Schizoaffective disorder is a mental condition that causes both a loss of contact with reality (psychosis) and mood problems.
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.
The symptoms of schizoaffective disorder are different in each person. Often, people with schizoaffective disorder seek treatment for problems with mood, daily function, or abnormal thoughts.
Psychosis and mood problems may occur at the same time, or by themselves. The course of the disorder may involve cycles of severe symptoms followed by improvement.

Talk therapy can help with creating plans, solving problems, and maintaining relationships. Group therapy can help with social isolation.
Support and work training may be helpful for work skills, relationships, money management, and living situations.
People with schizoaffective disorder have a greater chance of going back to their previous level of function than do people with most other psychotic disorders. However, long-term treatment is often needed, and results can vary from person to person.
Complications are similar to those for schizophrenia and major mood disorders. These include:
