hi rappleman,
I don't think anyone will be able to answer that for you accurately. Most neurologists recommend holding off on l-dopa and using the agonists. This makes sense and one can only wonder how those who waited would have done had they started sinemet from day 1. The opposite is true as well, those who started on sinemet can't go back so we can only compare similar pwp on sinemet from day 1 vs on agonists until they had to go on sinemet.
Finding similar pwp requires more attention to details in current day thinking as they search for subtypes of pd. So for example, i wouln't compare a tremor dominant pwp with a rigidity dominant one.
i can tell you my experience. i had a neuro who adamantly does not prescribe sinemet until he has tried everything else. This way I managed to last 6 years post diagnosis on agonists and anticholinergics and at least 3 years with symptoms before diagnosis [denial ] with no med before i went to a neurologist. So i feel very comfortable with the fact that i have had pd for at least 3 yrs [probably more] prior to dx.
So that means now i've been on sinemet for 11 years but also had pd symptoms for 11 years before I went on sinemet. i became dyskinetic almost right away. I have it somewhat under control with amantadine.
The problem with sinemet doesn't stop at dyskinesia and this reason even more than dyskinesia makes me obligated to speak out about it. Sinemet stops working after awhile and life becomes a big medicine juggle. Then you add more med.
My speech is ok in the mornings, but as soon as the sinemet builds up everyday my speech goes very faint, becomes very slurred and it races. I can outtalk anyone when my speech is racing.
Sinemet changes your personality too. But it works, i 'll never forget the relief i got immediately from sinemet. Unfortunately it doesn't last without modifications. There are people here who have taken sinemet since day 1 and 15 or more years later they are still doing fairly well.
as with everything it seems concerning pd - no one knows for sure,
but hope this helped some. the only thing they seem to know for sure is that exercise is imperative.
