidence, and risk factors:

The exact cause of schizoaffective disorder is unknown. Genetics and body chemistry may play a role.

Schizoaffective disorder is believed to be less common than schizophrenia and mood disorders. Women may have the condition more often than men. While mood disorders are relatively common in children, a full syndrome of schizophrenia is not. Therefore schizoaffective disorder tends to be rare in children.
