Hello Thank you Barbara Patterson and Janet Paterson for the welcome. My name is Ron Erickson. My brother has Parkinson D. It began nine years ago. It is now quite severe. He has had two bad bouts of depression. Most medications have only been marginally helpful. He has approval now to use Tasmar. If that is not efficacious he most likely will try a Pallidotomy. I would appreciate any comments on both the Tasmar and the Pallidotomy. Also if anyone has a list of the hospitals and surgeons that do the operation, that would be helpful. I have a partial list. My brother lives in Cando N. Dak.. about a days journey from Minneapolis (my location). He is considering the University of Minn Hospital for the surgery, if it comes to that. Thanks for any info you can give me Regards, Ron Erickson
