Footballers at higher risk of dementia, suggests study in the Lancet Public Health

PARIS: Top level Swedish football players — except for goalkeepers — were significantly more likely to develop dementia than the general public over the last century, a large study suggested on Friday. Experts said the study adds to “convincing evidence” linking the world’s most popular sport to a higher risk of degenerative brain disorders, and comes as head injury controversies rumble throughout other codes such as rugby and the NFL.

While traumatic brain injuries like concussions may be less common in football than those sports, the repeated heading of the ball by footballers has previously been associated with dementia. The new study, published in The Lancet Public Health journal, analyzed the medical records of more than 6,000 male footballers in Sweden’s top division from 1924 to 2019.

The researchers compared their rates of a range of degenerative brain disorders to 56,000 similarly aged Swedish men. The footballers were 1.5 times more likely to get Alzheimer’s disease and other dementias than the control group, the study suggested.

An exception was goalkeepers, who rarely need to head the ball and did not show any increased likelihood of degenerative brain disorders. “This finding lends support to the hypothesis that heading the ball might explain this association,” the study’s lead author Peter Ueda of Sweden’s Karolinska Institutet told AFP.

Ueda said it was the largest research conducted on the subject since a 2019 Scottish study which suggested that footballers were 3.5 times more likely than to get degenerative brain disorders. - ‘Protect people’s heads’ - The Swedish study also found that footballers lived slightly longer than similarly aged men, which Ueda said could be related to the higher levels of
