Table : TABLE 8.2 • Dissociative Amnesia Facts at a Glance
Prevalence
  • Dissociative amnesia is rare, and its lifetime prevalence is unknown.
  • Comorbidity
  • Depression, anxiety, and substance-related disorders may be present along with dissociative amnesia. (Note: If the amnesia is a result of substance use, dissociative amnesia will not be the diagnosis.)
  • Onset
  • Children or adults can develop this disorder.
  • Course
  • Patients may have one or multiple episodes of amnesia.
  • In some cases, the episode of amnesia resolves quickly; in other cases it persists.
  • Gender Differences
  • No gender differences in the prevalence of dissociative amnesia have been reported.
  • Cultural Differences
  • Dissociative amnesia may be a culture-related diagnosis; there are no reported cases of this disorder (due to a traumatic event by itself, in the absence of brain damage resulting from the trauma) prior to 1800 (Pope et al., 2007).
