A good friend of mine was friends with Dan Brown when they were both kids. Dan broke his back (or something else just as serious), and was in a cast for a year+. My friend used to say that he was normal when he got hurt, but turned into a real menace after the accident.

My friend passed away a couple of years ago, or I'd have him fill in the details.

I wonder if he got a small brain injury. We could add him to a long list of people who have personality changes afterwards.

Eminem had a TBI as a child and I wonder if it turned him into a rapper savant.
