by Multiple sclerosis (MS) is an unpredictable, often disabling disease of the central nervous system which is composed of the brain and spinal cord. The disease attacks the myelin which is a protective covering wrapped around the nerves of the central nervous system.
Symptoms of MS are unpredictable and vary greatly from person to person and from time to time in the same person.
MS attacks the protective covering — myelin — of the brain and spinal cord, causing inflammation and often damaging the myelin in patches. When this happens, the usual flow of nerve impulses along nerve fibres (axons) is interrupted or distorted. The result may be the wide variety of MS symptoms, depending upon what part or parts of the central nervous system are affected.
