Could someone help me understand where we stand with PD research? I have spent the last many years reading about electrical therapies for PD, drugs for PD, cellular therapies for PD, growth factors for PD, nutrition-based therapies for PD, fecal transplant possibilities for PD, and on and on. While I tend to want to believe PD could be helped or even cured by food/nutrients/good gut bacteria, that possibility does not reconcile in my mind to the fact that DBS and tCMS help PWP (if the cause were nutritional deficiency/ies, wouldn't sending current through someone's head do nothing? and yet so often it helps!)

It seems that the more I read, the less I really know and the more confused I get! I guess I should be grateful that PD is being researched on so many diverse fronts, but still...
