The article abstract:In the longest-term look ever at concussions in sports, University of Montreal researchers showed that athletes who had suffered even one minor bell ringing on the ice or football field had measurable brain and body reflex impairments 30 years later.
"You don't need to be knocked out or lose consciousness. A ding is enough to make these brain changes," said senior study author Maryse Lassonde, a University of Montreal neuropsychologist.
"If you see stars, that's enough ... and we can see the effects many years later," said Lassonde, who has been neuropsychologist for the Montreal Canadiens for 11 years.
The research was published online yesterday by the journal Brain.
