There was no concussion protocol until after my last concussion. Concussions were know to be problematic but some med professionals discounted the seriousness of concussions. After my bad concussion at 10 due to a bike fall that left me in the hospital for 3 days with slurred speech, the rest of my concussion were things like hitting my head into a overhead beam or heading a soccer ball or a violent shaking from an amusement park ride. I was assaulted and violently slugged in the head twice.
