Over The Last Four Months I Have Had Four Incidents

Over the last four months I have had four incidents where I become very confused for days, cannot figure out how to do the most routine tasks. I loose days. I had one seizure with an episode about a month ago. eyes rolled, body stiffened, little foaming at mouth. I am 53 yrs old, good health, 5'1, 116 lbs. Do not do drugs, and have been completely sober for one year next week.
