My Brother-In Law has had Parkinson's for 30 Years. He is in his late 50's. He had a thalamotomy at St. Barnabas Hospital in NYC 23 years ago. It was done by Dr. Irving Cooper. It was a successful procedure which is still effective on his dominant side. The disease has progressed over the insuing years and all the neurologists he has seen, over the years, have insisted he was not a candidate for further surgery. Dr Cooper died a number of years ago, but recently my Brother-In-Law insisted that he see someone at St. Barnabas associated with Dr. Cooper. When he saw Dr. Joseph Waltz, who was an associate of Dr. Cooper and assisted at the original operation, we were all shocked to find that the Doctor felt he was a candidate for an additional Thalamotomy. This has left us happy but somewhat confused. I am posting this E-Mail and searching the web for additional information and advise. Anyone who could help in this matter through experience or additional knowledge would be greatly appreciated. Paul Buote
