Do Blue Zones get dementia? Unpacking the secrets of cognitive longevity

While the United States faces a rising number of Alzheimer's cases, with projections reaching 13 million by 2050, the five Blue Zones around the world show remarkably low rates of dementia. Researcher and author Dan Buettner noted that people in Ikaria, Greece, live approximately eight years longer on average than Americans, and with “no discernible dementia”. This extraordinary disparity suggests that lifestyle and environment play a powerful role in protecting cognitive health, even into old age.
