Risk factorsBy Mayo Clinic staff
Schizoaffective disorder is thought to involve delays or variations in the way a child's brain develops — like in schizophrenia. Genetics plays a role in development of the disorder, and people with relatives who have schizoaffective disorder are more likely to develop this condition. Environmental factors also may be involved.
Factors that increase the risk of developing the schizoaffective disorder include:
- Having a relative who has schizophrenia
- Having a relative who has a mood disorder
- Having a relative who has schizoaffective disorder
