Moderate Exercise Among Older Adults Improves Areas Of Brain Associated With Alzheimer’s

July 30, 2013: 12:00 AM EST
A study involving two groups of physically inactive older adults – one of which was diagnosed with mild cognitive impairment (MCI) and at risk for Alzheimer’s disease – who underwent a moderate exercise regimen found improvements in overall cardiovascular fitness in both groups as well as memory recall and brain function. Using neuroimaging, researchers showed that the brain regions with improved efficiency corresponded to those involved in the pathology of Alzheimer's disease. "People with MCI are on a very sharp decline in their memory function, so being able to improve their recall is a very big step in the right direction," the researchers said.
