Rx
for the Mind: Mind Games

If you don't use your mind regularly through activities such as
reading, doing puzzles or playing a musical instrument, you risk
losing some of your cognitive abilities as you age.
That's the message from a new study
appearing in the June 19 issue of the New England Journal of
Medicine.
Researchers from Albert Einstein
College of Medicine in New York City found seniors who participated
in mind-stimulating leisure activities had a lower risk of developing
the brain disease dementia.
"Subjects whose levels were
in the top third of the cognitive activity level had almost a
65 percent reduced risk of dementia," says study author Dr.
Joe Verghese, an assistant professor of neurology at Albert Einstein
College.
The researchers measured cognitive
activity levels by asking 469 people over the age of 75 what leisure
activities they participated in, and how often. All of the study
participants lived in the Bronx, one of New York City's five boroughs.
Participating in a cognitive-stimulating
activity one day a week translated into one point on the cognitive
activity level scale.
The researchers asked about a variety
of activities, including playing board games or cards, reading,
writing for pleasure, playing a musical instrument, doing crossword
puzzles, participating in group discussion, dancing, doing housework,
walking, swimming, biking, babysitting and participating in group
exercise.
The cognitive activities that showed
the greatest risk reduction were reading, board games or cards,
and playing a musical instrument. Writing and participating in
group discussions didn't reduce the risk of dementia. Physical
activities, with the exception of dancing, didn't appear to greatly
reduce the risk of dementia.
Every year, for an average of five
years, the study participants were evaluated. During the study
period, 121 study volunteers developed dementia.
By comparing those who developed
dementia with those who didn't, the researchers found that for
one point on the cognitive activity level scale, there was a 7
percent reduction in the risk of dementia. People in the highest
third had a score of 11 points or higher. That means they participated
in mind-stimulating activities more than once a day each week.
Their risk of developing dementia was 63 percent lower than people
who scored in the lowest third of the cognitive activity level
scale.
Verghese says the researchers weren't
able to include past history of these activities in this study.
One reason people might have scored
low on the cognitive activity level scale, according to Verghese,
is that they could have the beginnings of dementia, but not show
outward signs of the disease. To control for this possibility,
Verghese and his colleagues re-examined the data, excluding anyone
who developed dementia in the first seven years of the study,
and the results still held true.
Dr. Joseph Coyle, who wrote an
accompanying editorial, says this study provides a remarkable
contrast to more complex dementia research that focuses on the
specific changes that occur in the brain as dementia develops.
He says after looking at that complexities in some of that research,
it's hard to believe that something as simple as playing cards
could ward off dementia.
Nevertheless, he says, the results
of this study are convincing. "Effortful mental activities
may forestall the onset of dementia," says Coyle, a professor
of psychiatry and neuroscience at Harvard Medical School.
Exactly how it occurs isn't yet
known, he says. But "participating in these activities that
use the brain may stimulate neurons to work around the damage
associated with the early stages of dementia," he says.
So for now, both experts say it's
a good idea to engage in activities that stimulate your mind throughout
your life.
