Multiple sclerosis (MS) affects more than 2.5 million people worldwide, and in the United States alone, about 200 new people are diagnosed each week. Those are just a couple of the many reasons why the Multiple Sclerosis Association of America (MSAA) recognizes March as Multiple Sclerosis Awareness Month.
What more do we know about MS? Doctors are unsure of the root cause of the condition, but women are twice as likely as men to develop MS. Additionally, the farther away from the equator you live, the greater likelihood you’ll experience MS – overall, your lifetime chance of developing MS is about 1 in 1,000.1
Did you know that there are four different types of MS? Each one affects people a little differently.
Share this post on Twitter and help spread the word for MS Awareness Month.

- Relapsing-remitting MS (RRMS) affects the large majority (85 percent) of MS patients, and this type features clearly defined periods when symptoms get worse and activity decreases.
- Primary-progressive MS (PPMS) causes a clear progression of symptoms and equally affects men and women.
- Secondary-progressive (SPMS) is a form of PPMS which is initially diagnosed in only about 10 percent of patients.
- Progressive-relapsing MS (PRMS) is found in only 5 percent of MS patients, but these people have both clear relapses and a clear progression of symptoms.
