Primary progressive multiple sclerosis is a clinical phenotype of multiple sclerosis, a chronic immune-mediated neurodegenerative disorder affecting the central nervous system Accounting for approximately 10% to 15% of multiple sclerosis cases, it typically presents in adults during their 40s or 50s and affects males and females with roughly equal frequency Unlike relapsing disease courses, it is clinically characterized from disease onset by insidious, steadily worsening neurological disability...

Accounting for approximately 10% to 15% of multiple sclerosis cases, it typically presents in adults during their 40s or 50s and affects males and females with roughly equal frequency

Unlike relapsing disease courses, it is clinically characterized from disease onset by insidious, steadily worsening neurological disability without distinct relapses or remissions, frequently manifesting as progressive ambulatory impairment and spastic paraparesis

Unlike relapsing disease courses, it is clinically characterized from disease onset by insidious, steadily worsening neurological disability without distinct relapses or remissions, frequently manifesting as progressive ambulatory impairment and spastic paraparesis Pathophysiologically, the condition is driven predominantly by persistent compartmentalized inflammation, diffuse axonal injury, chronic demyelination, and early spinal cord and cortical neurodegeneration rather than acute multifocal ...

Pathophysiologically, the condition is driven predominantly by persistent compartmentalized inflammation, diffuse axonal injury, chronic demyelination, and early spinal cord and cortical neurodegeneration rather than acute multifocal inflammatory lesions
