The fact that symptoms flare-up and subside for many people with multiple sclerosis (MS), combined with the wide variety and unpredictability of symptoms, has made MS a difficult disease to recognize, define, and treat – right from the start. Since the late 1300s, individuals with a progressive illness suggestive of MS have been observed. It wasn’t until 1868 that the famous neurologist, Jean-Martin Charcot, lectured on the features of MS and gave it a name.
