Symptoms are diagnosed as other things early on (a pinched nerve leading to numbness, vertigo from a ear problem, etc), and since they let up after the exacerbation, its not until the disability starts to accumulate (which may be later in the disease) that the idea its actually a neurological problem surfaces and someone orders and MRI of the brain and spinal columnMLS
Thanks for the information, I have a close friend who was diagnosed early on and it turned out to be an accurate diagnosis, fortunately. I didn’t know there were many cases as you describe.
