I recall an American football study looking for concussion symptoms and impairment.
They found people with a history of repeated concussions, and then as what they thought might be a group to compare to some American football linemen with no history of concussions to compare with.
They found linemen with the same issues despite no concussion history.
This raised the possibility that worrying about severe hits that result in a concussion was possibly missing a larger issue.
It seems our understanding of brain injury and even how it comes about may be inaccurate.
