Two months ago my sister, 29, had a seizure, full body shaking and unconciousness, bit her tongue and some memory loss. At the hospital her MRI, EEG, EKG CT scan and blood and urine test all came back clear. The Neurologist said, "well, sometimes this happens." Then a week and a half ago she had one in her sleep, and then another just a few days ago. This time the doctor has put her on Kepra. Again her tests came back clear. What does this mean? Does she have epilepsy? Are there other test she should get to make sure it's not something else causing the problems? And will she have to be on medication for the rest of her life? She's made an appointment with the neurologist from her first seizure, but he can't see her until January. Any thoughts or advice? Nothing in general in her life has changed, other than she just got a dog.
