Schizoaffective disorder is a mental condition that causes both a loss of contact with reality (psychosis) and mood problems.
Causes, incidence, and risk factors
The exact cause of schizoaffective disorder is unknown. Changes in genes and chemicals in the brain (neurotransmitters) may play a role. Some experts do not believe it is a separate disorder from schizophrenia.
Schizoaffective disorder is believed to be less common than schizophrenia and mood disorders. Women may have the condition more often than men. Schizoaffective disorder tends to be rare in children.
