there is no specific test for this, it is a matter of illimination of known dx's which exhibit the same symptoms which a dx is supposedly based on though mine was given before the necessary tests to illiminate other things were carried out!

it would be helpful to have a dx though if your symptoms have just begun as this should give you a good chance of recovery because treatment should be talking therapy and physio therapy running paralell for many months starting very soon after onset of symptoms, if symptoms last over a year then chances of full recovery are greatly diminished.

I have found my diagnosis has made getting the help and support i need extremely difficult and in some cases impossible to get. because it is classed as a mentel health condition i am being treated under the mental health team who have very little knowledge or resources to treat the physical difficulties associated to this condition and the physical teams will not take me on as i do not have a recognised physical condition just the physical symptoms of a mental health condition! so where others who have lesser mobility diofficulties than myself have been supplied with electric wheelchairs and had their homes adapted before they leave the rehabilitation centre I have had to buy my own mobility scooter (i can't afford an electric wheelchair), had no rehab to help me adjust, and have been fighting for four years to get my home adapted and have to pay for most of it myself when it is eventually done!
