Multiple sclerosis (MS) involves an abnormal response of the immune system that is directed against the central nervous system (CNS). The exact reason why immune cells are sensitized to attack is unknown. If you or a family member is recently diagnosed with MS, please know that you are not alone; more than 2.3 million people are affected by MS worldwide. There are four different disease courses. Each of these courses can be characterized as mild, moderate, or severe. In all types of MS and all severities, it is important that the person has a strong and reliable care team available at all times. Whether you have relapsing-remitting MS, secondary-progressive MS, primary-progressive MS, or progressive-relapsing MS, it is important to eat healthy foods, avoid overexertion, and to stay current on your medications. With a FamilyCARES CAREPARTNER , it is much easier to remain in your best possible state of health.
