Impact du style de vie sur le vieillissement cognitif : Étude des modérateurs du déclin cognitif tout au long de la vie adulte. Comment les différences hommes/femmes amènent à reconsidérer l'influence du style de vie sur le fonctionnement cognitif ?

Abstract : Cerebral plasticity provides an opportunity for each individual to maximize his/her cognitive performance through the adoption of enriched behaviors (i.e., Cognitive Enrichment Theory). From this perspective, we had articulated work hypotheses inherent to the moderating role of lifestyle on the age-related cognitive decline throughout adult lifespan, and we observed the role of sex in this relationship. The scientific contribution of this work occurred through the creation and validation of a lifestyle questionnaire (study 2) and two observational studies about (i) physical activity (study 1) and (ii) the general lifestyle (study 3). Results of this thesis showed the existence of different models influencing cognitive aging, as well as an important moderating role of sex in the relationship between lifestyle and age-related cognitive decline. More specifically, results highlighted that general lifestyle, as well as dimensions including social relationships, long-term physical activities and other leisure activities, were effective for cognitive aging in women only. While cognitive solicitations did not show to slow down the cognitive decline, they had a positive influence on cognitive performances in both women and men. This PhD demonstrated that lifestyle can be an effective way to combat the deleterious effects of aging and could not only add years to life, but also add life to years.
