Pretty interesting opinion piece. Final author listed is Dr. Blair Grubb.
here is an quote from it (my bolding):
In summary, diagnostic criteria for POTS and other common autonomic disorders have been established and are vastly different from the diagnostic criteria of FND (Table 1) (6)(7)(8)(9).Pathophysiology of and therapies for POTS and FND are also vastly different. Taken together, we emphasize that POTS and other common autonomic disorders are not FND and are not "functional" in etiology. Additionally, we believe that uniformly recommending FND-targeted exercise for patients who are misdiagnosed with FND or diagnosed with FND in conjunction with an autonomic disorder, is inappropriate and not in line with the current diagnostic criteria and scientific evidence.
