If this Valero situation was caused by CTE, does boxing need to do more?(long, sorry)

[Nameless]

Not sure...I mean I know he had problems from his accident and the head plate and all but don't know if or how much worse boxing had made it...Are they doing an autopsy?

You just need a good head trauma to see your personality seriously bust your personality, the accident could solely be the cause of it and perhaps boxing did made it worst but just with that accident it could scientifically be explainable.

Pardon me... it was an elbow, not a headbutt.

How significant was this injury, considering he fought on?

It is difficult to say because many consequences are shown up quite late after the injury, it really depends. Personally, I don't think that this injury did trigger the whole, I think more that it's the accident he had in 2002 and where they had to put a metal plate in his head or something like that that could have been the major cause of his behaviors, the shot to the heads sustained subsequently not helping the cause, obviously.
