Discontinuation of Disease Modifying Therapies (DMTs) in Multiple Sclerosis (MS)

Participants will be randomized (1:1) to one of two groups. One group will stay on their current MS medication (Continue group), and one group will discontinue their medication (Discontinue group). They will also have some extra assessments done at their regular routine MS clinic appointment and every 6 months for the next 18-24 months. The following items will be done in addition to any assessments or procedures they are already having done as part of their clinical care: * Questionnaires about the participant's quality of life including questions about health, mood, thinking, and social life * Questionnaires about the participant's MS symptoms * Test of the participant's attention, concentration, and thinking * Test of the participant's physical symptoms * In addition to any MRIs the participants may get as part of their routine care, they will also have an MRI 6 months from their enrollment into the study.
