Something as simple as a daily walk may ward off Alzheimer's disease, according to researchers at the University of Pittsburgh.

They found that walking six miles a week significantly reduces a healthy adult's risk of developing Alzheimer's over a period of 13 years.

For people who already had mild cognitive impairment, walking five miles a week reduced brain degeneration and memory loss by more than half.

The findings were presented at the annual meeting of the Radiological Society of North America on Monday.
