What Are the Five Stages of Multiple Sclerosis (MS)?
Learn about the five stages of Multiple Sclerosis, including CIS, RRMS, SPMS, PPMS, and PRMS, and their key characteristics.
Video transcript
The five stages of Multiple Sclerosis (MS) are: 1. Clinically Isolated Syndrome (CIS) - first episode of neurological symptoms. 2. Relapsing-Remitting MS (RRMS) - periods of new symptoms or relapses. 3. Secondary Progressive MS (SPMS) - follows RRMS, with a progressive worsening of symptoms. 4. Primary Progressive MS (PPMS) - progressive worsening of neurological function from onset. 5. Progressive-Relapsing MS (PRMS) - progressive form with clear relapses.
Questions and answers
What is Clinically Isolated Syndrome (CIS) in MS?
CIS is the first episode of neurological symptoms lasting at least 24 hours, which may or may not develop into Multiple Sclerosis.
How does Relapsing-Remitting MS differ from Progressive MS?
Relapsing-Remitting MS (RRMS) involves episodes of new or worsening symptoms followed by recovery periods, whereas Progressive MS shows continuous worsening without distinct relapses.
Can Multiple Sclerosis progress from one stage to another?
Yes, many patients with RRMS eventually enter Secondary Progressive MS, characterized by steady worsening of symptoms.
