Thanks for the response

Currently my doctor will not advocate any treatment / therapy until he receives guidance from a specialist as to which way to treat me. At the moment I am being treated for "headaches" despite displaying other symptoms. His advice is to only take paracetamol and sit it out. This is literally a painful position to be in as I am stuck in a "no mans" land of not being able to work, not being able to prove I can't work nor have access to any means to get better. With lack of Neurological services where I live in the UK I have two options:

a) wait for the Health service here in the UK to provide me a with Neurologist review. However they want an MRI scan before seeing me. Then they will undertake their "assessment". This is unlikely to happen until November / December

b) To see a private ( where I pay $350 per hour) Neuropsychology who will run some "tests".

The majority of the assessment I have seen examples of are really basic Andi want to analyse mental happiness rather than capacity or capability.

So my question is what are these "tests" and how conclusive are they and from these can they determine a severity / permanency / likelihood of recovery etc? Perhaps hoping for too much
