Hi everyone:
Thank you for all the thoughts. I think I get Mar's descriptions now. That seizure could be part of the TIA? That makes sense and something I didn't think of before. I've heard that some seizures are so focused they are called focal or absence seizures and are very minor. But I'm not sure those type of seizures require medication either. Even if they do, I have not had enough to require any --- so far, Dr. Steinberg has said no anti-convulsant medication (thank goodness, I don't know if I could keep track of any more medications!).
Itsme:
As far as the driving goes, here's how I feel about it. After I had my stroke while driving home last Jan, I was very hesitant to drive alone for awhile. But I had to to get back to work, and I thank god for cell phones and technology. I truly believe every moya moya patient should carry a cell phone, esp. if they are driving. I believe it saved my life that day, so I highly encourage it. I agree with Jill, we can't live in a bubble but we can, and have to, take precautions, even post surgery.
The other thing that is clear with moya moya patients is that you have to be hydrated - CONSTANTLY. We believe I had a TIA on the plane partly b/c I was not hydrated enough (we believe that b/c I had no complications while I was at Stanford). AGAIN, every patient is different so it may have nothing to do with hydration but I think in general it is important to stay hydrated all the time. I have a post it note on my front door that says 'CELL PHONE, WATER BOTTLE, MEDS'. Some people never leave home without American Express, I never leave home without those three things.

(Well, generally I never leave without my VISA but you get the idea

). In any case, I agree with the others -- despite needing to take precautions, surgery is still the best option.
