Guide To The Types Of Myelitis

Acute Flaccid Myelitis

Acute flaccid myelitis is the type that affects the gray matter inside an individual's spinal cord. Many cases are caused by a viral infection. Examples include West Nile virus, enteroviruses, adenovirus, and poliovirus. Classic symptoms of this condition include loss of muscle tone, sudden leg or arm weakness, and absent or decreased reflexes.

Sometimes the nerves controlling an individual's neck and head can become inflamed as well. This results in eyelid drooping, speaking difficulties, facial weakness, problems swallowing, and difficulty moving the eyes. It can be difficult to pinpoint acute flaccid myelitis as the cause of associated symptoms. This is because the spinal fluid of affected individuals typically does not contain any causative pathogens. Diagnosis has to be made based on a physical examination, evaluation of the nervous system, and diagnostic imaging of the patient's spinal cord. Treatment usually involves occupational or physical therapy.
