I'm 43, a regular cyclist and runner. Yesterday, I was taking a lunchtime ride. My buddy and I stopped by his daughter's school so he could deliver some medicine to her. He went inside, I stopped my bike. The next thing I remember is becoming alert inside the nurse's office at the school. Apparently EMS had been contacted and checked on me while I was unconscious (I have no memory of that). I gradually became aware of where I was and what date it was, etc.

My wife took me to the ER, where I received an EKG and CAT scan. Everything showed as normal, so the attending physician diagnosed it as a seizure, and referred me to a neurologist. I haven't seen the neurologist yet (hopefully next week).

Question for those of you who've been around epilepsy for a while: is it possible this is a one-time event? I've never had anything like this happen before, and I didn't see it coming.

I felt fine, and was looking forward to a nice ride. Apparently a witness told the school nurse that I slumped forward while I was standing with my feet on either side of my bicycle. Then I fell over to my left side, and was drooling. I was wearing my bike helmet, so that may have kept me from hitting my head. I can tell from soreness that I landed on my left buttock.

I guess I was out for five minutes or so. I had no idea where I was or what date it was. Weirdest feeling ever.

So, now I'm concerned about cycling and driving and a million other things I do daily. What are the chances this won't ever happen again?

Thanks~David
