The DSM-IV criteria, clinical presentation, etiology, and treatment for an amnestic disorder are described as follows.

Etiology:

  • medical condition for which an amnestic disorder presents itself as a symptom
  • substance-induced
  • unknown

Criterion:

  • difficulty recalling information/events that the patient was once able to recall
  • new information and events are not learned or remembered
  • the condition is severe enough that the patient's ability to function in life is impaired, and is worse than observed prior to the onset of symptoms

Treatment

  • no known effective treatment, any recovery is over time and without intervention
  • if the individual is showing symptoms Korsakoff's syndrome, a thiamine deficiency resulting from alcohol abuse, treatment with thiamine supplements may prevent the condition from developing

Clinical presentation

  • unable to recall memory, new or old
  • time and space disorientation
  • some have no self-awareness of their impairments, or are aware, but do not have an emotional response
  • changes in personality
  • confabulation
