Please realize this is a laymans understanding of what several pallidotomy centers consider. 1. Idiopathic(typical) Parkinson"s Disease for several years. 2. Initial response and still some response to levodopa. 3. Sthe ablity to walk in on state. 4. Adequate health with no severe low blood preesure, or other major problems(respiratory problems would be a possible problem.) 5. No Dementia To this I think you should consider --- Are you ready for Surgery?Are your symptoms significatant enough that they are almost unbearable/ If you wait, will your health be good enough to have surgery at a later date? The longer you wait, the more will, be known about PD and surgery. Newer procedures such a s stimuation will be developed and improve. Are you symptoms the symptoms surgery will help? When it is time for surgery for you, go ahead. Have the surgery. Several centers now have the skills and experience to do it. If you are a proper candidate for surgery, you can expect a tremendous improvement in your daily life. Don Connell [log in to unmask]
