Dementia due to psychoactive substances including medications

Definition

Dementia due to psychoactive substances including medications includes forms of dementia that are judged to be a direct consequence of substance use and that persist beyond the usual duration of action or withdrawal syndrome associated with the substance. The amount and duration of substance 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 substances such as a dementia due to another medical condition.
