'Brain Slowing' Interesting question- There is some recent science showing definite cognitive impairment in PD, but I don't recall any correlation with "on" or "off" phases that are dopamine- related. I should guess it's part of the disease, and not a side effect of medication, but there must be a lot of Ginkgo and St. John's enthusiasts out there who might disagree. Cheers, Joe -- J. R.
