Thousands of Sub-concussive Hits Can Lead to CTE

What I found in football players surprised me because I really hadn’t realized that they were getting repetitive brain trauma. And the reason for that is you don’t see it. It’s an invisible injury. There’s no blood. There’s no pain. They’re not immediately affected because what we’ve learned now is that those low-level hits, the sub-concussive hits, they’re not symptomatic. They don’t cause them to play poorly. You know, they feel fine. They play very well through them, but we’ve found that the cumulative exposure to these low-level hits that happen on every play of every game in football. That is what leads to this neurodegeneration called CTE. That it’s a small level of damage that occurs, but with repetitive injury, which could be small, but just over the thousands and thousands of hits that they get through their career, it provokes a neurodegenerative disease.
