Multiple personality disorder usually presents with associated symptoms rather than main features of the disorder, therefore it is necessary for the clinician to keep it in mind as a diagnostic probability and to know its various presentations and associated symptoms in order to elicite it. We observed during long term evaluation of four cases presenting as pseudopsychosis that they had multiple personality disorder with long term histories of dissociative symptoms. It was only a time-limited periode of crisis caused by the underiying chronic psychopathology. Patients presenting with a single dissociative symptom, a dissociative disorder, a severe acute dissociative syndrom with regressive features of a dramatic and therapy-resistant conversion symptom should be evaluated for other dissociative symptoms and especially for chronicity. In our experience, one of the presentations of multiple personality disorder in our culture is pseudopsychosis (hysterical psychosis), a type of crisis situation in this context.
