"but where every part of the body looks completely normal under examination"
...is this talking about physical examination (i.e. inspection, palpation, ... ) or special investigations, because I think that many functional disorders do not appear to be functioning normally when the correct testing is used, usually physiologic imaging and things like that. I think the definition should specify that anatomy may be statically normal, and yet appear abnormal during function. Just a thought... Lesion (talk) 02:08, 16 March 2013 (UTC)
Agreed. Physiology > anatomy. And MRI/CT/E(C,H,M/G/etc. >> GP (alas, the latter is what you get most of the time). This should be emphasized in the article; that this umbrella term is more a hiding place for ignorance/unwillingness to put a patient under "real" examinations, rather than just the GP's short glance at a patient. --18.104.22.168 (talk) 05:22, 24 March 2013 (UTC)
Agreed, the definition doesn't make sense - is diabetes a functional disease? Is early dementia a functional disease? Erectile dysfunction? (not so long ago it was thought to be exclusively psychiatric) Is restless legs a functional disease? Is essential tremor? ~~ — comment added by 22.214.171.124 (talk) 15:47, 5 October 2017 (UTC)
