DROMOMANIA, also fugue state or psychogenic fugue, is a dissociative disorder and a rare psychiatric disorder characterized by reversible amnesia. It is based on an uncontrollable psychological urge to wander. People with this condition spontaneously depart from their routine, travel long distances, might take up different identities + occupations. It does imply a psychological compulsion, usually on one's own and often without one's conscious knowledge, rather than a more generalised desire to travel. A famous case was Jean-Albert Dadas, a Bordeaux gas-fitter, who would suddenly set out on foot and reach cities as far away as Prague, Vienna or Moscow with no memory of his travels. Jean-Martin Charcot defined the "automatisme ambulatoire". The term here is used to describe people who have a strong emotional or even physical need to be constantly traveling and experiencing new places. According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) it is a facet of dissociative amnesia. It might be referred to also as PORIOMANIA, impulsive, aimless wandering, from ancient Greek πορεία (journey) + μανία.
