Definition
By Mayo Clinic staffMultiple sclerosis (MS) is a potentially debilitating disease in which your body's immune system eats away at the protective sheath that covers your nerves. This interferes with the communication between your brain and the rest of your body. Ultimately, this may result in deterioration of the nerves themselves, a process that's not reversible.
Symptoms vary widely, depending on the amount of damage and which nerves are affected. People with severe cases of multiple sclerosis may lose the ability to walk or speak. Multiple sclerosis can be difficult to diagnose early in the course of the disease because symptoms often come and go — sometimes disappearing for months.
There's no cure for multiple sclerosis. However treatments can help treat attacks, modify the course of the disease and treat symptoms.
