Multiple Sclerosis is thought to be an autoimmune disease that effects the central nervous system(CNS). It effects the brain, spinal cord, amd the optic nerves. Surrounding and protecting the nerve fibres is some fatty tissue called myelin, which helps nerve fibres conduct electrical impulses.
In ms, Myelin is lost in mutiple areas, leaving scar tissue. This is usually damaged and are known as plaques or lesions, sometimes damaged or broken.
Myelin not only protects nerve fibres, when the myelin or the nerve fyber becomes destroyed or damaged, the ability of the nerves to conduct electrical impulses to and from the brain is disrupted, and then this produces the symptoms of ms
