[note - @Allyson posted this link in another thread but I thought it was worth repeating here in the POTS section]
Dysautonomia International blog entry about recent POTS research:
http://www.dysautonomiainternational.org/blog/wordpress/new-evidence-of-autoimmunity-in-pots/
From the first paragraph:
Later on in the article the Dr. David Kem does a nice job of explaining the issue. And he mentions how it might eventually lead better testing as well as treatment. Obviously, more testing is needed first.
If I understand things correctly (and that's a big "IF" ), it looks like this research into adrenergic autoantibodies applies to both POTS *and* NMH (and/or Chronic Orthostatic Intolerance --- so many names for all the various orthostatic issues!). The article talks about how these adrenergic autoantibodies cause changes to heart rate and the constriction/dilation of blood vessels.
In short, it might be interesting reading even for those without a specific POTS diagnosis.

From the first paragraph:
Researchers from the University of Oklahoma and Vanderbilt University have identified evidence of adrenergic receptor autoantibodies in a small group of POTS patients, suggesting that POTS may be an autoimmune condition in these patients. The study was published in the Journal of the American Heart Association (JAHA).
