La sant\u00e9 cognitive des personnes \u00e2g\u00e9es n’est pas une fatalit\u00e9, mais peut \u00eatre influenc\u00e9e dans une large mesure par des facteurs modifiables. La Commission Lancet<\/em> 2024 conclut qu’une part importante des cas de d\u00e9mence peut \u00eatre potentiellement \u00e9vit\u00e9e ou retard\u00e9e au cours de la vie ; la proportion est estim\u00e9e \u00e0 environ 45%. L’augmentation du taux de cholest\u00e9rol LDL et les troubles de la vision non trait\u00e9s sont d\u00e9sormais consid\u00e9r\u00e9s comme des facteurs de risque importants. Parall\u00e8lement, il appara\u00eet que des programmes de pr\u00e9vention multidimensionnels structur\u00e9s peuvent influencer favorablement les trajectoires cognitives dans des \u00e9tudes randomis\u00e9es, en particulier chez les personnes \u00e0 risque \u00e9lev\u00e9 (par exemple, U.S. POINTER, JAMA <\/em>2025). Pour les stades pr\u00e9coces de la maladie d’Alzheimer, il existe en outre des anticorps anti-amylo\u00efdes modifiant la maladie, dont l’utilisation est toutefois soumise \u00e0 des conditions claires en mati\u00e8re de diagnostic et de s\u00e9curit\u00e9 (p. ex. lecanemab, NEJM<\/em> 2023 ; \u00e9tiquetage de la FDA sur les risques ARIA). <\/strong><\/p>\n\n
