Dissociative fugue, formerly called psychogenic fugue, is one of a group of conditions called dissociative disorders. The word fugue comes from the Latin word for "flight." People with dissociative fugue temporarily lose their sense of personal identity and impulsively wander or travel away from their homes or places of work. They often become confused about who they are and might even create new identities. Outwardly, people with this disorder show no signs of illness, such as a strange appearance or odd behavior. Dissociative disorders are mental illnesses that involve disruptions or breakdowns of memory, conscious awareness, identity, and/or perception. When one or more of these functions is disrupted, symptoms can result. These symptoms can interfere with a person's general functioning, including social and work activities, and relationships.

What Are the Symptoms of Dissociative Fugue? A fugue in progress often is difficult for others to recognize because the person's outward behavior appears normal. Symptoms of dissociative fugue might include the following: Sudden and unplanned travel away from home

Inability to recall past events or important information from the person's life

Confusion or loss of memory about his or her identity, possibly assuming a new identity to make up for the loss

Extreme distress and problems with daily functioning (due to the fugue episodes)

What Causes Dissociative Fugue? Dissociative fugue has been linked to severe stress, which might be the result of traumatic events -- such as war, abuse, accidents, disasters, or extreme violence -- that the person has experienced or witnessed. The use or abuse of alcohol and certain drugs also can cause fugue-like states, such as alcohol-induced "blackouts."

How Common Is Dissociative Fugue? Dissociative fugue is relatively rare. The frequency of dissociative fugue tends to increase during stressful or traumatic periods, such as during wartime or after a natural disaster.
