Hi all, I sent Greg's very interesting mail to our doctor. I am forwarding his response as I thought it might interest some of you. Moneesha The arguments are indeed valid. At the end of the day neurological disease remains a less explored and understood frontier of medicine. I entirely subscribe to the thought that PD is actually a bundle of diseases which manifests itself in similar ways. Our current treatments are not satisfactory for a large number of the people with the disease. The lack of a clear understanding of the brain's functioning remains an immense obstacle. Actually Parkinsonian disease is perhaps the only neurological disease for which there is any treatment at all. Most other neurological conditions can be diagnosed but not treated.
