Anyone know of a pediatric neurologist in the Chicago area who is knowledgable about moyamoya and a bonus if they are also good with neurofibromatosis?  
I have a nephew who was dx with NF1, but his doctor at the neurofibromatosis clinic didn't think he needed to see a neurologist or have any imaging even though I have mm and he has experienced numbness and headaches (NF and MM have shown to have some relation - our family also has hemochromatosis - good grief, how many weird genetic mutations can one family have???!!)
I really want him to see a neurologist, but I want to make sure it's someone who is going to take it seriously and not be dismisive about my sister's concerns.  Any suggestions would be appreciated.
