I've been thinking about this overnight. It's worth noting that John Simper, the protagonist in this article, was diagnosed 26 years ago. I'm not sure what the state of play was in 1980 with MRI scanning - certainly it cannot have been as good as it is today. There have been I'm sure many misdiagnoses, I suspect recent ones are "safer".
So what do we conclude from the story. IMHO John was diagnosed and likely had a neuro that wasnt much interested in MS so he was, like a lot of us IMCO

, written off. In those 26 years, if my experience is a measure, he would have had no more than 30 ten minute consultations always ending with a pat on the back and "see you same time next year". And it leads me to think I should start to look for an MS Specialist.
