This wording is totally loaded. If they are genuinely saying the conditions covered are suspected of having a neurological basis which the title implies why (ok we all know why) are they then saying in the body of the text that:
1 they don't have any medical basis = well there's all that biomedical research going on but we still think we can ignore it
2 they have an "emotional basis" = well they're all just hysterical
3 they "mimic" neurological symptoms = they're making it up malingerers
4 the "functional" explanation to be given to patients will reduce the overall "load" on the service = bullshit them and they will go away
5 neurological assessment is unlikely to be needed = well they're making it up so why would it
6 If the guidance is on this basis GPs will not refer to neurology = we don't want these people wasting our time with their made up hysterical symptoms
Usual bait and switch of OK let's say "suspected neurological" to cover our backs on WHO classification but actually the text will be all the usual psych rubbish.
Total pile of manure.
