Wow, growing up I did every activity you could imagine with little or no protection. But so did everyone I knew. We all got banged up pretty good numerous times, but amazingly nothing too serious.
Unfortunately, we don't hear much about it at all in the media since mild brain injuries are still a little understood area of medicine. And there is also probably a lot of psychological trauma out there, too, which makes it difficult for people to figure out why someone came home from the sandbox as a different person, can't hold a job, was always loving but just argues with me now, etc. Did this person have psychological problems, or is it actually the consequence of a brain injury? Add the effects of alcohol and substance abuse on top of that and the true underlying reasons for these problems is hard to see.
Great point. I think this goes hand in hand with our societal stigma and lack of resources in general when dealing with mental illness. I've come to understand why many homeless people have mental issues, even those with active, caring families. Most likely they slipped through the cracks. You'd be amazed how few resources there are available when trying to seek targeted, effective help for a loved one.
