Types of Multiple Sclerosis and Their Characteristics
Multiple sclerosis manifests in several distinct forms, each with unique characteristics and progression patterns. Relapsing-remitting MS (RRMS) is the most common form, affecting approximately 85% of people initially diagnosed with MS. This type is characterized by clearly defined relapses followed by periods of partial or complete recovery.
Secondary progressive MS (SPMS) typically develops from RRMS, where the disease begins to progress more steadily with or without occasional relapses. Primary progressive MS (PPMS) accounts for about 10-15% of cases and is characterized by gradually worsening neurologic function from the onset, without early relapses or remissions.
Progressive-relapsing MS (PRMS) is the least common form, featuring steady progression from the beginning with acute relapses along the way. Understanding these different types helps healthcare providers develop personalized treatment strategies and helps patients better understand their prognosis and treatment options.
