What affect does MS have on the nervous system

AMS causes nervous system signals to be redirected so that messages reach unintended body parts.
BMS gradually destroys myelin sheaths in the CNS increasing the speed in which nerve impulses are conducted.
CMS gradually destroys myelin sheaths in the CNS impeding the conduction of nerve impulses.
