Exercise may protect against Alzheimer’s

Washington, Feb. 9: A new study now finds that exercise produces a hormone that may improve memory and protect against Alzheimer’s disease.

The study was co- led by Ottavio Arancio, a researcher at Columbia University’s Vagelos College of Physicians and Surgeons and Taub Institute for Research on Alzheimer’s Disease and the Aging Brain.

The study was published in Nature Medicine.

While physical activity is known to improve memory, and studies suggest it may also reduce the risk of Alzheimer’s disease, researchers don’t understand why.

An earlier study discovered a hormone called irisin that is released into the circulation during physical activity. Studies suggested that irisin mainly played a role in energy metabolism. — ANI
