What is Transverse Myelitis?
Transverse myelitis is a neurological condition that involves inflammation of both sides of a section of the spinal cord. This inflammation can disrupt the messages sent by nerves in the spinal cord, leading to symptoms such as pain, weakness, paralysis, or sensory issues. The condition can occur suddenly and may affect people of any age.
What Causes Transverse Myelitis?
Transverse myelitis can result from a variety of triggers, though sometimes the exact cause remains unknown. Possible causes include:
- Viral or bacterial infections – Respiratory or gastrointestinal infections can trigger an immune response.
- Autoimmune diseases – Conditions like lupus or multiple sclerosis may cause inflammation in the spinal cord.
- Post-vaccination reaction – Rarely, it can occur after immunizations.
- Neurological disorders – Including neuromyelitis optica or other demyelinating conditions.
- Paraneoplastic syndromes – Linked to certain cancers affecting the immune response.
What are the Symptoms of Transverse Myelitis?
Symptoms usually develop over hours to days and can vary depending on the part of the spinal cord involved. Common signs include:
- Sudden weakness in the arms or legs
- Pain in the lower back or extremities
- Numbness or tingling in the legs, torso, or arms
- Sensory loss or unusual sensations (burning, prickling)
- Bladder or bowel dysfunction, such as urgency or incontinence
- Muscle spasms or stiffness
Symptoms usually affect both sides of the body below the affected area of the spinal cord.
How is Transverse Myelitis Diagnosed?
A thorough evaluation helps identify the cause and rule out other conditions:
- Medical history and physical exam – To assess symptoms and neurological function.
- MRI scan – To visualize inflammation or lesions in the spinal cord.
- Lumbar puncture (spinal tap) – To check for infection or inflammation in the cerebrospinal fluid.
- Blood tests – To look for infections, autoimmune markers, or specific antibodies.
How is Transverse Myelitis Treated?
Treatment focuses on reducing inflammation, relieving symptoms, and promoting recovery:
- Corticosteroids – High-dose intravenous steroids are used to reduce spinal cord inflammation.
- Plasma exchange (plasmapheresis) – May be used if steroids are ineffective.
- Antiviral or antibiotic therapy – If an infection is identified.
- Pain management – Medications may help control nerve pain.
- Rehabilitation – Physical and occupational therapy can help restore mobility and strength.
- Supportive care – Bladder, bowel, and emotional support may be needed.
What is the Prognosis for Transverse Myelitis?
The outcome can vary. Some individuals recover fully, while others may have lingering symptoms. Recovery typically begins within weeks but can continue over several months or even years. Early treatment and rehabilitation improve the chances of a better outcome.
Can Transverse Myelitis Be Prevented?
In most cases, transverse myelitis cannot be prevented. However, managing risk factors may help:
- Treat infections promptly
- Control autoimmune disorders
- Stay up to date with recommended vaccinations
- Maintain overall health and immunity
When Should You See a Doctor?
Seek immediate medical attention if you or someone else experiences:
- Sudden weakness or numbness in the limbs
- Loss of bladder or bowel control
- Unexplained back pain with neurological symptoms
Early diagnosis and treatment are key to improving recovery and preventing long-term complications.
