Hi to all It makes sense to me Janice 51/6/1 -----Original Message----- From: Lanier Maddux <[log in to unmask]> To: Multiple recipients of list PARKINSN <[log in to unmask]> Date: Saturday, October 03, 1998 9:06 AM Subject: Re: Should we change our Identification Formula? This idea makes sense to me, I started out using date of first symptom, which in my case was very clear, the tremor started up just like someone had turned on a switch. But then I thought most PWP's were using date of diag, which in my case was one year later. I had thought of this myself but did not say anything about, so I am glad that Ivan brought it up.
