I have always heard that exercise could and should reduce the risk of aging neurological diseases. Most of these claims were based off of research studies. Which is fine unfortunately most of them were short term studies. The researchers would only take measurements after a few months of time and see that things like blood flow to the brain had increased. They would then logically step in and suggest that increased blood flow will slow the natural deterioration of the brain. These claims are good they lack long term brain health benefits. In this study they had a group of 299 older adults male and female record how much they walked per week. Those who averaged 72 blocks or roughly 7 miles per week were able to maintain a higher amount of gray matter over the course of nine years. There is the difference. Patients had a follow up after 9 years. No that is what I call a good long term study on brain function and health. The other cool thing that the researchers did was they actually took measurements by conducting brain scans on patients before and after thus helping to give concrete facts over just what the patient "feels".
