When patients present to the emergency department with changes in behavior and levels of consciousness, psychiatric causes often move to the top of the list of diagnostic considerations. It is important to thoroughly assess such patients for medical causes. Although it is not common for primary psychiatric conditions to present with altered levels of consciousness, severe cases may present in this fashion. Altered mental states may also be caused by adverse reactions to psychiatric medications. In this article, the authors review some of the psychiatric causes of decreased levels of consciousness, as well as certain adverse drug reactions to psychotropic medications.
当患者因行为和意识水平改变而前往急诊科就诊时，精神科病因往往会排在诊断考虑因素的首位。对这类患者进行全面的医学病因评估非常重要。虽然原发性精神疾病出现意识水平改变并不常见，但严重病例可能会以这种方式表现出来。精神状态改变也可能由精神科药物的不良反应引起。在本文中，作者回顾了一些导致意识水平下降的精神科病因以及某些精神药物的不良反应。
