An EXCELLENT documentary was done on this story: I remember seeing it in my undergraduate Pharmacology and Neuropsychology courses. It also was like a mystery thriller: What was triggering those parkinsonian symptoms? What was its chemical structure? How was it made? I do not remember the title, broadcast information etc. Does anybody? (I am trying to find it so that I can watch it again). Natalie Kontakos ([log in to unmask]) THE CASE OF THE FROZEN ADDICTS reads like a mystery thriller and the cases on which the book is based provided the first real insight on understanding PD. It's worth reading.
