There are several types and levels of severity for asthma though and for example I am unlikely to die if I start having asthma during a dive because I never had asthma so bad that I would gag for air unless I have been already sick with bronchitis and already had some asthma recently.My eyeballs popped out of my head when I read that line about how she didn't have seizures "all the time." But after I stuffed them back in, I reread it and wondered if it might be a mistranslation. Maybe what he said was more like "she took her medication and never had seizures anymore." I'm not fully up on the current dive medicine; I know asthma used to be an absolute contraindication but now it's considered acceptable if it's well-controlled. Is the same true of epilepsy or nah?
I do not know if this compares well with epilepsy … I am not an expert but it seems unlikely to me that one can survive epilepsy in water at depth.
