Amnestic disorder due to other specified psychoactive substance including medications
Transtorno amnéstico devido ao uso de outra substância psicoativa especificada, incluindo medicamentos
CategoryDefinition
All definitional requirements for amnestic disorder are met. The memory symptoms are judged to be the direct consequence of use of a specified psychoactive substance other than alcohol; sedatives, hypnotics or anxiolytics; or volatile inhalants. The intensity and duration of use of the specified psychoactive substance must be known to be capable of producing memory impairment. The memory impairment may develop during or soon after specified psychoactive substance intoxication or withdrawal, but its intensity and duration are substantially in excess of those normally associated with these conditions. The symptoms are not better accounted for by another disorder or medical condition, as might be the case if the amnestic symptoms preceded the onset of the specified psychoactive substance.
Diagnostic Criteria
- All diagnostic requirements for Amnestic Disorder are met.
- There is evidence from history, physical examination, or laboratory findings that the disturbance is caused by the direct physiological consequences of use of one or more psychoactive substances or medications other than alcohol; sedatives, hypnotics of anxiolytics; or volatile inhalants.
- This judgment depends on establishing that:
- The amount and duration of use of the relevant psychoactive substance(s) or medication(s) is known to be capable of producing the memory disturbance; and
- The course of the memory disturbance (e.g., onset, trajectory of symptoms, response to treatment) is consistent with causation by the relevant psychoactive substance(s) or medication(s).
- The disturbance persists beyond the usual duration of Substance Intoxication or Substance Withdrawal for the relevant psychoactive substance(s) or medication(s).
