Our concussion clinic was covered by insurance. Vestibular therapy was also covered. Eye therapy was not.

MrT-Man's post is spot on. It's called 'exertion therapy.' Dale Earnhardt Jr's book 'Racing to The Finish' details his steps. I'm about halfway through the book and he does a good job describing the therapy. So far, not much on his diet, but you do want to support your recovery with good supplements and keto diet was tremendously helpful for us.
