As somebody with epilepsy, hopefully his was only cause by lack of sleep or dehydration, it is possible to develop epilepsy at any stage in life, as I did once I turned 20. It's called generalized epilepsy and has certain triggers (mine is lack of sleep) and as long as i get my sleep and keep up on my medication(took awhile to get that right) I live a 100% normal life with no differences to an average person. Praying for Robert though and hope it's just a dehydration situation
