I had it done and think it was well worth it. My neuro ordered it but my insurance would only pay for a mini exam. So when the neuro-psych doctor heard I had to cancel it, he did it for free. He said anyone with MS really needed it to not only define areas of dysfunction but could actually pinpoint more exactly in the brain where the defect was. His results really helped me understand that what I was experiencing was really real. I guess what I am saying is that it validated what I was feeling. My first sx were when I was 47, some people are feeling a little old and sluggish at that time and he showed me that a lot was MS. It also helped me because I have only one lesion so I am only clinically probable MS but with the degree of problems that the testing showed it helped my neuro and helped me get my SSD. So go for it. I'm an RN so I think all kinds of tests are exciting!!!!!
