16 years ago i had 2 ideopathic seizures.Had all the tests. Put on Dilantin. Inquired about the origin of my seizures with my neurologist. Told we would never know. Took meds religiously. No seizures for 16 years---until a couple of weeks ago. Had a grand mal, stopped breathing, rushed to hospital. Told to take more Dilantin[4200 mgs a week]. Had MRI---showed non specific white matter. Saw seizure specialist,she suggested cortical dysplasia. Is this epilepsy? How unusual is my case? What is the likelihood that I'll have another seizure? Recently put on Lamictal as well as Dilantin.Help!
