Dissociative fugue
Summary
Dissociative fugue (fjuːɡ), formerly called a fugue state or psychogenic fugue, is a mental and behavioral disorder that is classified variously as a dissociative disorder, a conversion disorder, and a somatic symptom disorder. The disorder is a rare psychiatric phenomenon characterized by reversible amnesia for one's identity, including the memories, personality, and other identifying characteristics of individuality. The state can last for days, months, or longer. Dissociative fugue usually involves unplanned travel or wandering and is sometimes accompanied by the establishment of a new identity and the inability to recall personal information prior to the presentation of symptoms. It is a facet of dissociative amnesia, according to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
After recovery from a fugue state, previous memories usually return intact, and further treatment is unnecessary. An episode of fugue is not characterized as attributable to a psychiatric disorder if it can be related to the ingestion of psychotropic substances, to physical trauma, to a general medical condition or to dissociative identity disorder, delirium, or dementia. Fugues are precipitated by a series of long-term traumatic episodes. It is most commonly associated with childhood victims of sexual abuse who learn to dissociate memory of the abuse (dissociative amnesia).
Symptoms of a dissociative fugue include mild confusion and once the fugue ends, possible depression, grief, shame, and discomfort. People have also experienced a post-fugue anger. Another symptom of the fugue state can consist of loss of one's identity.
A doctor might suspect dissociative fugue when people seem confused about their identity or are puzzled about their past or when confrontations challenge their new identity or absence of one. The doctor reviews symptoms and does a physical examination to exclude physical disorders that may contribute to or cause memory loss.
