Those... those pages could have been about anybody who wanted a superficially good-looking resume, if you just replace the word "autism" with literally any other popular cause. And possibly I'm being a bit negative here, but I get a strong vibe of it being more "We're trying to help those poor people", if you see what I mean. Kind of an attempt at kindness to make oneself feel better, without actually paying any attention one way or the other to the people you're trying to help or acknowledging that they have any valuable input (kind of treating them like an object you can throw some activity labeled compassion at in order to get good karma), and not actually trying to identify with them in any way. I'm basing that on self-descriptors like "charismatic" and incredibly generic and vague "goals" when discussing the organization, there.
I suppose that's kind of your point, isn't it?

You might want to get it checked out, especially if there's tenderness there or you start to feel disoriented again. I once fell directly on my head on a concrete surface and was fine (man, that was an... interesting prom, and just to make it even more enigmatic there was no alcohol involved, just stupidity), so there's definitely precedent for doing okay after a head injury, but it's far better to be safe than sorry if you can spare the time and/or cash for an ER visit or whatever you think is appropriate. Couldn't hurt to give a First Nurse line in your area a call, if there is one.
Also, he probably got promoted from a job he was actually decent at into one he's not even slightly competent at.
