The health of your arteries could determine how well your memory functions in old age.
In a 14-year study researchers followed nearly 2,000 older Americans who did not have a history of stroke or dementia. They found those whose arteries stiffened the most performed the worst on exams testing memory and learning.
While artery stiffening is a normal part of aging, researchers say it can be lessened through diet and exercise.
The study participants underwent repeated screenings for artery stiffness and brain functions. A subset of 582 people had the most recent test of artery stiffness completed.
