Have you studied The McDonald Criteria?
"The McDonald Criteria was first established in 2001 by neurologist Ian McDonald and a team of researchers as a standard means of diagnosing multiple sclerosis (MS) with sensitivity and speed. (It is also known as the International Panel on MS Diagnosis, and the original and subsequent panels were, at least in part, organized by the National Multiple Sclerosis Society.)
The McDonald Criteria is distinguished by incorporating clinical evaluation with magnetic resonance imaging (MRI) scans in establishing MS."
