Since it is the dopamine-producing cells of the brain which degenerate in PD, an appropriate treatment for PD would be one which is capable of regenerating these dopamine-producing cells. In fact, this would constitute the only truly effective treatment of PD.
Adult stem cell therapy does exactly that.
Although adult stem cell therapy as a treatment for PD is not specifically targeted per se as an isolated area of research at many of the finest research laboratories, nevertheless, there have been numerous studies conducted by some of the finest researchers throughout the world, from which very promising results have been obtained. Indeed, the transplantation of adult stem cells directly into the brains of PD patients has already been performed and has already shown marked success.
