The danger of growing neurodegenerative illness in former skilled soccer gamers varies by place and profession size however not by taking part in period, in response to a landmark examine.
Research from Professor Willie Stewart, who leads the FIELD (Football’s Influence on Lifelong Health and Dementia Risk) examine, beforehand discovered that former footballers are 3.5 instances extra more likely to die with dementia than most of the people.
New analysis has proven that outfield gamers had been 4 instances extra more likely to be identified with neurodegenerative illness with the danger being highest amongst defenders, who’re 5 instances extra more likely to have dementia than non-footballers.
The examine, which in contrast well being information of seven,676 Scottish male gamers, discovered that the danger elevated with the size of their careers, however the findings remained the identical for gamers whatever the period during which they competed.
“With the current data, we’re now at the point to suggest that football should be sold with a health warning saying repeated heading in football may lead to an increased risk of dementia,” Stewart mentioned.
“The information from this paper is the lacking hyperlink in attempting to know this connection between sport and dementia… There isn’t any different proposed danger issue and that is one we may actually tackle and remove this illness.
“I think football has to ask the difficult questions: is heading absolutely necessary to the game of football? Is potential exposure to degenerative brain disease absolutely necessary? Or can some other form of the game be considered?”
Last week, the Football Association (FA), Premier League and different governing our bodies introduced pointers limiting “high-impact” headers to 10 per week in coaching from the 2021-22 season.
Stewart criticised the rules, which had been applied as a precautionary measure, arguing they had been primarily based on “unscientific guesswork”.
“There is no basis on which to say 10 headers of a certain level will somehow produce no risk or even make a great difference to risk. It is a best guesstimate and we would have to wait 30 or 40 years to see the impact,” he mentioned.
The analysis, funded by the FA and the Professional Footballers’ Association (PFA), was performed by the University of Glasgow and printed within the journal JAMA Neurology on Monday.
