Just keep in mind that the avaerage GP does not have a clue about neurological conditions.
If you are lucky, you have one who will admit that they don’t have a clue about neurological conditions, and refer you on.
If you are really lucky, you get a Neurologist who is thorough.
It is all the tests that help with the Dx, and a good Neuro (the thorough one who wanted all those tests) will look at all the results and then make the Dx.
Stick with that Neuro if you can.
