I had a seizure last sunday I was sleeping, and I was not on any drugs and did not drink the night before. . It was my first one. I was rushed to the ER, I had a cat scan and an MRI- both came back normal. I had an EEG and it came back abnormal. I met with a neurologist today, and she has no explanation for me, and wants me to get another EEG done.... does anyone have any ideas on what might have caused me to have a seizure?
