Exercise May Slow Alzheimer's

Alzheimer's patients may be able to slow the progression of the disease with exercise, a new study has discovered. Patients who were in poorer physical condition experienced up to four times more brain shrinkage than those who were physically fit, WebMD reports.

"People with early Alzheimer's disease may be able to preserve their brain function for a longer period of time by exercising regularly and potentially reducing the amount of brain volume lost," said a researcher. "Preserving more brain volume may translate into better cognitive performance." (More Alzheimer's disease stories.)
