"Participants with MS will be divided into two treatment groups: those who will begin to take Ocrevus (the early Ocrevus group (EO), and those who plan to be begin treatment with Glatimer acetate SC (Copaxone) (EC). Both groups will be matched to the EO group for age, gender and education. The HC group will be free of neurological disease or injury and will be matched to the EO group for age, gender, and education."
