Preoperative cognitive screening tools

Abstract

• Of the 29 cognitive screening tests that fit inclusion criteria, 7 tests have been used in preoperative settings. • These 7 had an average administration time ranging from one to 10 min. • Memory, language, and attention were the most commonly evaluated cognitive domains. • Most had adequate sensitivity and specificity to detect cognitive impairment/dementia. • The tools discussed are appropriate for lay examiners, are short in duration, and accessible for free or at a low cost.
