Brief psychotic disorder

Brief psychotic disorder is a general psychiatric term for any episode of psychosis lasting more than one day, but less than one month, where the patient has no other underlying condition that could cause the symptoms and where the patient returns to normal functioning after the episode.
The condition is very uncommon.  It usually occurs after an extremely stressful but non-traumatic event, such as the death of a close family member.  It can also occur post-partum.  However, in some case, it has no traceable cause.
Once other conditions that cause psychosis are ruled out, treatment is to support the patient until they spontaneously recover.
