MS is described by the National Multiple Sclerosis Society as an unpredictable and often crippling disease of the central nervous systems. It disrupts the flow information between the brain and the body. Although the cause of MS is not known, it is thought to be caused by a combination genetic and environmental factors. According to the organization, there are approximately 1 million MS patients in the United States at this time.

Applegate isn’t the first celebrity to publicly share a diagnosis of MS in recent years. Applegate’s announcement was preceded in part by her “The Sweetest Thing,” co-star Selma Blai, Jamie Lynn Sigler, former talk-show host Montell Williams, and Jack Osbourne, reality star.
