So “managing” means he was diagnosed with epilepsy at some point and is taking something for them. It doesn’t mean he’s had a recent seizure, also doesn’t mean he hasn’t. But it means it’s in control.
Seizure medication is fairly straightforward and not that big a deal. Keppra, for example, is safe to give during pregnancy and has the side effect of making people cranky. Hell, aspirin is technically an anti epileptic drug. the worst side effect from commonly prescribed drugs is probably hyponatremia from carbamezapine.
there is a drug called fycompa that has the side effects of delirium and homicidal ideation, which we always laugh about in the office and never prescribe.
there are specific seizure disorders that hit you in childhood like Lennox gastaut or whatever but that is severe and I doubt he could be where he is athletically if he’d been afflicted with it.
teams manage their players meds at big schools, certainly places like UGA or OSU. two schools have checked off on him. I can’t imagine this would impact him at the nfl level.
plus, every nfl player is at risk for seizures since one of the most common cause of them is concussions.
overall I doubt this is a big deal
