I am a new subscriber writing in response to Barbara's welcome. My interest in Parkinson's is not professional (I teach Philosophy and Classics in Frederickburg, VA), but personal. My father, a retired pediatrician in Wisconsin suffers from the disease. He is primarily affected by instability and lack of mobility. He has good days and bad days with no predictable pattern. On the bad days his window of activity is limited to 3 or 4 hours in a 24 hour period. I joined the list hoping to learn more and to be able to rely information to my parents. My mother is particularly interested in any information relating to diet and nutrition. I heard recently a new report about studies on the rati of protein to carbohydrates, I believe from Boston U (?). If anyone could point me to a source for more specifics, I would be grateful.
