infantile spasms

hi I am a grandmother and my granddaughter is 10 weeks old and having infantile spasms and they are not able to get them under control. We are looking for information on Where the best neurology pediatric hospital is so we can try to get more help for her we live in the state of NY can anyone help us. The doctors told us the baby as an adult will be at best that of a 5 to 12 year old. We are so new to all this and need more answers.
