MS Diagnostics - The Clinical Perspective

This lecture provides a comprehensive clinical overview of Multiple Sclerosis (MS), bridging the gap between historical descriptions and modern neurology. It explores the biology of MS as an inflammatory and neurodegenerative process affecting both white and gray matter. The session details the different disease subtypes, including the emerging concept of "smoldering MS,” and highlights the shift toward early, high-efficacy treatment to prevent long-term disability.

Learning objectives

By the end of this lecture, students will be able to:

• Explain the biological hallmark of MS, including the roles of demyelination, axonal loss, and blood-brain barrier disruption.
• Identify the primary disease courses, distinguishing between Relapsing-Remitting (RRMS), Secondary Progressive (SPMS), and Primary Progressive (PPMS).
• Define "smoldering MS" and PIRA (Progression Independent of Relapse Activity) as critical markers for long-term neurodegeneration.
• Describe common clinical symptoms, such as optic neuritis, motor spasticity, and cognitive fatigue, and their impact on patient's quality of life.
• Evaluate the epidemiological risk factors, including the roles of Epstein-Barr virus (EBV), Vitamin D levels, and lifestyle choices like smoking and obesity.
• Analyze current treatment strategies, comparing immunomodulators, cell-traffic inhibitors, and high-efficacy B-cell depletion therapies.
