Transverse Myelitis
Background
Transverse Myelitis (TM) is a rare neurological disorder of the central nervous system caused by inflammation across the spinal cord. TM can affect adults and children of both sexes and all ethnic groups. It is thought to have an incidence of between 1 and 5 in 1,000,000.
Onset of TM is usually sudden over a day or two but in some people it can develop over a longer period. Swelling, caused by inflammation, blocks messages to the brain relating to touch, pain and temperature, resulting in numbness or altered feeling. Messages from the brain also cannot get down the cord causing weakness or paralysis in the limbs, usually the legs. Control of bladder and bowel can also be affected by the inflammation in the cord. Although the effects disappear as the swelling reduces, damage can be more long term.
