“Most people with MS experience their first symptoms and are diagnosed between the ages of 15 and 50, although individuals of any age may be diagnosed with MS. More women are diagnosed with MS than men, and the area where someone lives, as well as race and ethnic background, also helps to determine his or her risk of developing the disease.

Nearly one million individuals are living with MS in the United States. This new prevalence figure was published in 2019 and is more than double the previous estimate of 400,000 affected people in the United States.”
