What causes brief psychotic disorder?
The exact cause of brief psychotic disorder is not known. One theory suggests a genetic link. This is based on the fact that the disorder is more common in people who have family members with mood disorders, such as depression or bipolar disorder. Another theory suggests that the disorder is caused by poor coping skills, as a defense against or escape from a particularly frightening or stressful situation. These factors may create a vulnerability to develop brief psychotic disorder. In most cases, the disorder is then triggered by a major stress or traumatic event. Childbirth may trigger the disorder in some women.
