Primary Progressive Multiple Sclerosis (PPMS) Epidemiology

Key Highlights

• Primary Progressive Multiple Sclerosis (PPMS), is a distinct form of Multiple Sclerosis, which is characterized by a gradual worsening of neurological function from the onset, without the typical relapses and remissions seen in other forms of multiple sclerosis.
• The progressive phase of multiple sclerosis (primary progressive and secondary progressive) is the result of long-lasting degenerative changes, which appear only when an age threshold is reached and progresses at similar rates.
• PPMS is the least common type of disease, diagnosed in about 10–15% of MS patients.
• As per Delveinsight, the total number of diagnosed prevalent cases of Primary Progressive Multiple Sclerosis in the US is ~120,000 in 2023.
• Women are more likely to develop PPMS than men. In the United States, the number of women cases of Primary Progressive Multiple Sclerosis are about 3 times more than the cases of men.
• Primary Progressive Multiple Sclerosis is more common in the age group of 45-54 years and approximate 40,000 cases were related to this age group in US during year 2023.

Primary Progressive Multiple Sclerosis (PPMS): Disease Understanding 

Primary Progressive Multiple Sclerosis (PPMS) Overview, and Diagnosis

Primary Progressive Multiple Sclerosis (PPMS) is a rare and challenging form of multiple sclerosis, accounting for about 10–15% of MS cases. Unlike relapsing forms, PPMS is characterized by a gradual, continuous decline in neurological function without periods of remission or relapses. Over time, individuals with PPMS experience accumulating disability, particularly affecting mobility. The disease progression is steady, leading to long-term impairment, making early diagnosis and effective management crucial for improving the patient's quality of life.

Diagnosing PPMS requires meeting specific criteria due to its unique progression pattern. The process includes a careful medical history, neurological exam, and tests like MRI, spinal fluid analysis, and blood tests to rule out other conditions. The primary diagnostic criteria are one year of continuous disease progression and the presence of two out of three key markers: typical brain lesions, multiple spinal cord lesions, or signs of immune activity in the spinal fluid (e.g., oligoclonal bands). Since PPMS progresses gradually, it can take 2–3 years longer to diagnose compared to other MS types, further complicating early intervention and treatment.

Although there is no cure for PPMS, various treatment approaches focus on managing symptoms and slowing disease progression. These include Disease-Modifying Therapies (DMTs) such as OCREVUS (ocrelizumab) and OCREVUS ZUNOVO (ocrelizumab and hyaluronidase-ocsq), as well as symptomatic management and lifestyle adjustments. Symptomatic management remains a cornerstone of care.
