The National Multiple Sclerosis Society (NMSS) is an organization with a network of chapters throughout the US. The organization's goal is to move towards a world free of multiple sclerosis, a debilitating disease that attacks the central nervous system. Over time, those suffering from MS become less able to move and function on their own, which is why the Society seeks to fund research and develop medications to both treat and cure MS.
