I had dizzy spells as a child, I'm talking the 1950s.. come to find out it is one of the symptoms of MS... never needed a test for it as the finally subsided.. remember, this is early days of medical diagnosis.. my suggestion is to ask a lot of questions of your primary care provider and to your neurologist.. why do I need this test and what do you think it will provide for my care..

I have vertigo and have some ad episodes but I take medicine for them but yes it related to M.S

Thank you but he ordered the test and never explained it to me. LOL. I will ask him again. :)
