The article, “The Cost of MS Drugs” in the December 2011/January 2012 issue of Neurology Now states, “But if the disease progresses to secondary-progressive MS, that person will experience more frequent episodes of illness.” This is incorrect: a person with secondary-progressive MS does not experience more frequent flares but rather has a gradual decline in their illness due to the nature of the disease being more degenerative rather than inflammatory.
