Multiple Sclerosis

Multiple Sclerosis is a chronic condition that affects the central nervous system, which includes the brain and spinal cord. It occurs when the body's immune system mistakenly attacks the protective covering called myelin around nerve fibers. This damage disrupts the normal flow of electrical signals, leading to a variety of symptoms such as weakness, vision problems, and difficulty with coordination and balance. The disease often causes episodes of symptoms that come and go, but over time it can lead to permanent nerve damage. People with this condition may experience challenges with daily activities due to these neurological impairments.

Multiple Sclerosis is a chronic, immune-mediated demyelinating disease of the central nervous system characterized by focal areas of inflammation, demyelination, and axonal injury. The pathogenesis involves an aberrant autoimmune response targeting myelin sheaths and oligodendrocytes, leading to impaired nerve conduction. It typically presents with relapsing-remitting neurological deficits affecting sensory, motor, and autonomic pathways. The disease is marked by dissemination in time and space of lesions within the brain and spinal cord. Major clinical significance includes progressive neurological disability and potential cognitive impairment. Genetic susceptibility and environmental factors contribute to disease risk.
