Hot off the press, a brand new article published this week called: “Experimental evidence for a robust, transdiagnostic marker in functional disorders: Erroneous sensorimotor processing in functional dizziness and functional movement disorder”
As the authors state, the results “point towards a general central dysregulation affecting sensorimotor control, where internal model representations of the body are erroneous and not updated appropriately.”
The authors also state that the changes are from, “fundamental, automatic, objectively measurable processes in the central nervous system (CNS) and not from explicit expectations or conscious decisions.”
Tiny sample size and, as far as I can tell, little understanding of what can cause symptom fluctuations in people with so called 'functional' dizziness which will impact trial results if they are not factored in.
As it is, 'functional' dizziness is being massively over diagnosed, sometimes on the basis of a second episode of 'dizziness' alone and before people have even walked through the door, and no attempt has been made to capture the misdiagnosis stats of what is considered to be a subset of FND.
It is an interesting paper but they needed a much, much larger sample size.
