Multiple sclerosis cases on the rise nationally
A recent study shows that the number of people living with MS is on the rise. A recent MS Prevalence Study funded by the National Multiple Sclerosis Society shows that in 2010 the estimated 10-year prevalence of adults in the U.S. was 727,344 cases, not the 400,000 that had previously been thought. In addition, the study shows the prevalence of MS cases from 2000 to 2017 is now estimated at 913,925 cases, though that number may be as high 1,000,000. Dr. Robert P. Lisak, who specializes in neuroimmunologic diseases at Wayne State University School of Medicine, said that an initial increase in the numbers of people with MS was thought to be because of better diagnostic tools and more awareness of the disease. "But over the last 10 to 20 years we think there are more cases," Lisak said, though nobody knows why. The problem is if you don't know the cause of the disease you can speculate all you want, but you don't really know," he said. "But there is probably no one single cause or one single risk factor," Lisak said. Lisak said there are new medications out that delay or even prevent progression of the disease. But researchers still need to find out what ultimately causes MS — the mechanisms of what causes attacks, what causes attacks to shut off and what causes progression. Until that is known it is hard to develop therapies, he said. "We need to get more basic knowledge in order to make further progress."
