I have had many symptoms of MS for years, and there is MS in my family. However my MRIs have reportedly been "normal" with the exception of my last one. It was done on a 1.5 Tesla machine and showed possible demyelination on the right optic nerve. Could this be a sign of MS?
This is a difficult question to answer without more information. The optic nerve is difficult to image by MRI. It is far easier to see abnormalities within the optic nerve when it is acutely inflamed and creating the visual problems we seen in people with optic neuritis, but abnormalities suggestive of MS can be seen even in asymptomatic individuals.
The fact that you have experienced, “symptoms of MS for years” but repeat imaging studies have shown little if any abnormalities consistent with MS is a very good sign. That is really all I can say given the information provided.
