Explanation:

Multiple slerosis is a autoimmune disease in which a person's immune system responds against its own Central  Nervous System (CNS). The immune response destroys the myelin sheath of the nerves.

As a result, the transmission of nerve impulse is disrupted. Damage to the nervous tissue is the cause of many neurological symptoms like speaking difficulty, loss of control on voluntary muscle etc. As a whole in multiple sclerosis the patient's brain loses control on his body.
