Moderate Exercise May Improve Memory in Older Adults

A new study in older adults shows that brisk walking can increase the size of a brain region involved in memory formation. The finding suggests that moderate physical exercise can help protect the brain as we age.

The brain region called the hippocampus begins to shrink in older adults as part of the normal aging process. This can contribute to forgetfulness, memory loss and increased risk of dementia. Physical fitness is known to be associated with both increased hippocampus size and improved cognitive ability. However, it was unclear how exercise might affect people who’d already had some hippocampus deterioration as a result of aging.
