Primary Progressive MS is best described by which characteristic?

Explanation:
Primary Progressive MS is defined by a steady progression of disability from the onset, with no distinct relapses and remissions. This continuous worsening distinguishes it from relapsing-remitting MS, where episodes of new symptoms occur (relapses) followed by recovery (remission). The prevalence of PPMS is not around half of all cases; it represents a minority of MS, and MRI activity can vary—it’s possible to see active lesions or not, but progression from the start remains the defining feature.
