Detailed explanation-1: -Multiple sclerosis (MS) is the most common demyelinating and an autoimmune disease of the central nervous system characterized by immune-mediated myelin and axonal damage, and chronic axonal loss attributable to the absence of myelin sheaths.
Detailed explanation-2: -In MS, the immune system launches an inflammatory attack in the central nervous system. This inflammation leads to demyelination-the deterioration and loss of the myelin sheath-and causes damage to axons.
Detailed explanation-3: -What happens to myelin in MS? In MS, immune cells enter the brain and spinal cord and attack both the myelin and the cells that make it. When myelin becomes damaged, messages find it harder to get through – or can’t get through at all. That’s what causes the symptoms of MS.
Detailed explanation-4: -MS is caused by damage to the myelin sheath. This sheath is the protective covering that surrounds nerve cells. When this nerve covering is damaged, nerve signals slow or stop. The nerve damage is caused by inflammation.
