Abstract

Introduction: Functionality refers to the ability of individuals to perform their basic and instrumental activities of daily living safely and independently. Executive functions correspond to cognitive processes that allow behavioral orientation, adaptive response and achieve proposed goals. Memory is an ability to acquire, store and retrieve learned information. The decline of both cognitive functions may impair functionality. In this sense, the present study aimed to study a relationship between executive functions and memory with functional performance in healthy elderly, as well, study the applicability of UPSA (University of California, San Diego, Performance-Based Skills Assessment) in the assessment of functional performance. Methodology: In a convenience sample were included 50 participants with age comprehended between 61 and 92 years old. Executive functions and memory were assessed with neuropsychological measures, functionality was assessed with an indirect measure (self-report) and a with a direct measurement based on participant performance (UPSA). Results: The results support the study hypothesis, since there is a relationship between executive functions and functional performance, however, only Digit Span and Phonological Verbal Fluency proved to be significant predictors of functional performance, contrary to previous studies. Memory only correlated with financial management. Participant performance at UPSA varied with age and residence conditions, and UPSA appears to have superior utility to self-reporting scales in assessing functionality. Conclusions: Working memory and verbal initiative proved to be significant predictors of functional performance, thus demonstrating that subject´s ability to monitor and encode information, as well as maintaining this information in working memory, is essential for everyday function in healthy older adults.
