I'm getting a little nervous about it, everything from not having a seizure to having a really bad seizure. No seizure and it's a worthless hospital stay, a cardiac related seizure may not show brain activity and a bad seizure may cause permanent damage. I need the 5-dy EEG to help me find the cause and gain better control. The reality is anyone could have a seizure not related to brain activity or permanent damage from a seizure without being hospitalized for an EEG. I just have more time to worry about it.
