For youth, sport is the leading cause of concussion. For the rest of us, it is other things and factors. We're seeing an uptick in concussions from seniors falling, but that's a discussion for another day.
In terms of a poorly managed concussion, I may defer to the physician. However, in terms of best practices, it's talking about what will make the best impact on that individual, the information we know about activity levels, the amount of rest that's needed, the amount of screen time or no screen time, and how to return to activity but not particular sporting activities. It's making sure that concussions, once they happen, are managed appropriately, meaning employing the best information we have for the best outcome, so that we have the majority of people who have suffered a concussion recover within a period of two to four weeks, depending on how old they are, versus having the longer-term concussion symptoms.
