Demyelination

Demyelination is a condition where the protective covering called myelin around nerve fibers is damaged or lost. Myelin acts like insulation for electrical signals traveling through nerves, ensuring messages reach the brain and body efficiently. When it’s damaged, nerve signals slow down or become disrupted, leading to symptoms like weakness, numbness, loss of coordination, or problems with vision and speech. Conditions such as multiple sclerosis are examples of demyelination diseases. The severity and symptoms depend on how much myelin is damaged and which nerves are affected.
