Hi Sharon,
Welcome to our moyamoya family. I’m so sorry to hear that your daughter may have moyamoya. You just brought back a memory of myself when I first heard the words moyamoya. I contacted DJ, and I think I said, “someone please help me!” So I sure do understand, we all do. Everyone here has been through what you’re feeling and had the same questions, and we’re here to help you in anyway we can.
First, you’re right to learn all you can about this disease. It’ll help you make informative decisions along the way. That’s so important!! This is a rare disease, and not many doctors know about it, let alone have experience with it, so you need to know all you can about it, so they can’t steer you in the wrong direction, as we see all too often. Which leads me to another very important factor, if not the most important, and that’s choosing a doctor with experience, and hopefully, a MM specialist if at all possible. There are so many factors involved with MMD, and a neurosurgeon with experience is imperative, IMO. Unfortunately, there are only but a few MM experts, who deal with MM on a daily basis, to choose from. The two that have the most experience, IMO are, Dr. Scott, at Children’s Hospital in Boston and Dr. Steinberg, Stanford, CA. When your daughter’s diagnosis is confirmed, you should get a second opinion from the best. You can overnight copies of the MRI/MRA and Angiogram (the definitive test to confirm MM) to an expert ASAP. For example, Dr. Steinberg, who saved my niece’s life, got back to us within hours of receiving the films with his expert opinion, at no cost. It saved her life, because the doctors here wanted to wait.
See, MMD is a narrowing of the arteries to the brain, which robs the brain of the vital blood and oxygen it so desperately needs. Your brain makes up for it, and grows new vessels (collaterals) to try and give the brain the nutrients it needs, but these new (MM) vessels are abnormal and weak and can rupture at any given time and cause a stroke. There lies the danger, and the importance of an experienced doctor.
This is a lot for you to absorb all at once, I know, but thank God, there are answers for you and roads to take, and we’re here for you every step of the way. If you find this all over whelming, and would like someone to talk to, I would be happy to listen and help you in any way I can, as would many others here. They are wonderful people here, God love em! Just let us know or ask away. No question is too small. If you can't sleep, I'll give you my phone number in a private message or vice versa, just lemme know.
In the mean time, please know you and your daughter are in my thoughts and prayers.

Mar
