A.B. said: @Large Donner , the term functional status refers to ability to carry out the tasks of everyday life. Take a shower, clean the house, work or study, buy groceries, have a social life, and so on. It has nothing to do with functional disorders. Click to expand...

Yes but if you don't have a mental health diagnosis or an organic proven disease, as according to the CDC, and the very definition of ME/CFS pretty much all around the world exactly who has a functional disorder according those very alphabet organisations?When a doc tells you you have a functional issues or talks about your functional status in the absence of organic disease it means one thing only."Functional" is the third way but has all its routes in neurasthenia, psychosomatic, hysteria, conversion disorder etc etc.Speak to a neurologist and talk about your functional status being as impaired as someone with MS and that you dont have "objective proof of disease" you will most likely be told to try CBT.
