According to the AP, the NCAA will be donating $400,000 to help fund a research project;
The National Sport Concussion Outcomes Study Consortium plans to study more than 1,000 male and female college athletes who compete in 11 sports at three schools. Researchers hope to track those athletes after their college careers end and examine the long-term effects of head injuries in hopes of gaining a more comprehensive understanding about brain injuries.
As you can see the actual long-term studies with current technology and assessment tools is JUST NOW getting underway. I don’t believe we will actually fully understand the impact until the longitudinal studies are completed. We should get our first glimpse from research Down Under.
