Elderly people who exercised more often exhibited signs for healthier nerve transmission, which may protect the brain from cognitive decline.
A recent research effort led by Kaitlin Casaletto (University of California; CA, USA) at the head of an international collaboration of North American and European Universities has discovered that higher amounts of physical activity in elderly people is associated with increased presynaptic protein levels in brain tissue. The same correlation was observed in people whose brains exhibited indicators of neurodegenerative disease, suggesting that physical activity may help to suppress age-related cognitive decline.
