As you noted, the scientific debate over when to start levodopa is long and far from settled. The evidence against is mainly from tests on cultured cells in petri dishes, while the evidence pro is from long-term followup of various trials on rats and people. The trial you refer to was the first, described in the documentary film "Awakenings", which I recommend. Cheers, Joe J. R. Bruman (818) 789-3694 3527 Cody Road Sherman Oaks, CA 91403-5013
