TL;DR - internet speculation that I’m hopefully wrong about because he won’t have to be on Keppra. More long ranty stuff: The emotional toll of going from top athlete to potential walking seizure can be high, and I say that as a middling-at-best athlete who just rides bikes for fun. Keppra also lists depression as a side effect, so that coupled with a big life adjustment (no driving for six months after a single seizure, no climbing on ladders, walking up the stairs can be dangerous, etc etc etc) is a recipe for potential disaster, and probably why the neurologists implore you to contact them if you feel depressed. It really just depends on what his chances for full recovery are and how he reacts to any subsequent permanent life changes. My seizures were much more mild than his, and I’m not in his shoes as far as future employment opportunities, but I would never put a helmet on again after mine, given the choice. The look on my wife’s face when I wake up from one is not worth all the money in the world, and I’m sure he feels the same about his family.
