Contact in sports may lead to differences in the brains of young, healthy athletes
Researchers at St. Michael’s Hospital performed preseason brain scans of 65 varsity athletes — 23 from collision sports (with routine, purposeful body-to-body contact), 22 from contact sports (where contact is allowed, but is not an integral part of the game) and 20 from non-contact sports. They found that the athletes in collision and contact sports had differences in brain structure, function and chemical markers typically associated with brain injury, compared to athletes in non-contact sports. Their findings were published online today in the journal Frontiers of Neurology.
