What is Transverse Myelitis? How is it Treated?
Transverse myelitis is a rare but serious neurological disorder affecting both sides of the spinal cord. This condition occurs as a result of damage to myelin, the protective sheath surrounding nerve fibers in the spinal cord. This inflammation in the spinal cord interrupts the transmission of nerve signals throughout the body, causing pain, muscle weakness, paralysis, sensory problems, or bladder and bowel dysfunction.
In this article, we will take an in-depth look at what transverse myelitis is, what causes it, how it is diagnosed, and the treatment options available in modern medicine.
What are the symptoms of transverse myelitis?
Symptoms of transverse myelitis usually develop suddenly (within a few hours) or can progress over a period of a few days to weeks. Symptoms vary depending on which region of the spinal cord is affected. The most common symptoms include:
Pain: It is a sharp pain that usually starts suddenly in the lower back. This pain can radiate to the legs, arms, or torso.
Sensory Changes: Numbness, tingling, coldness, or burning sensations are common. Many patients describe a sensation as if a belt is being tightened around their torso.
Weakness in Legs and Arms: Patients may feel heaviness in their legs or drag their feet. Complete paralysis can develop in severe cases.
Bladder and Bowel Problems: Issues such as an increased urge to urinate, urinary incontinence, or constipation are frequently seen.
Causes of Transverse Myelitis
The exact cause of transverse myelitis may not always be determined (idiopathic). However, studies point to several main factors that can trigger this condition:
Immune System Disorders: The body’s own immune system mistakenly attacking spinal cord tissue (an autoimmune response).
Viral Infections: It can develop following viruses such as herpes simplex, chickenpox (zoster), HIV, Epstein-Barr, and influenza.
Bacterial Infections: Bacterial conditions such as Lyme disease, syphilis, or tuberculosis can be triggers, albeit rarely.
Multiple Sclerosis (MS): Transverse myelitis can sometimes appear as the first symptom of MS disease.
Neuromyelitis Optica (Devic’s Disease): A disease that affects both the spinal cord and the optic nerves.
How is it diagnosed?
An accurate diagnosis is critical to the success of treatment. A neurologist typically utilizes the following methods:
Magnetic Resonance Imaging (MRI): It is the gold standard to visualize the inflammation in the spinal cord and see other possible causes (tumor, hernia, etc.).
Lumbar Puncture (Spinal Tap): Used to measure the level of white blood cells or proteins in the cerebrospinal fluid (CSF).
Blood Tests: Performed to screen for infections or specific antibodies (such as NMO antibodies).
What are the treatment methods?
The main goal of treatment is to reduce inflammation and alleviate symptoms. The methods generally used are:
Intravenous Steroids: Administered intravenously in high doses to rapidly suppress inflammation.
Plasma Exchange (Plasmapheresis): Used to clear harmful antibodies from the blood in cases where steroids are insufficient.
Immunomodulatory Drugs: Used to regulate the immune system in recurrent cases.
Physical Therapy and Rehabilitation: It is the most critical part of the treatment to maintain muscle strength, increase flexibility, and regain mobility.
Recovery Rate and Quality of Life
The recovery process varies greatly from person to person. Some patients show complete recovery within the first few months, while others may have to live with permanent neurological damage. Early intervention generally ensures better results.
