I’m sorry to hear of your diagnoses, but am glad you will have a treatment that will help. There is no set treatment for what my husband has.
As for his MRI and lesions , they claimed all of his lesions appeared at the same time within a month by the way they “lit up”on the MRI. He had no older lesions Where as in MS lesions appear differently. Some are older and some are newer, but don’t appear all at the same time. I know it’s hard to understand!
It’s been a long and confusing journey for us.
