The most important thing that she needs to do is figure out whether or not these are actually neurological seizures so that she gets the appropriate workup and treatment. Whenever there's a question of what a spell may be, we like to admit the patient to an epilepsy monitoring unit, where they're hooked up to a continuous EEG monitor as well as 24hr videotape. We then attempt to "capture" an event in the next few days so that we can look at the EEG and video to see if it's a real seizure. If she has a spell and the EEG is completely normal, then it's unlikely that these are really seizures. They may represent stress, psychological problems, or even cardiac problems (although usually there's an EKG attached too). Psychiatry, antianxiety/psyche meds or counseling may need to be initiated. IF on the other hand, there is a change on the EEG then she's probably having seizures and will need treatment. Just because you stay awake and answer questions does not mean this isn't a seizure. Have her discuss this with her parents and primary care physician to see what direction they want to pursue. Good luck.

I hope this is of help to you.
Hope you find your answers. You can look up the epilepsy foundation at www.efa.org to see if a center is located near you.
I have had numerous tests done, all of which I have found to be somewhat helpful. As for the overnight stay in the hospital, after being admitted, the doctors will take you off of all medications that you may be on. They hook you up to an EEG unit and proceed to try to induce seizures. The seizures are recorded to monitor any physical happenings during the episodes. In many cases, the doctors will see the signs of an oncoming seizure before the patient does. The brain waves begin to increase quite rapidly. When my seizures started, the nurses would come into the room and begin to time the episode. They'd give me a password, any word, just to see if I could retain any information. They'd ask questions and wait for me to respond.
I currently go to the Cleveland Clinic in Florida and soon I will be having surgery at the main facility in Cleveland. Best of luck and remember to do yoiur research! :)
