Your experience represents more definite positive results than mine. It appears that you actually dimished in motor symptoms rather than just arresting progression. Overall, i'm convinced that low dose DM shows the best promise in neuroprotection.
A few weeks ago I emailed the local movement disorder specialist, who is also a member of the Parkinson's Study Group, complaining that I felt the NIH is wasting its money with neuroprotection studies on things like creatine instead of more promising drugs like dextromethorphan and naltrexone that have already shown some effectiveness. I told him of my experience since beginning DM, and he replied that PD is so inherently variable in it's rate of progression that my experience was hardly significant in the overall big picture. My own neuro is not so dismissive, and could be described as cautiously optimistic about DM.

I would like to hear from others who are using DM or naltrexone in an attempt to achieve neuroprotection and progression arrest.
