Repeated blows to the head can cause addiction problems, and depression...
I agree there have been cases of career ending head injuries and concussion related symptoms, not arguing that at all but why has it taken so long for the NHL to "tone it down" when it wasn't until 1979-1980 that players were actually required to wear a helmet?
Enforcers that have passed on didn't do so primarily because of head injuries, the media likes to place blame on that factor. The biggest majority battled drug and alcohol addiction most likely brought on by opiates and/or suicide.
So your biggest factor is caused by blows to the head, which does need to be studied more, but they're finding out a lot quicker than they expected, especially with all the brains they're being donated that have cte.
So its all the same homes.
