Video - Multiple sclerosis

Multiple sclerosis is a progressive, demyelinating disease on the central nervous system, characterized by the destruction of myelin, the protective sheath surrounding nerve cells, as well as inflammation and scarring of nerve fibers.

Damage to these nerves disrupts the ability of parts of the nervous system to transmit impulses, resulting in a wide range of signs and symptoms, including physical, mental, and sometimes psychiatric problems. Symptoms vary widely, but they may include muscle weakness, fatigue, vision problems, balance and coordination problems, and problems with memory and thinking.
