Definition & Meaning of "multiple sclerosis"

What is "multiple sclerosis"?

Multiple sclerosis (MS) is a condition where the body's immune system attacks the protective covering of nerves in the brain and spinal cord. This can damage the flow of information between the brain and the body, leading to symptoms such as fatigue, weakness, numbness or tingling, and problems with coordination and balance. The exact cause of MS is unknown, but it is believed to involve a combination of genetic and environmental factors. Treatment for MS focuses on managing symptoms, slowing the progress of the disease, and improving quality of life. This may involve medications, physical therapy, and lifestyle changes.
