Amnestic disorder due to use of sedatives, hypnotics or anxiolytics
Transtorno amnéstico devido ao uso de sedativos, hipnóticos ou ansiolíticos
CategoryDefinition
All definitional requirements for amnestic disorder are met. The memory symptoms are judged to be the direct consequence of use of sedatives, hypnotics or anxiolytics. The intensity and duration of use of sedatives, hypnotics or anxiolytics must be known to be capable of producing memory impairment. The memory impairment may develop during or soon after sedative, hypnotic or anxiolytic 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 use of sedatives, hypnotics or anxiolytics.
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 sedative, hypnotic, or anxiolytic substances or medications.
- This judgment depends on establishing that:
- The amount and duration of use of the relevant sedative, hypnotic, or anxiolytic 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 sedative, hypnotic, or anxiolytic substances or medications.
- The disturbance persists beyond the usual duration of Sedative, Hypnotic, or Anxiolytic Intoxication or Sedative, Hypnotic, or Anxiolytic Withdrawal.
