GIRIJA has hit the nail on the head in her statement about a "team approach" in treating Parkinson's. This therapeutic move is spreading like wildfire across the nation.
Some have been using this approach for a long time, such as the Northwest Parkinson's Disease Foundation in Washington state:
http://www.nwpf.org/Wellness/Default.aspx They now have a "virtual" wellness (aka online) community along with a well-established multi-disciplinary facility at Kirkland, WA (Evergreen)
Including exercise, physical and Occupational therapies, nutrition, mental health treatment, etc. has greatly improved the quality of life of PWP. I am convinced that such an approach is the way to go that would be of great help for even newly diagnosed.
