About Transverse Myelitis
Transverse myelitis is an inflammation of the spinal cord, a major part of the central nervous system. The spinal cord carries nerve signals to and from the brain through nerves that extend from each side of the spinal cord and connect to nerves elsewhere in the body. The term myelitis refers to inflammation of the spinal cord; transverse refers to the pattern of changes in sensation—there is often a band-like sensation across the trunk of the body, with sensory changes below.
Causes of transverse myelitis include infections, immune system disorders, and other disorders that may damage or destroy myelin, the fatty white insulating substance that covers nerve cell fibers. Inflammation within the spinal cord interrupts communications between nerve fibers in the spinal cord and the rest of the body, affecting sensation and nerve signaling below the injury. Symptoms include pain, sensory problems, weakness in the legs and possibly the arms, and bladder and bowel problems. The symptoms may develop suddenly (over a period of hours) or over days or weeks.
