Heard this on my way to work this morning and was reminded of our discussions of CTE from the past. Thought it might be of interest in these parts. Still very preliminary research with small n-size, so nothing earth shaking yet. However, I wonder IF the APOE link is proven in larger trials if this could lead to some sort of screening test, if such a test would actually deter people from participating in concussion-prone activities, and eventually reduce CTE and premature deaths in future generations of athletes by causing people to stop playing football or hitting things with their heads at a younger age.
