Using a computer may protect against memory loss late in life, as long as you also make sure to exercise, a new study suggests. In the study, which included older adults, computer use and exercise reduced the risk of memory loss, whereas doing either activity alone did not.

Participants who engaged in moderate physical activity (such as brisk walking) and used a computer were 64 percent less likely to have mild cognitive impairment compared with those who did not exercise and did not use a computer. However, the study relied on participants to remember how often they had exercised or used a computer in the past year. More studies will be needed that follow people forward in time to confirm the results.

Mild cognitive impairment is a condition in which people experience noticeable declines in their cognitive function, including memory and language problems, but are still able to perform everyday activities.

Computers and exercise
Some previous studies have found a link between exercise and a reduced risk of mild cognitive impairment (MCI), while others have linked cognitively stimulating activities, such as reading books, playing games or using a computer, and a reduced risk of mild cognitive impairment. But no studies have examined the combined effects of exercise and computer use.

A study of 926 people ages 70 to 93 living in Olmsted County, Minn. was conducted. Participants were asked whether they had engaged in moderate physical activity, such as brisk walking, hiking, aerobics, strength training, yoga or weight lifting, in the past year, and how frequently they participated in the activities. They were also asked about the extent of their computer use. Participants were examined by a physician to diagnose mild cognitive impairment.

Of the 205 study participants who did not exercise and did not use a computer, 41 (20 percent) showed signs of MCI. Of the 314 who both exercised and used a computer, 20 (6 percent) showed signs of MCI, the study found.

People who either used a computer or exercised experienced some protection against mild cognitive impairment, compared with people who did neither activity, but that finding could have been due to chance, the study said.

The results held even after the researchers took into account factors that could affect cognitive function, such as age, sex, education level, depression and the number of calories they ate in a day.

Protecting the brain
The researchers speculated that people who engage in both physical activity and computer use may be healthier, more disciplined individuals. In other words, these activities could simply be a marker for a healthy lifestyle.
