VISUOSPATIAL IMPAIRMENT AND MORTALITY

Abstract

Comments on an article by Caterina Rosano et al. (see record 2008-12690-004). Rosano et al. recently demonstrated significant associations between gait and the Digit Symbol Substitution Test (DSST) on the one hand and functional outcomes and mortality risk on the other. Both predictors have previously been associated with Executive Control Function (ECF). They conclude that frontal function may be associated with both functional outcomes and survival in older persons. We agree that ECF is an important determinant of functional outcomes, but its specific association with survival is less certain. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
