Many people think that concussions are mostly caused by sporting injuries.


They are surprised to learn that the majority of brain injuries are from car accidents.

  1. Approximately 50% of TBIs are the result of motor vehicle, bicycle or pedestrian-vehicle accidents.
  2. Falls are the second-commonest cause of TBI (20-30% of all TBI), being more frequent among the elderly and the very young population.
  3. Violence-related incidents account for approximately 20% of TBI.
