The Parkinson's enigma

Description

Using the illness of Michael J. Fox as a springboard, this program theorizes that most Parkinson's cases are the result not of heredity but of viral attacks and environmental toxins that severely damage the substantia nigra, the "gearbox of the brain." Fox, Oliver Sacks, neurologists from The Parkinson's Institute and The University of British Columbia, and others share insights drawn from their knowledge of Parkinson's, encephalitis lethargica, Guam disease, and MPTP poisoning that, taken together, make a compelling argument for linking Parkinson's to neuronal trauma. Therapies involving neuronal grafting from fetal tissue, retinal pigmented epithelial cell implantation, and transplantation of adult stem cells are discussed as well.
