Multiple sclerosis (MS) is a condition that impacts the body’s central nervous system, which is made up of the brain and the spinal cord. For reasons currently unknown, when a person has MS, their immune system attacks the protective covering around their nerves (known as the myelin) and causes communication issues between the brain and the rest of the body. Depending on the severity of the condition, MS can cause a number of symptoms including vision problems, fatigue, dizziness, numbness, tingling, weakness in limbs, problems with bowel and bladder functions, and/or paralysis. These symptoms may be temporary or permanent.
