Hello "threesteve," On 4/16, you wrote, "my grandfather had diabetes and my father now has PD." What wold be very helpful, as I accumulate family histories of PWP's (people with Parkinson's), is if you would let me know whether the maternal or the paternal relatives is/was affected. So, in your case, which grandfather? I agree that anyone who wishes to respond, even if there is no diabetes, hypo- or hyperglycemia, or other blood sugar condition in any relatives, should add to my data base. Thanks for your response!
