I think the best way to address that would be to actually try to prevent those injuries before they happen.
We have a program that is very deliberately and provocatively titled “Stop Hitting Kids in the Head”. We know that children's brains are developing up until the age of 12, 13, 14, and having those children heading soccer balls, getting tackled in football and rugby, and getting body-checked in hockey is a terrible idea. That's the first thing we can do.
The second thing is creating awareness programs. We talked about mandatory education, whether it's parents, teachers or classmates themselves. I think of the story of Rowan Stringer, who suffered a bad concussion, didn't tell her parents, didn't tell her teachers, but had told her friends. Asking somebody who's neurologically impaired to self-report is, again, a terrible strategy. We really have to teach this bystander model of teaching others what to look for and what to recognize.
The first thing that should happen when somebody has a big fall, whether that be on the sports field, in the playground or just a garden variety accident, is thinking about the possibility of brain injury and looking for that behaviour change.
