Hi Therese,
Without wanting to most of us within this group have become very knowledgeable about P.D.
In fact I'd say more knowledgeable than the average Dr because we live with it always and it isn't about to go away.
If we try and ignore it or think we don't have it somehow the P.D. comes back to bite us on the bum!
I don't know much about L.D. so won't try and answer those queries but does Doreen seem better after a dose of Sinemet?
Does her handwriting improve? Cogwheel rigidity lessen? Finger taps speed up?
These are the sorts of things which when the Sinemet kicks in during the early days of a fairly definite diagnosis of P.D. will tend to improve quite dramatically.
Hope this helps.
Lee
