Concussion denial: in mixed marital art (or UFC) fighting like bike helmet debate?

All of this vindicates my decision to never let my sons participate in football.

Frontline aired a really good documentary based on a book of the same title called League of Denial about the dangers of repeated traumatic brain injury in football (though it could certainly apply to any sport where there may be repeated head injuries). You should certainly feel vindicated - I believe I recall that when the scientists were able to study the brains of teens who played football and died from other causes, that they found early but visible and noticeable changes to those brains from TBIs.

The hospital that I work at has been developing a helmet with accelerometers and other sensors that is supposed to help decide how to pull players out of games before they actually reach injury stage, and standards on how long to keep them out, but I can't help but think that the damage is more subtle than we really know and even using this technology will be too little, too late.
