Dissociative Amnesia

Dissociative amnesia is characterised by extensive but selective memory loss that has no known organic cause (e.g., head injury). Some people cannot remember anything about their past. Others can no longer recall specific events, people, places, or objects, while their memory for other events remains intact. A part of dissociative amnesia is dissociative fugue. Essential feature of this could be an unexpected travel away from home and workplace, the assumption of a new identity, and the inability to recall the previous identity. The fugue usually ends when the person suddenly ‘wakes up’ with no memory of the events that occurred during the fugue. This disorder is often associated with an overwhelming stress.
