I found this website in which patients report their progress when taking a specific kind of drug. I found this result for rasigiline:

I am still trying to figure out how to get an idea how I could get a picture of PD progression and whether there is some slow down. If people would keep track of their scores at several time intervals I could compare this trial with other ones and get an idea.
