What is the cause of multiple sclerosis?

ANSWER

Doctors think multiple sclerosis -- no matter which type you have -- is a condition that happens when the body attacks itself, called an autoimmune disease. The immune system damages the protective coating around the nerves (called myelin) of the brain and spinal cord. This causes inflammation.
