Professional rugby union players can experience a reduction in blood flow to the brain and cognitive function over the course of just one season, shocking new research has revealed.
Athletes with a history of concussion may show more serious brain injury from a later concussion, new research has revealed. In comparison to athletes with no history of concussion, those who have sustained head injuries previously may show greater impact, particularly in middle regions of the brain that are more susceptible to damage. Athletes with a history of concussion should be monitored more closely, the research team said in light of their findings. "We know concussions may have long-term effects on the brain that last beyond getting a doctor's clearance to return to play," said study author Dr Tom A. Schweizer, of St. Michael's Hospital in Toronto, Canada.
