DEBI ,
not trying to be difficult but do you have the link to that 15-17% participating in pd trials not having pd? it would be important to know if that was for the u.s. or worldwide. was that due to misdiagnosis by a neuro or just patients lying that they had pd? is it an old number no longer relevent? i participated in one drug trial for a new agonist and i received a pretty thorough exam to verify i had pd symptoms. also,one has to ask are pd trial subjects representative of the pd population? i don't think they are. i just think there's much more to that factoid than just not having pd.


no doubt better/earlier diagnosis is needed.
