致幻剂所致焦虑障碍

定义

致幻剂所致焦虑障碍的特征是在致幻剂中毒期间或中毒后不久出现焦虑症状（如忧虑或担心、恐惧、过度自主神经觉醒的生理症状、回避行为）。这些症状的强度或持续时间大大超过致幻剂中毒特有的焦虑症状。使用致幻剂的数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、抑郁症伴有明显焦虑症状）不能更好地解释这些症状、 如果焦虑症状出现在使用致幻剂之前，如果症状在停止使用致幻剂后持续相当长一段时间，或者如果有其他证据表明之前已经存在伴有焦虑症状的原发性精神障碍（例如，与致幻剂无关的既往发作史），则可能属于这种情况。）

Hallucinogen-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 hallucinogens. The intensity or duration of the symptoms is substantially in excess of anxiety symptoms that are characteristic of hallucinogen intoxication. The amount and duration of hallucinogen 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 hallucinogen use, if the symptoms persist for a substantial period of time after cessation of the hallucinogen use, 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 hallucinogen use).
