Multiple sclerosis (MS) is a disorder of the central nervous system (CNS) characterized by inflammation, demyelination and degenerative changes that can lead to functional loss and disability.
Most people with MS experience relapses and remissions of neurological symptoms, particularly early in the disease, and relapses are usually associated with new inflammation in the CNS. Over time, there are fewer relapses and less new inflammatory activity with the disease process becoming more progressive. There is a large body of evidence that supports early and ongoing treatment with an approved disease modifying therapy as an evidence-based approach to reducing new relapses, delaying progression of disability and limiting new inflammation in the CNS.

FDA-approved disease-modifying therapies (DMTs)
The FDA has approved several disease modifying therapies for the treatment of relapsing forms of MS, which include clinically isolated syndrome, relapsing-remitting disease (RRMS) and active secondary progressive disease (SPMS with relapses). One DMT has also been approved for primary progressive MS and one other for non-active secondary progressive MS (no inflammatory demyelination or clinical relapses).

American Academy of Neurology Practice Guideline for the Use of DMTs
In April 2018 the American Academy of Neurology (AAN) published a practice guideline
for the use of disease modifying therapies for adults with multiple sclerosis. These guidelines have been endorsed by the National MS Society and Multiple Sclerosis Association of America. The guidelines address starting, switching and stopping disease modifying therapies for adults with clinically isolated syndrome, relapsing-remitting MS and progressive forms of MS. The full guidelines and summaries are available for clinicians and patients.
