Nothing interesting here - I have PD, but there are no known cases of Diabetes in my family history anywhere. Isn't Diabetes an auto-immune disorder. I have been told that I am at risk for Diabetes because (among other things) I and other family members have other auto-immune disorders such as arthritis and thyroid problems. Maybe you should expand your survey to auto-immune disorders. Maybe my immune system has decided that my substantia nigra needs to be eradicated. Ron Reiner 48 PD 9 mos ([log in to unmask])
