Although most people with transverse myelitis have at least partial recovery, it may take a year or more. Most recovery occurs within the first three months after the episode and strongly depends on the cause of transverse myelitis.
About one-third of people with transverse myelitis fall into one of three categories after an attack:
No or slight disability. These people experience only minimal lingering symptoms.
Moderate disability. These people are mobile, but may have difficulty walking, numbness or tingling, and bladder and bowel problems.
Severe disability. Some people may permanently need a wheelchair and require ongoing assistance with daily care and activities.
It's difficult to predict the course of transverse myelitis. The prognosis and responsiveness to treatment is strongly determined by the cause of the syndrome and to some extent by how early treatment is administered. Generally, people who experience a rapid onset of severe signs and symptoms and those who have a positive test for a particular antibody have a worse prognosis than do those with a relatively slower onset, milder symptoms and negative antibody test.
