Approximately what percentage of MS patients are diagnosed with Primary Progressive MS (PPMS)?

Primary Progressive Multiple Sclerosis (PPMS) is characterized by a gradual worsening of neurologic function from the onset of symptoms, rather than the relapses and remissions seen in other forms of MS, such as relapsing-remitting MS. It typically accounts for a smaller subset of the overall MS patient population.

Research indicates that approximately 10% of individuals diagnosed with MS have PPMS, making this statistic significant in understanding the different clinical profiles of MS. Knowing this percentage is vital for both clinicians and patients, as it helps guide treatment decisions, establish prognosis, and shape support resources tailored to the progressive nature of this form of the disease.

While the other percentages provided may seem plausible, they do not accurately reflect the reported prevalence of PPMS in the MS community.
