Dear Jenny,
Welcome to our MM family! I am sorry that circumstances with Daphne brought you here, but am very happy you found us! As you continue to read, you'll find this board to be full of information. Also important, the people here are compassionate, supportive, wonderful people who have traveled this road in one form or another, and love to offer shoulders to lean on.
I can't imagine what you've already endured with Daphne's illness. Good for you to seek another opinion for her Moyamoya! Unfortunately, most of the medical profession is not familiar enough with the disease to know to advise treatment options. You've taken the right steps in contacting Dr. Scott and Dr. Steinberg. They are by far the most experienced neurosurgeons with this disease, and I would trust either one of them with myself or a loved one.
I will speak from personal experience regarding Dr. Steinberg. My daughter was 17 when she was diagnosed. Dr. Steinberg advised surgery within 30 days, as Tara's MM was pretty severe. She had both sides done, a week apart, last June. Our experience with Dr. Steinberg, Teresa, and the entire Stanford staff was nothing short of incredible. While we hope to not have to go through it again, we feel very blessed to have had their expertise and compassion available to us.
As Michell offered, I too am available to try to answer any questions you might have. Please don't hesitate to post again here or to send me a private message if you wish. We live about 1/2 an hour from Stanford, so if you end up coming out here, we'd love to meet you and be of support to you during your stay.
For now, we'll add you and Daphne to our prayers. She sounds like a fighter, and obviously you're not a parent willing to give up! Know that you're on the right track, and don't hesitate to come back here for support, o.k.?

, Jill
