Multiple sclerosis is a neurological disease that includes demyelination as one of its symptoms and associated conditions.  The demyelination process is similar to other neurological diseases, but the demyelination of brain nerves occurs more often in multiple sclerosis.  This is because the demyelination in multiple sclerosis occurs in the central nervous system, affecting nerves that send signals to the brain.

Demyelination occurs when the myelin sheath that surrounds and protects nerves gets damaged.  This occurs in many different neurological diseases, including multiple sclerosis.  The onset can come after an infection, such as post viral demyelination, exposure to certain chemicals, or for unknown reasons.  It can cause a variety of symptoms, from loss of feeling in the extremities and the face, muscle weakness, tingling or stinging sensations, loss of balance, fatigue, vision problems, cognitive problems, and even incontinence issues.
