Ive only had 1 EEG show up. And that was when I had my "first" seizure and it landed me in the hospital of course and so i had no meds in my system at all yet eather. And they did the EEG and i was wide awake and it showed i was having them while awake. I was then dxed with complex partial seizures. However since having sevral more EEGs they have come up negative, but i dont think its going to nessisarly show anything when your on a boat load of meds. The 1 eeg I had it even showed somthing, i cant remember the name and i asked what that ment and she said it meens that your meds are sitting on your brain!
