Lots of walking may improve memory

October 13, 2010

A new study finds, walking that distance appears to protect against brain shrinkage in old age, which in turn helps stem the onset of memory problems and cognitive decline.

Researchers say the relationship between walking and gray matter volume appears to apply only to people who regularly walk relatively long distances that equal 6 to 9 miles a week.

Scientists reporting in the journal Neurology say the more someone walks the more gray matter tissue the prison will have a decade or more down the road in regions of the brain that are central to cognition
