(HealthDay student loan calculator News) — Multiple sclerosis, a disease that strikes the central nervous system, occurs when the body’s own immune system attacks myelin — the sheath that surrounds nerves.

Symptoms companies of MS vary from mild to severe, and can include tingling or loss of feeling in some part of the body, fatigue, balance or coordination problems, blurred vision or slurred speech. People diagnosed with MS may experience one, a few, or many symptoms.

There is no cure, the National Multiple Sclerosis Society says, but a variety of drug, exercise and diet remedies can help treat the disease and control symptoms. Physical, occupational and speech therapy also can help people with MS live comfortably and independently, the society says.
