[[Demyelination]] is a process characterized by the gradual loss of the myelin sheath enveloping nerve fibers. When myelin deteriorates, signal conduction along nerves can be significantly impaired or lost, and the nerve eventually withers. Demyelination may affect both central and peripheral nervous systems, contributing to various neurological disorders such as [[multiple sclerosis]], [[Guillain–Barré syndrome|Guillain-Barré syndrome]], and [[chronic inflammatory demyelinating polyneuropathy]]. Although demyelination is often caused by an [[Autoimmunity|autoimmune]] reaction, it may also be caused by viral infections, metabolic disorders, trauma, and some medications.
