More leisure-time physical activity — walking, gardening, swimming, or dancing, for example — was associated with larger brain volume in older adults, a cross-sectional study showed.
Adults with an average age of 75 who had the most physical activity had a total brain volume that was 1.4% larger than those with the least activity, reported Yian Gu, PhD, of Columbia University in New York City, and co-authors, in an early-release abstract from the American Academy of Neurology annual meeting, which will be held here in April.
