Progressive MS

Progressive MS is characterized by a continuous worsening of symptoms, independant of relapes. Progressive MS can be divided into two categories:

• Primary progressive MS occurs when the disease is progressive from the beginning. This affects about 15% of people with MS.
• Secondary progressive MS (SPMS) is characterized by a steady worsening of symptoms. Relapsing-remitting MS can progress insidiously over time and develop into SPMS.

How does multiple sclerosis progress?

• Relapsing-remitting MS can progress silently into secondary progressive MS (SPMS). 
• Key characteristic: slow deterioration of symptoms regardless of relapses. 
• SPMS still affects a significant proportion of patients. However, thanks to early detection and modern therapies, the onset of a SPMS can be delayed.

To determine if your MS is progressing, look for a worsening or new onset of the following symptoms.
