fears that the coming silver tsunami will trigger a dementia
epidemic, a surprising new study suggests that it may be
possible to delay — or even prevent — some kinds of

addition, the average age when people showed symptoms rose
from 80 to 85, researchers discovered.
findings were published recently in the New England Journal of
report analyzed data from a long-running study of thousands of
people in a small Massachusetts town.
scientists don’t know the exact reason for the decrease in
dementia cases, they highlight two contributing factors:
education level and heart health.

studies have revealed a link between higher levels of
education and better overall health.
largest decrease was reported in dementia cases caused by
stroke and other vascular diseases. People in the study who
improved their heart health saw a reduction in their dementia
