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.
