精神活性物质（包括治疗药物）所致痴呆

定义

精神活性物质包括药物所致痴呆的形式可判断为物质使用的直接结果，且持续时间明显超过物质中毒或戒断时的认知损害持续时间。物质使用的量和持续时间足以引起认知损害。认知损害不能被非物质所致障碍或疾病解释，例如由分类于他处的疾病所致痴呆。

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.
