Parkinson’s Disease What the Movie Illustrates:--Movie illustrates how discovery of this neurotoxin has stimulated research to understand and treat a very common nervous system disorder.--It vividly illustrates what this disease is like.--It presents the ethical and political controversy surrounding fetal tissue (& stem cell) transplants.
