Computer use and moderate exercise seem to be good signs for brain health. At the Mayo Clinic, researcher Yonas Geda examined data on 926 people ages 70 through 90. He was looking for signs of mild cognitive impairment, or MCI – a reduction in thinking ability that may be a warning of Alzheimer’s disease.

The study presented at a meeting of the American Academy of Neurology was supported by the National Institutes of Health.
