Given the fact that PD drugs leave a lot to be desired, far be it from me to stop using them and begin taking Coenzyme Q10 based on such a small study which appears to be somewhat inconclusive. I am on Sinemet and Mirapex and was diagnosed four years ago. I would be truly wonderful if it were as simple as taking an over-the-counter drug which at least slows the progression. But I for one, need more concrete statistics.
