DID has diagnostic criteria involving memory issues, so does Dissociative Amneisa, and Depersonalization/derealization disorder, as does Other Specified Dissociative Disorder and Unspecified Dissociative Disorder also leaves room for any dissociative symptom that does not fully fit any of the other dissociative disorders.
