Your in N.Y.C.? Have you looked into anyone at Columbia or N.Y.U.? If you are close or have the means to get to someone at either,I would try there. I don't know if that is where you may have been. If you want to try there I could try to help you with a doc there. I wish you and your Mom the best. If you feel she needs to see a neurologist you do what you feel is best for your Mom. It sounds like your getting all different answers.
