The development of postoperative confusion in older patients is increasingly being recognized as clinically significant because it is becoming more common as the population ages. Postoperative delirium and postoperative cognitive dysfunction differ in time course of development. Risk factors other than age include certain medications as well as anesthesia (both the type and amount used). Postoperative delirium and postoperative cognitive dysfunction appear to increase a patient's risk for developing dementia. Routine preoperative screening may help to identify patients with preexisting cognitive impairment who are at greatest risk for developing postoperative delirium or postoperative cognitive dysfunction.
老年患者术后意识模糊的情况越来越被认为具有临床重要性，因为随着人口老龄化，这种情况越来越普遍。术后谵妄和术后认知功能障碍在发展的时间进程上有所不同。除年龄外的风险因素包括某些药物以及麻醉（所用的类型和剂量）。术后谵妄和术后认知功能障碍似乎会增加患者患痴呆症的风险。常规术前筛查可能有助于识别那些已存在认知障碍、发生术后谵妄或术后认知功能障碍风险最高的患者。
