Multiple sclerosis (MS) and transverse myelitis are conditions that affect the central nervous system (CNS). However, MS affects nerves in the brain and spinal cord, while transverse myelitis only affects the spinal cord.
Both MS and transverse myelitis damage the CNS, in particular the myelin, which is the protective covering of nerve cells. There are some similarities in the symptoms of both conditions.
However, transverse myelitis affects only the spinal cord, while MS can affect multiple areas within the brain and spinal cord. As such, although some symptoms may overlap, the two conditions can present differently.
Read on to learn more about the differences and similarities between MS and transverse myelitis.
It occurs when the immune system
The immune attack causes inflammation, which erodes the myelin sheath and may damage the underlying nerves. This process can sometimes leave a scar.
The term multiple sclerosis means “scar tissue in multiple areas.” The loss of myelin may prevent the body from carrying out certain functions.
Myelin insulates the nerves so that they can efficiently send electrical impulses from the brain around the body. These impulses control almost all bodily functions, from breathing to muscle contraction.
The brain also receives sensory information via the spinal cord from nerves throughout the body. This sensory information helps the brain detect sensations such as pain or temperature.
The areas of the body transverse myelitis affects
MS is an autoimmune disease where immune cells
Because MS has similar symptoms to transverse myelitis, people can mistake the two conditions for each other.
Both may cause the following:
Vision problems are a common and often an early symptom of MS.
Potential causes of MS
- Immune response to infection: If viruses share a similar molecular structure with the brain or nerves, they can trick the immune system into attacking the nervous system. This process is called molecular mimicry.
- Genetics: While people do not necessarily inherit MS, some genes can increase a person’s risk of developing it.
- Epstein-Barr virus (EBV): Around
95%of the population contracts EBV. It is not necessarily the virus that can increase MS risk but a person’s immune response to EBV.
Possible causes of transverse myelitis
- Autoimmune disorders: These include MS and aquaporin-4 autoantibody-associated neuromyelitis optica.
- Immune system changes during cancer: This mainly occurs in cancers that affect the nervous system.
- Post-infectious or post-vaccine autoimmune phenomenon: This is when the body attacks parts of the nervous system in response to an infection or, rarely, a vaccine.
Some environmental risk factors can increase MS and transverse myelitis risk.
- MRI imaging to detect lesions in the brain and spinal cord
- lumbar puncture with spinal fluid analysis
- evoked potential tests
- CT scans
- blood tests
However, it is important to note that a healthcare professional can only make a diagnosis of MS if a person has more than one episode.
Otherwise, a doctor may instead diagnose clinically isolated demyelination until another episode occurs. Typically, a doctor will diagnose transverse myelitis during an individual episode.
While several treatments aim to stop the progression of MS and transverse myelitis, there is currently no cure.
Treatments for MS
- intravenous (IV) corticosteroid drugs for treating exacerbations
- plasma exchange therapy for treating exacerbations
- a range of disease-modifying treatments, including beta interferon and glatiramer, to prevent exacerbations
A healthcare professional will treat transverse myelitis as a single event, distinguishing it from MS treatment. Treatments
- IV corticosteroid drugs
- plasma exchange therapy
- antibody therapy called intravenous immunoglobulin
A healthcare professional may also recommend pain medications and muscle relaxants for treating pain or muscle spasms that may occur with MS or transverse myelitis.

Symptoms of MS and transverse myelitis can be similar, as both conditions affect the central nervous system.
Doctors use various tools to diagnose them, such as imaging studies and spinal fluid analyses. The main difference is that MS causes damage to nerves in the brain and spinal cord, while transverse myelitis only affects the spinal cord.
There is currently no cure for MS and transverse myelitis. However, several treatments aim to stop symptom progression and prevent further damage to the central nervous system.
