I think Mr. Here-Now makes very pertinent points about inflammation being a key cause of PD. He mentions several factors which can cause inflammation and the anti-dotes, aspirin, magnesium, vit-C etc. which reduce it.

The great scientific minds have not yet come forth with a significant PD treatment outside of L-dopa and maybe DBS. Until then, you are on your own so taking inflammatories is well worth considering.
