Dementia due to use of alcohol

Demência decorrente do uso de álcool

Category

Definition

Dementia due to use of alcohol is characterised by the development of persistent cognitive impairments (e.g., memory problems, language impairment, and an inability to perform complex motor tasks) that meet the definitional requirements of Dementia that are judged to be a direct consequence of alcohol use and that persist beyond the usual duration of alcohol intoxication or acute withdrawal. The intensity and duration of alcohol use must have been sufficient to produce the cognitive impairment. The cognitive impairment is not better accounted for by a disorder or disease that is not induced by alcohol such as a dementia due to another disorder or disease classified elsewhere.

Coding Note

This category should never be used in primary tabulation. The codes are provided for use as supplementary or additional codes when it is desired to identify the presence of dementia in diseases classified elsewhere. When dementia is due to multiple aetiologies, code all that apply. This category should not be used to describe cognitive changes due to thiamine deficiency associated with chronic alcohol use.

Diagnostic Criteria

  • All diagnostic requirements for Dementia are met.
  • There is evidence from history, physical examination, or laboratory findings that the Dementia is caused by the direct physiological consequences of use of alcohol.
  • This judgment depends on establishing that:
  • The amount and duration of alcohol use is known to be capable of producing Dementia; and
  • The course of the Dementia (e.g., onset, trajectory of symptoms) is consistent with causation by alcohol.

Exclusions

  • Wernicke-Korsakoff Syndrome
  • Korsakoff syndrome

Inclusions

  • Alcohol-induced dementia
