Many here have commented on PD being an autoimmune disease...
I didn't really understand what that meant, so have been doing some looking into things.

Here is a roughly 10-minute video of Dr. Trevor Marshall discussing autoimmunity: http://www.youtube.com/watch?v=hcAVeKobsxU

It is very interesting because it goes hand in hand with several observations one can make simply by reading comments and anecdotes from PWP:

different symptoms for each person with some similarity
severity of symptoms different for each person
consistent reports of symptom improvement with use of antibiotic (for other, non-PD reason like infected tooth, etc.)
why drugs do not cure us or even stop progression
why we get worse (pathogen is becoming more prevalent, weakening the body)
why, given the "inponderable complexity" of the interaction of the many pathogens in even healthy people, pills will never be the path to recovery

We are seriously looking into Dr. Marshall's protocol, it may seem complicated but really is not. It is, however, long-term and that in itself is daunting. Has anyone tried it and if so, what happened? There are lots of positive reports for it working for people with other conditions, but I have not been able to find any anecdotes of anyone using it for PD. Please share if you have any experience with this.
