Exercise Plus Computer Time May Boost Seniors’ Brains

TUESDAY, May 1 (HealthDay News) — A combination of moderate
exercise and mental stimulation through computer use may help reduce the
risk of age-related memory loss more than computer use or exercise alone,
according to new research.

The study, published in the May issue of Mayo Clinic
Proceedings
, included more than 920 people in Olmsted County, Minn.,
aged 70 to 93, who completed questionnaires about their computer use and
physical activity over the previous year.

The Mayo Clinic researchers found signs of mild cognitive impairment in
nearly 38 percent of participants who did not exercise and did not use a
computer, compared with just over 18 percent of those who did moderate
exercise and also used a computer. Mild cognitive impairment is the stage
between normal age-related memory loss and early Alzheimer’s disease.

The investigators also found that 36 percent of participants who did
moderate exercise and used a computer had normal memory function, compared
with about 20 percent of those who did not exercise or use a computer.

Moderate exercise included brisk walking, hiking, aerobics, strength
training, golfing without a golf cart, swimming, doubles tennis, yoga,
martial arts, weightlifting and using exercise machines, the authors
explained in a Mayo Clinic news release.

“The aging of baby boomers is projected to lead to dramatic increases
in the prevalence of dementia,” study author Dr. Yonas Geda, a physician
scientist at the Mayo Clinic in Arizona, said in the news release. “As
frequent computer use has become increasingly common among all age groups,
it is important to examine how it relates to aging and dementia. Our study
further adds to this discussion.”

Although the study uncovered an association between combined exercise
and computer use and better memory function, it did not prove a
cause-and-effect relationship.
