Multiple sclerosis is a disease that may affect nerves of the Brain and the Spinal cord.Multiple sclerosis affects transmission of electric signals to nerve cells.It is the most common cause of chronic neorological disability in young adults.It is not contagious.In MS the nerves of the CNS (brain and spinal cord )degenerate.(Myelin ,which provides a covering or insulation for nerves,improves the conduction of impulses along the nerves and also is maintaining the health of nerves.).In MS, Inflammation causes the myelin to eventually disappear.Thus, the electrical impulses that travel along the nerve deaccelerate i.e. become slower. The nerves are damaged.As more and more nerves are affected ,patient experiences a progressive interference with functions which are controlled by nervous system such as VISION,SPEECH,WALKING,WRITING and MEMORY.
