Altho it may not initiate with an autoimmune event, pd appears to be very autoimmune in nature. Would it be useful to sort out which symptoms are autoimmune and whichare not? i don't like to be manipulated into group activity but the brain power and sheer number of posters might yield something new:

ok i could say so many but would rather others think about it :
[please correct errors in any of the posts.]

protein malfunction [try to find others besides alpha synuclein]
apoptosis
aceptycholine, glutamate, ,mao, and more are toxic in large quantities
gaba and norepinephrine are low, leaving no brakes , not enough adrealin, effecting serotonin.and and cause an abundance of the toxic transmitters.

i'll stop there but are those chemical imbalances all caused from autoimmunity?
