Fugue state

Dissociative fugue, formerly fugue state or psychogenic fugue, is a DSM-5 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 no longer its own classification or diagnosis as it was in the DSM-IV, but is now a facet of dissociative amnesia according to the DSM-5.
