Why can't we see CTE's in football players and other until after they die? Even with all our technology? (lemmy.world)

What is a CTE?

[โ€“] Vanth@reddthat.com 1 points 3 weeks ago* (last edited 3 weeks ago)

Chronic traumatic encephalopathy.

It's a summation of low grade damage over years and years from activities like football, rugby, hockey. Physical evidence requires an autopsy or maybe tracking changes in the brain over years (which no NFL player watching out for his paycheck is going to want to do).

That's not to say there won't be a way to detect it in still-live people in the future. CTE is still "new" in the context of medicine, which moves at glacial paces.
