People experience the symptoms of multiple sclerosis (MS) differently. And the course that these symptoms may take has been used to describe a few different types of MS. Here are certain types of MS that impact the body in different ways:

Clinically isolated syndrome (CIS)

CIS is a first episode of symptoms caused by inflammation or damage to the nerves. This lasts at least 24 hours and may develop into MS.

Relapsing-remitting MS (RRMS)

In RRMS, also sometimes just called relapsing MS, new or more symptoms can appear. This is known as an "attack" or a "relapse," and is followed by a period of recovery or "remission." A remission is when symptoms partially disappear or go away completely. About 85% of people newly diagnosed with MS fall into this category.

Secondary-progressive MS (SPMS)

RRMS can transition to SPMS, a condition in which the disease tends to progress more steadily. There are two stages of SPMS—active and non-active. This means that people can develop SPMS with or without relapses. Some people with RRMS may transition to SPMS at some point in the course of their disease.

Primary-progressive MS (PPMS)

With PPMS, disability tends to worsen over time without an early relapse or remission (although there may be an occasional relapse later on). About 15% of people with MS are diagnosed with PPMS.

Be sure to ask your healthcare provider about what type of MS you may have.
