Aging Ment Health. 2019 Jul 08;:1-8 Authors: Farina M, Breno Costa D, Webber de Oliveira JA, Polidoro Lima M, Machado WL, Moret-Tatay C, Fernandes Lopes RM, Argimon IIL, Irigaray TQ Abstract Several biopsychosocial changes in individuals' life might happen, resulting in a decline of long-term cognitive abilities.

For this purpose, a longitudinal study was developed including 108 older Brazilians in phase I and 64 in phase II, from 2013 to 2017.
