Let me first say how much I appreciated the Martone biographical sketch posted. I especially appreciated the analogies used and the effort made to communicate in lay persons terms. However, for the sake of correctness the Pallidotomy is a surgical procedure on the Globus Pallidus not the Sub Thalamus. Although some surgeries have been performed creating lesions in the Sub Thalamus this is definitely the surgery of choice. Plus, I would raise the issue about the Pallidotomy surgery being a higher risk than a transplant. As one who has had both an adrenal transplant in 1987 and a Pallidotomy in 1993 there was no comparison as to which surgery was the less traumatic and hence less risky. As far as effectiveness the Pallidotomy is also much superior to both fetal cell and adrenal cell implants Dr. Don Berns 4943 Del Monte Rd. La Canada, CA 91011 818-790-8812 <[log in to unmask]>
