I don't really get what he is being asked to do in this 'vestibular theapy'. From what I can see in the video it looks like stuff that would make my brain melt (running around, catching a ball etc). Presumably this is only for when you've reached a certain level of recovery?

And he is mad for wanting to play again. After such bad pcs from two such seemingly innocuous concussions he's obviously very susceptible - and is being seriously misled by the professionals.

An article on Brian Roberts's recovery (which took 13 months) and return to professional baseball:

"The key was not having a timetable, but focusing on steadily integrating Roberts back into the game – and life – without having a setback. ... 'The condition he has really affected his ability to deal with a lot of activity,' [Dr. Michael] Collins said. 'Certain environments would be quite provocative for him and cause him a lot of stress, and quite frankly could have set him days and even weeks at the beginning of this if he did the wrong activity. What we did was very careful systematic rehabilitation where we slowly integrated him back into these types of environments.'"
