I've worked with a few athletes who suffered TBI's, i.e.: football player, downhill skier, water skier, etc. Working with Aphasics and patients with other cognitive disorders is rewarding work (when you see progress). Unfortunately, they were all young and their recovery was minimal.
I wonder how much brain damage I suffered as a kid after playing football without gear, banging my head on school lockers and smashing lunch boxes against my forehead.
