“…Older age has been found to significantly increase the probability of obtaining lower scores, whereas the worst performance has been found among those with lower education levels, and ceiling effects have been observed among highly educated individuals (Anderson, Sachdev, Brodaty, Trollor, & Andrews, 2007;Bravo & Hébert, 1997;Gallacher et al, 1999;Matallana et al, 2011;Moraes, Pinto, Lopes, Litvoc, & Bottino, 2010). The magnitude of the effect of education level is so strong that the education is invariably considered a criterion for the establishment of normative-data for the MMSE (Han et al, 2008;Mathuranath et al, 2007;Measso et al, 1993). Previous studies regarding gender have proved to be more controversial; only few found a significant association between this variable and cognitive screening tests performance (Mías, Sassi, Masih, Querejeta, & Krawchik, 2007;Ribeiro, Oliveira, Cupertino, Neri, & Yassuda, 2010;Scazufca, Almeida, Vallada, Tasse, & Menezes, 2009).…”
