I can't access the paper, but my money would be on ME being something they consider a FMD.

Huepe-Artigas and colleagues offer( important )observations on similarities and differences between patients with functional motor disorders (FMD obvious typo it should read as unimportant .

 

This is one of those papers that typifies how some research is only needed because of issues which only exist as a result of serious flaws in the basic premise.

One of the core tenets of FND is that it is a single disease caused by emotional problems disturbing brain function which changes because of brain plasticity.

The different presentations of disease, interstitial cystitis, IBS, seizures, dystonia and so on are because the brain has met them before so uses these old pathways or because they served as an emotional crutch or something. It is difficult to work out exactly what they are trying to say beyond the fact it happens.

Since all these things are one disease there should be no difference between the pathology of seizures or movement disorders.

is a blow to the theory.
