Is Parkinson's an auto immune disease? We tend to think not because aside from having something that deteriorates as in the myelin sheath of MS. We have cells that are dying off. What if that dying off process is the body attacking those cells in the SN? There could be some sort of trigger or various triggers for that matter albeit environmental or otherwise that add up to "pull" that trigger then the dominoes start to fall. Oh well just thinking. HHHHMMMMMMM.
Then maybe some of the treatments for an autoimmune disease may work. No?
