Multiple Sclerosis is a chronic central nervous system disorder that affects the brain, the spinal cord and the optic nerves. Multiple sclerosis is an auto-immune disorder in which the immune system attacks the protective myelin sheath of the nerves, causing nerve damage. The signs and symptoms of the condition vary widely, depending 0n the nerves affected and the extent of damage. With time, the disease can cause permanent loss of function in the affected nerves. With treatment, the patient’s symptoms and the pace of nerve degeneration can be managed and controlled.
