咖啡因所致焦虑障碍

定义

咖啡因诱发焦虑症的特征是在咖啡因中毒或戒断咖啡因期间或之后不久出现焦虑症状（如忧虑或担心、恐惧、过度自主神经唤起的生理症状、回避行为）。症状强度或持续时间大大超过咖啡因中毒或咖啡因戒断所特有的焦虑症状。咖啡因的使用量和持续时间必须能够产生焦虑症状。原发性精神障碍（如焦虑和恐惧相关障碍、伴有突出焦虑症状的抑郁障碍）不能更好地解释这些症状，如果焦虑症状发生在使用咖啡因之前，如果症状在停止使用或戒断咖啡因后持续相当长一段时间，或者如果有其他证据表明先前就存在伴有焦虑症状的原发性精神障碍（如与使用咖啡因无关的先前发作史），则可能属于这种情况。

Caffeine-induced anxiety disorder is characterised by anxiety symptoms (e.g., apprehension or worry, fear, physiological symptoms of excessive autonomic arousal, avoidance behaviour) that develop during or soon after intoxication with or withdrawal from caffeine. The intensity or duration of the symptoms is substantially in excess of anxiety symptoms that are characteristic of Caffeine intoxication or Caffeine withdrawal. The amount and duration of caffeine use must be capable of producing anxiety symptoms. The symptoms are not better explained by a primary mental disorder (e.g., an Anxiety and fear-related disorder, a Depressive disorder with prominent anxiety symptoms), as might be the case if the anxiety symptoms preceded the onset of the caffeine use, if the symptoms persist for a substantial period of time after cessation of the caffeine use or withdrawal, or if there is other evidence of a pre-existing primary mental disorder with anxiety symptoms (e.g., a history of prior episodes not associated with caffeine use).
