Multiple sclerosis (MS) remains the major cause of neurologic deficit and disability in young people—those who are establishing themselves professionally and personally and generating a reserve that is to support them and their families throughout the rest of their lives. Disruption at this stage of life has wide-reaching consequences for them personally, their families, and their professional colleagues, affecting all levels of performance.
