That's me. I was diagnosed in 1990. My first MRI came up clear (of course MRI was in it's infancy back then, but still), and my diagnosis was based upon recurring MS-like symptoms and a positive evoked response test.
Ever since then, I've probably had 4 more MRI's - always comes back "normal brain", yet my neuro stands by the MS diagnosis. He's one of the top MS doctors in the country, so I am OK with the diagnosis - but am I the ONLY person on Earth who has MS, but good MRI's?
