I understand your concerns. Even though I had a brain tumor in my left temporal lobe and intermittent Sz, the EEG showed nothing but a "sleepy" concern. I understand from my neurologist that the EEG will not in a few moments regard the SZ unless you are actually having that type at the moment. I had partial seizures affecting my memory and speech since it was in the left temporal lobe...now that I am tumor free, I am still on Keppra...and still 6 weeks later having some difficulty in my speech and memory from time to time. I did have loss of time before and episodes where I "slept" for a few seconds or minutes...and according to some just had open eyes and stared, but I could not remember it. Perhaps a longer sleep study as indicated by our other friend here will be helpful as well..I know...I miss driving so much...it is so difficult having seizures and losing some of our comfort zones.

Wishing you the best!! Joanie
