Hi-
I am glad that the topamax is working for you (I did not have such luck) and that the MRI still looks good. I haven't seen it mentioned on this thread, but some scientists and doctors believe that migraines and seizures are closely related. And I believe it myself. My roommate in grad. school had severe migraine headaches, with auras (lights around things etc...). Her mom had epilepsy. Ironically, after 3 years of being roommates, I was diagnosed with epilepsy after starting to have GMs.
Little did I know that the deja vu, "upset stomach" and occasional loss of time were seizures.
Most of the time my EEGs are normal. Like Dave said, timing is everything. Also, my seizure focus is pretty deep, so the activity is not always caught by the EEG, since they are only on the surface.
Will be keeping my fingers crossed that things keep going well.
Stace
