Natural History

Amnesia may progress slowly or suddenly, and maybe transient or permanent. The natural history and prognosis depends upon the underlying cause.

In patients with post traumatic amnesia, the extent of injury and duration of loss of consciousness are important prognostic factors in determining the severity of amnesia. ^[1]
Dissociative fugue could last from days to months and once recovery occurs it is rapid and complete. Some refractory cases have been observed but usually it is just one episode.^[2]
