I have some questions for anyone who might know something. My mother is comtemplating DBS surgery of the type where the Medtronic device is the one used, along with the bilateral implants. Does anyone on the list know a neuro surgeon named Ron Alterman MD. He is on the staff of Beth Israel Hospital in New York City. All input greatly appreciated. Thanks.
