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 recognize it. We observed during long-term evaluation of four cases of hysterical psychosis (HP), that they had DID with long-term histories of dissociative symptoms. Patients applying for care who manifest a single dissociative symptom, a dissociative disorder, a severe acute dissociative syndrome with regressive features, or a dramatic and therapy-resistant conversion symptom should be evaluated for other dissociative symptoms and especially for their chronicity. In our experience, one presenting form of dissociative identity disorder is a hysterical psychosis, a type of crisis situation in the context of the longitudinal course of the dissociative identity disorder.370497 bytesapplication/pdfen-USArticle
