Hi, Kathleen!

While we see Dr. Scott and not Dr. Steinberg, I can tell you what our protocol has been. My girls both had MRI's at 6 and 12 months, and every 12 months thereafter. For some patients he does angios instead of MRI's, but I think because Cassie had had so many complications following her first surgery, he decided to go with the non invasive procedure, and I was just as happy about it!! They have their MRI"s in the winter, because that's when it coincides with the anniversary of their surgeries - but we don't actually see him. We go in the summer for their annual check ups in the summer so that I don't have to take them out of school another time. SO even though he sees them only once a year, he checks on their brains twice a year.
Our neurologist sees Cassie every 3 mos. mostly because she was on some meds to try and lessen the ADHD symptoms following her stroke - and we can't seem to find any that don't make her BP and pulse go sky high! (Presently we've stopped all of those meds, I'm not going to risk my daughters heart to make things easier for the school!!.......But that's a whole different issue!!

) For Kate, since she's not taking any meds for the MM other than aspirin, the neuro sees her every 6 mos.
I hope that helps. But I agree with the others, if my girls were having the symptoms you're having now, I'd be sitting in the neuros office, not leaving until he saw them.
Good luck! We'll be thinking of you!
Love, Kristen (and the girls say hello, too!
