Multiple sclerosis is a chronic autoimmune disorder that affects the central nervous system, causing episodes of neurologic dysfunction and often gradual disease progression. The immune system primarily targets myelin, the protective covering of nerve fibers, leading to inflammation and damage, and secondary neurodegeneration is a major cause of long-term disability. Common symptoms include vision problems, sensory disturbances, muscle weakness, balance difficulties, and bladder dysfunction. Important advances in treatment have improved outcomes in patients with relapsing forms of multiple sclerosis, particularly through highly effective immune-modifying therapies such as CD20-targeting monoclonal antibodies. However, treatment options for progressive forms remain limited, which highlights the need for therapies that can prevent progression and promote myelin repair. Comprehensive symptom management and lifestyle support are also essential to maintaining quality of life and reducing disability.
