Dissociative fugue, formerly fugue state or psychogenic fugue, is a dissociative disorder. It is a rare psychiatric disorder characterized by reversible amnesia for personal identity, including the memories, personality, and other identifying characteristics of individuality. The state is usually short-lived (ranging from hours to days), but can last months or longer. Dissociative fugue usually involves unplanned travel or wandering, and is sometimes accompanied by the establishment of a new identity. 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 fugue, previous memories usually return intact. Because of this, there is not normally any treatment necessary for people who have been in fugue states. Additionally, 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 other psychiatric conditions such as dissociative identity disorder, delirium, or dementia. Fugues are usually precipitated by a stressful episode, and upon recovery there may be amnesia for the original stressor (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.

A doctor may 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 carefully reviews symptoms and does a physical examination to exclude physical disorders that may contribute to or cause memory loss. A psychological examination is also done.
