Increasing your activity benefits more than just your muscles—it can be a major brain booster as well.
German researchers recruited 47 people, ages 45 to 89, and used high-resolution magnetic resonance imaging to examine the blood supply to the hippocampus—a small area in the brain that is considered the “control center” for memory. The participants were also evaluated in memory performance, ability to concentrate, and speech comprehension.
Twenty of the participants were found to have alterations in the blood vessels in their brains that affected blood supply to the hippocampus. This group also had lower scores on cognitive tests, leading the researchers to conclude that the supply of both blood and oxygen coming through the blood vessels could have a significant effect on memory function.
“This study shows a clear link between blood supply to the hippocampus and cognitive performance,” study coauthorBicycling“This suggests that brain blood flow might play a key role in the declining of memory performance caused by age or disease.”, could have an influence on the formation of blood vessels that supply the hippocampus, as well as the efficiency of how they deliver blood to that area.
