6D84.1 Dementia due to use of sedatives, hypnotics or anxiolytics

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2025-01

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.
