Un caso di Alzheimer su tre è prevenibile modificando lo stile di vita, a cominciare dalla pratica di sport o dalla rinuncia al fumo.
Oltre a sedentarietà e tabacco, le altre principali cause scatenanti sono il diabete, l'ipertensione, l'obesità, ma anche la depressione e lo scarso livello d'istruzione, stando ai risultati della ricerca pubblicati sulla rivista The Lancet Neurology. Per gli esperti dell'Università di Cambridge, riducendo del 10% ciascuno dei fattori di rischio si potrebbero evitare 9 degli oltre 106 milioni di casi di demenza senile previsti per il 2050.
Ciò significa però anche che esistono ragioni della malattia la cui origine resta sconosciuta, concludono gli scienziati.
