Like Hillary, I thought the second number was years since diagnosis. I had somewhat vague symptoms which I think may have been related to PD as long as 18 years before I had more definitive symptoms. As soon as I went to my GP complaining of the definitive problems (a "twitch" in my thumb, lack of swing in my right arm, etc.), he immediately referred me to a neuro and the diagnosis of "Parkinsons or a Parkinsons-like" condition was made within just a couple of months. I like the idea of the added number; I'm just not sure which I should use. Julie Berchenbriter 50/20/9 (I think)
