Check out Dr. Richard Penn at Mt. Sinai in NY. He recently moved there from Rush in Chicago where he performed biSTN operations. My brother was the very firs in April of 1998. Charlie Meyer (of this list) had it about a year later. Dr. Penn, IMO is an excellent surgeon.

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. Renee part/time cg for Judy (75, 65, 63)
