From what I've seen though (note, I'm no medical expert, just someone with a tv), this is a major issue on the whole anyway. Doctors need to find what the trigger is to know what the cause is. I don't know your medical history, but was you a known epileptic before your first eeg or only a suspected epileptic?

Similar things happen (or used to happen a few years ago) with diabetics. They have to drink a litre of sugar solution and wait a bit to see if the body deals with the sugar like it should. Yet too much sugar in a diabetics blood can be fatal.

Hell, even vacinations could be called backward logic. The injection of sometimes live viruses or bacterium into ones body so that the immune system can build a defense against them. My mum had the flu jab this year and a week later she fell ill with mild flu symptoms.

I guess its just the fact that medics aren't mind readers / all knowing miracle worker and need proof of stuff that isn't that easy to prove otherwise... Also, doctors do make mistakes, but they do usually try to help so don't hold it against them. (unless they're murderous or imbeciles )
