According to a latest study, brisk walking for 30-50 minutes about four times a week may improve cerebral blood flow by 15 percent in elderly women.
The study of three months, lead by Rong Zhang at the Texas Health Presbyterian Hospital's Institute for Exercise and Environmental Medicine in Dallas, comprised of 16 women aged 60 and older.
"There are many studies that suggest that exercise improves brain function in older adults, but we don't know exactly why the brain improves. Our study indicates it might be tied to an improvement in the supply of blood flow to the brain," said Zhang.
