Primary Progressive Multiple Sclerosis-A Key to Understanding and Managing Disease Progression.

Area of Science:

• Neuroimmunology
• Neurology
• Clinical Neuroscience

Background:

• Primary progressive multiple sclerosis (PPMS) is the least common form of multiple sclerosis (MS).
• PPMS presents unique clinical symptoms and a poor prognosis, often requiring extensive diagnostic workups.
• Despite advances, diagnosing and managing PPMS remains challenging, hindering effective treatment strategies.

Purpose of the Study:

• To review current evidence on PPMS, covering its background, clinical features, and diagnostic markers.
• To explore underlying mechanisms of central nervous system (CNS) damage in PPMS.
• To summarize therapeutic opportunities, including approved treatments and future research directions.

Main Methods:

• Comprehensive literature review of PPMS research.
• Analysis of studies investigating CNS damage processes in PPMS.
• Synthesis of information on biomarkers and therapeutic interventions for PPMS.

Main Results:

• PPMS involves chronic immune-mediated inflammation, neurodegeneration, and impaired remyelination.
• Potential clinical, biochemical, and radiological biomarkers are identified for monitoring and predicting PPMS progression.
• Current therapeutic options, ongoing trials, and future research avenues are summarized.

Conclusions:

• Understanding PPMS mechanisms can illuminate MS progression and inform clinical practice.
• Biomarkers are crucial for assessing outcomes and guiding personalized treatment in PPMS.
• Further research into PPMS may lead to novel therapeutic targets for managing disease progression.
