Actividades cognitivas y funcionamiento cognitivo en personas muy mayores

Abstract

Introduction The aim of this study was to analyse whether the activity is a protective factor of intellectual decline, and specifically to examine whether intellectual activity versus other activities, is a better predictor for the maintenance of cognitive functioning in a group of people over 90 years, independent in basic daily living activities and having preserved cognitive capacity. Material and methods This sample was selected from a bio-psycho-social longitudinal study of independent persons 90 and over. This is a longitudinal study involving 188 people, 67 males and 121 females. Measurements were taken of cognitive functioning and level of activity and repeated between 6 and 14 months; inferential analysis was performed at baseline and follow-up. Results At base-line, there is a strong association between the level of activity and performance. Also, and most important, intellectual activities at baseline predict cognitive functioning at follow-up. According to our results, intellectual activities and the maintenance of cognitive functioning are associated with the absence of cognitive impairment in the very elderly. Conclusions This has important implications for the scientific community in finding a predictive index and strategies, but also for the individual to identify factors of change on which to act to reduce problems associated with aging.
