What causes multiple sclerosis (MS)?
No one knows what causes MS but we do know that the condition damages the myelin sheath, the material that surrounds and protects your nerve cells. This damage slows down or blocks messages between your brain and your body, leading to MS symptoms we’ll outline later.
Scientists have learned a great deal about MS in recent years but still its exact cause is unknown. Many researchers believe MS to be an autoimmune disease, one in which the body, through its immune system, launches a defensive attack against its own tissues. Increasing scientific evidence also suggests that genetics may play a role in determining a person's susceptibility to MS.
What we do know is this. MS is a relatively unpredictable disease of the central nervous system, and can range from relatively benign to somewhat disabling to devastating as communication between the brain and other parts of the body is disrupted. Usually, the disease is mild, but some people lose the ability to write, speak or walk.
Multiple sclerosis occurs when nerve cells become progressively damaged. During a severe case of MS, slurred speech, imbalance or muscle spasms can occur. But how can you be sure that you are experiencing multiple sclerosis? Learn to identify the symptoms of MS by reading the about early MS symptoms here.
