“…The CERAD-NAB assesses a wide variety of cognitive functions, is easy to administer after appropriate training (also by non-psychologists), is standardized, and there are normative values for normal controls from the CERAD registry [6,8,19] and from several observational and longitudinal studies [20,21,22], and from 1,100 elderly Swiss individuals allowing calculation of demographically adjusted (age, gender, and education) standard scores [17,23]. Apart from English and German, the CERAD-NAB has been translated into several languages and validated in different cultures [24,25,26,27,28,29,30,31,32]. This potentially allows defining POCD as a change in cognition based on demographically adjusted data.…”
