Jessica, I've not noticed any on-list answers to your question, but there are several ways of measuring the progression of PD commonly used, I refer you in particular to: http://www.fortunecity.com/meltingpot/farley/817/ameasure.html But don't give up hope - the scientific community is making progress, and we expect a cure in the near future - hopefully before your father - and indeed I - get to the worst stages. Our Dallas support group, DAPS, has produced a tape, "A Story of Hope," which you might find of interest. Formal free distribution of this tape is over, but we do have a few copies available still at no charge for those who might find it of interest and who request it, sending me their snail-mail address.
