I think it's a bit odd that they are saying both seizures were "ideopathic" - no known cause. I don't think most people have grand mal seizures for no reason.

Sounds just like a seizure my brother had on a hot summer day -- some 40 years ago -- never another one; no known cause. You do have to wonder if heat and/or dehydration is a factor.

Dehydration can certainly affect brain chemistry.
