This is a pilot study evaluating the feasibility of a mobile application "myMS™" to collect active clinical tasks (questionnaires, 6Mapp™, COGapp™, VISapp™), magnetic resonance imaging information and conduct genome-wide association studies in subjects with multiple sclerosis. Participants will be self-referred to this study from different sources; patient advocacy groups, social media tools, clinicaltrials.gov, and flyers.
