Dementia due to use of volatile inhalants
Demência devida ao uso de inalantes voláteis
CategoryDefinition
Dementia due to use of volatile inhalants 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 inhalant use or exposure and that persist beyond the usual duration of action or withdrawal syndrome associated with the substance. The amount and duration of inhalant use or exposure must be sufficient to be capable of producing the cognitive impairment. The cognitive impairment is not better accounted for by a disorder that is not induced by volatile inhalants such as a dementia due to another medical condition.
Coding Note
Diagnostic Criteria
- All diagnostic requirements for Dementia are met.
- There is evidence from history, physical examination, or laboratory findings that Dementia is caused by the direct physiological consequences of the use of volatile inhalants.
- This judgment depends on establishing that:
- The amount and duration of volatile inhalant 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 volatile inhalants.
