Dementia due to use of sedatives, hypnotics or anxiolytics

Demência devida ao uso de sedativos, hipnóticos ou ansiolíticos

Definition

Dementia due to use of sedatives, hypnotics or anxiolytics 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 sedative, hypnotic, or anxiolytic use and that persist beyond the usual duration of action or withdrawal syndrome associated with the substance. The amount and duration of sedative, hypnotic, or anxiolytic use must be sufficient to produce the cognitive impairment. The cognitive impairment is not better accounted for by a disorder that is not induced by sedatives, hypnotics, or anxiolytics such as a dementia due to another medical condition.

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.

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 the 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 Dementia; and
  • The course of the Dementia (e.g., onset, trajectory of symptoms) is consistent with causation by sedative, hypnotic, or anxiolytic substances or medications.

Inclusions

  • Late-onset psychoactive substance-induced psychotic disorder
