Postoperative cognitive dysfunction (POCD) is a frequent complication to surgery. Studies show considerable disagreement concerning the definition of POCD and the methods used for its -assessment. Objectivity may be obtained through neuro-psychological testing, contrary to the use of questionnaires, but several methodological issues can potentially affect the results. Aspects like baseline performance, practice effects and time interval between test sessions all influence the assessment of cognitive function.
术后认知功能障碍(POCD)是手术常见的并发症。研究表明,关于POCD的定义及其评估方法存在很大分歧。与使用问卷调查相反,通过神经心理学测试可以获得客观性,但几个方法学问题可能会影响结果。诸如基线表现、练习效应和测试时段之间的时间间隔等方面都会影响认知功能的评估。
