Many studies have linked exercise with improved brain health later in life. Now a new controlled trial reveals more about how aerobic activity might be helping to bolster the brain by beefing up the hippocampus.
As we age, parts of the brain tend to shrink—even in the absence of neurocognitive diseases, such as dementia or Alzheimer's. The new research shows that at least some parts of the brain can be saved from atrophy—and even built up—by relatively modest amounts of activity late in life. The findings were published online January 31 in Proceedings of the National Academy of Sciences and could have implications for preventing memory decline in the growing segment of older adults in the U.S.
