Primary progressive MS is characterised by worsening neurologic function or the constant accumulation of disability right from the onset of the disease, without periods of relapses or remissions. Approximately 10 to 15% of people with MS are diagnosed with PPMS.
Our MS in a Minute videos were created to provide fast and factual definitions of commonly used terms in MS.
