You can always explain anything that needs explanation. I am SURE that your child wouldn't be the first to be misunderstood or to be on the AS spectrum. I definitely don't think any of that would affect elegibility.
But I'd probably wait to hear from the staff before I did anything if I were you. You want to be sure you're following the rules of the application. I'm reluctant to advise you about what they'd need or not need.
If it helps, they really are trying to get a true picture of your child. Don't worry that they're going to be looking for a reason to exclude him. That's NOT what they're about. I promise!
