The character in question is a seven year old girl with some sort of psychic abilities (so far not fully developed and open to change). She experiences seizures, which the people within her culture (the less 'advanced', colonized culture) interpret as visions from one of their gods. Whether that's true or not doesn't matter--I'm trying to figure out how the more scientifically oriented culture would look at these.
What I want is to figure out specifically what kind of seizures she might be having. I did a little research, and as far as what I had in mind for effect, the classic tonic-clonic seizures sounded right (though I'm beginning to suspect that's just because I know nothing about epilepsy and was jumping to the stereotype--bad author!). But I want something that has associated hallucinations that could be interpreted as visions. Everything I've found about hallucinations caused be seizures seems to focus on partial seizures, which, if that's the only feasible thing, would be fine, but I want something dramatic enough that people in the community would really notice it.
I'm poking around the Epilepsy Foundation's website, and I've been doing Google searches on things like "hallucinations seizures" or "hallucinations epilepsy", but a lot of what I'm coming up with has to do with side effects of medications (not useful at the moment), or psychology articles I can't understand.
So, my questions are: What are some possibilities for types of epilepsy that could be interpreted as visions? What sort of things would it be useful for me to research?
I'd also really love to hear any personal experience from people who have had seizures, and just what it's like. Any thoughts about writing about epilepsy would be great.
