Same for me and exams, I do really well because of my memory and if they let me sleep in class I'm less disruptive, all depends if the teacher is smart enough to clue into that or not (I still go to college and take training from time to time). I can't focus on stuff I don't give a shit about but hyperfocus on stuff I find interesting. Good for investigating things I probably shouldn't 😝. One of the ways it gets me, when something doesn't add up, it stands out like a sore thumb, it's kind of an uneasy feeling given the world we live in.

I still have my auto-immune that messes with me but being born with it, I don't know any different I guess, I just ignore the pain until it's life threatening and I have to seek treatment, otherwise nothing anyone can do but control my environment and eliminate the triggers as best as possible to avoid reactions. That will catch up at some point, dunno when, push the limits until I can't anymore. It's good that you get to walk around when you get restless, I can't handle a desk job at all, I tried it, it's too much. If I don't burn my energy, I get insomnia really bad.

At the end of the day, nobody really understands except the person going thru it, it's complex to explain something we don't even understand ourselves. I think just them being mindful and supportive of that, he will do great. Hope you get your wish to live closer and spend more time, it's precious.
