The main role of immune cells is to recognize foreign organisms, such as bacteria, and protect your body against them. Most experts believe that in MS, immune cells mistakenly attack myelin, a substance that surrounds and protects nerve fibres. Repeated attacks cause inflammation and damage to myelin in the brain and spinal cord.

What are CIS and RRMS?

Clinically isolated syndrome (CIS) refers to a single episode of neurological symptoms suggestive of MS.

Relapsing-remitting multiple sclerosis (RRMS) is characterized by unpredictable but distinct episodes where new symptoms develop or existing symptoms worsen.

• These episodes are also known as relapses, flare-ups or exacerbations. In between these episodes, the symptoms either disappear completely or almost completely.

MS is unpredictable

MS affects everyone differently. Episodes (also referred to as relapses, flare-ups or exacerbations) of new symptoms or worsening of old ones may occur at any time, months or years apart. These episodes can vary in severity and length.

The role of treatment

MS is a life-long condition that presently can be treated but not cured. Appropriate therapy may be used to reduce the number and severity of clinical exacerbations, and to slow progression of disability. To get the most of your treatment with Rebif^®, it should be taken regularly, as prescribed by your doctor.
