The prevention of dementia involves reducing the number of risk factors for the development of dementia, and is a global health priority needing a global response. [1] [2] Initiatives include the establishment of the International Research Network on Dementia Prevention (IRNDP) [3] which aims to link researchers in this field globally, and the establishment of the Global Dementia Observatory ...
The initial 12 risk factors were linked with 40% of cases, but the new report suggests addressing the 14 risk factors could help eliminate or delay 45% of dementia cases, said Livingston, a ...
