Dear Janet, In reading your latest post I remembered some thing that happened years ago that you may think supports your theory of brain cell inactivity vs death. About 13 years ago when I was most actively pursuing THE answer I had a consultation with a massage therapist by the name of Ben Bengaman who had the status of guru. Had published his own book and ran his own school He diagnosed my early PD symptoms as "shredded cervical ligaments" and suggested that I go to LA or SF to see this New Zealand born and trained ortho. surgeon who would inject a solution [Saline] into the damaged area. The ligament was then to regenerate. It would take many injections,many plane rides cross country and lots of $$$$$$$. I declined. But I bet he would share your view. george
