Amnestic disorder due to psychoactive substances including medications
Transtorno amnéstico devido a substâncias psicoativas, incluindo medicamentos
CategoryDefinition
All definitional requirements for amnestic disorder are met. The memory symptoms are judged to be the direct consequence of psychoactive substance use. The intensity and duration of substance use must be known to be capable of producing memory impairment. The memory impairment may develop during or soon after 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 substance use.
Diagnostic Criteria
Essential (Required) Features:
- 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 a substance or medication that persists beyond the usual duration of Substance Intoxication or Substance Withdrawal. This judgment depends on establishing that:
- The substance or medication and the amount and duration of its use 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 substance or medication.
Note: If the specific substance inducing the Amnestic Disorder has been identified, it should be classified using the appropriate subcategory:
- 6D72.10 Amnestic Disorder Due to Use of Alcohol
- 6D72.11 Amnestic Disorder Due to Use of Sedatives, Hypnotics, or Anxiolytics
- 6D72.13 Amnestic Disorder Due to Use of Volatile Inhalants
- 6D72.12 Amnestic Disorder Due to Other Specific Psychoactive Substance Including Medications
A diagnosis corresponding to the pattern of use of the relevant psychoactive substance (i.e., Episode of Harmful Psychoactive Substance Use, Harmful Pattern of Psychoactive Substance Use, Substance Dependence) may also be assigned.
