Demência due to uso 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 Demência that are judged to be a direct consequence of sedative, hypnotic, or anxiolytic uso and that persist beyond the usual duration of action or abstinência syndrome associated com the substance. The amount and duration of sedative, hypnotic, or anxiolytic uso must be sufficient to produce the cognitive impairment. The cognitive impairment is not better accounted for by a transtorno that is not induced by sedatives, hypnotics, or anxiolytics such as a Demência due to another medical condition.
