A Complex Task Using Symptoms, Neurological Exam, and Imaging Tests.
Diagnosing multiple sclerosis (MS) is complex and challenging, mostly because MS symptoms are unique to each individual, and they can mimic those of a number of other diseases. In addition, there is no single blood test or imaging test for diagnosing MS.
Today, neurologists use the McDonald Criteria to diagnose MS. This set of guidelines was revised in 2010 to incorporate MRIs into the diagnosis process, actually allowing MS to be diagnosed earlier in some people.
The McDonald Criteria for Diagnosing MS
The McDonald Criteria revolve around the presence of MS relapses, also known as attacks, flares, or exacerbations.
