	Recovery from TM varies among individuals and also depends on the underlying cause. Some patients start to recover between weeks 2 and 12 after onset and may continue to improve for up to two years.

'''Transverse myelitis''' is an inflammatory disorder affecting the spinal cord, resulting in varying degrees of muscle weakness, sensory disturbances, and autonomic dysfunction. The condition can be caused by various factors, including infections, autoimmune diseases, vaccinations, and spinal cord injuries.
[[File:Transverse Myelitis.PNG|thumb|Transverse Myelitis]]
==Signs and symptoms==
The symptoms of transverse myelitis can vary greatly between individuals and may develop rapidly over hours to days or more gradually over weeks. Symptoms include:
[[File:Transverse myelitis MRI.jpg|thumb|Transverse myelitis MRI]]
* Muscle weakness or paralysis
* Numbness or tingling
* Pain, often in the back or extremities
* Bowel and bladder dysfunction
* Muscle spasms
* Sensitivity to touch or temperature
==Causes==
The exact cause of transverse myelitis is often unknown, but potential causes include:

* Infections: Bacterial, viral, or parasitic infections can trigger an immune response leading to transverse myelitis.
* Autoimmune diseases: Conditions such as multiple sclerosis, neuromyelitis optica spectrum disorder, and systemic lupus erythematosus can cause transverse myelitis.
* Vaccinations: In rare cases, transverse myelitis may develop following vaccination.
* Vascular disorders: Disorders affecting blood vessels in the spinal cord may contribute to the development of transverse myelitis.
* Spinal cord injuries: Physical trauma to the spinal cord can cause localized inflammation and damage.
==Diagnosis==
The diagnosis of transverse myelitis involves several tests, including:

* [[Magnetic resonance imaging (MRI)]]: This imaging technique is used to visualize the spinal cord and identify areas of inflammation.
* [[Lumbar puncture]]: A sample of cerebrospinal fluid is collected to check for abnormalities, such as elevated protein levels or the presence of immune cells.
* Blood tests: These are performed to rule out other potential causes, such as infections or autoimmune diseases.
==Treatment==
Recovery from TM varies among individuals and also depends on the underlying cause. Some patients start to recover between weeks 2 and 12 after onset and may continue to improve for up to two years. However, other patients may never show signs of recovery. If treated early, some patients experience complete or near-complete recovery. Treatment options also vary according to the underlying cause.
