Both global and situationally specific amnesia are often distinguished from the organic amnesic syndrome, in that the capacity to store new memories and experiences remains intact. Given the very delicate and oftentimes dramatic nature of memory loss in such cases, there usually is a concerted effort to help the person recover their identity and history. This will allow the subject to be recovered sometimes spontaneously when particular cues are encountered. Definition
The cause of the fugue state is related to dissociative amnesia, (Code 300.12 of the DSM-IV codes) which has several other subtypes: selective amnesia, generalized amnesia, continuous amnesia, and systematized amnesia, in addition to the subtype "dissociative fugue".Unlike retrograde amnesia (which is popularly referred to simply as "amnesia", the state where someone forgets events before brain damage), dissociative amnesia is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication, DSM-IV Codes 291.1 & 292.83) or a neurological or other general medical condition (e.g., amnestic disorder due to a head trauma, DSM-IV Code 294.0). It is a complex neuropsychological process.As the person experiencing a dissociative fugue may have recently experienced the reappearance of an event or person representing an earlier life trauma, the emergence of an armoring or defensive personality seems to be for some, a logical apprehension of the situation.Therefore, the terminology "fugue state" may carry a slight linguistic distinction from "dissociative fugue", the former implying a greater degree of "motion".
As of September 14, 2017, she was missing again; she was last seen near Sapphire Beach in her home in St. Thomas right before Hurricane Maria. Three months later her mother and a group of friends were searching for her in the Virgin Islands and surrounding areas. Jeff Ingram appeared in Denver in 2006 with no memory of his name or where he was from. After his appearance on national television, to appeal for help identifying himself, his fiancée called Denver police identifying him. The episode was diagnosed as dissociative fugue. As of December 2012, Ingram had experienced three incidents of amnesia: in 1994, 2006, and 2007. Doug Bruce "came to" on a subway train claiming to have no memory of his name or where he was from, nor any identification documents.
