Acute Flaccid Myelitis Signs and Symptoms

Acute Flaccid Myelitis Signs and Symptoms

How is acute flaccid myelitis diagnosed?

Clinicians diagnose AFM by taking a thorough medical history, doing a physical exam, and performing an MRI to review pictures of the spinal cord. Currently, there is no specific treatment for AFM, but clinicians may recommend different interventions based on each patient.

Does acute flaccid myelitis go away?

There is no known cure for AFM. Children are typically treated with high-dose steroids, which appear to help reduce the inflammation associated with the infection that has produced AFM.

How long does acute flaccid myelitis last?

These typically last 2 to 5 days, then go away. A much smaller number of children who get the virus have more serious symptoms like: A pins-and-needles feeling in their legs.

How is flaccid myelitis treated?

Currently, there is no specific treatment for acute flaccid myelitis. Treatment is aimed at managing symptoms. A doctor who specializes in treating brain and spinal cord illnesses (neurologist) might recommend physical or occupational therapy to help with arm or leg weakness.

How is AFM spread?

How is AFM spread? AFM is not spread from person to person. The viruses that are believed to cause AFM may be contagious from one person to another or may be spread by a mosquito or other vector depending on which virus causes the AFM.

What causes flaccid?

This abnormal condition may be caused by disease or by trauma affecting the nerves associated with the involved muscles. For example, if the somatic nerves to a skeletal muscle are severed, then the muscle will exhibit flaccid paralysis.

What is the difference between transverse myelitis and acute flaccid myelitis?

Before being described in 2014, AFM might have been diagnosed as a type of transverse myelitis. However, one difference between AFM and transverse myelitis has been found by magnetic resonance imaging (MRI) scans. The gray matter of the spinal cord is inflamed in people with AFM.

How do you prevent AFM?

AFM can be caused by viruses, including enteroviruses.

You can lower the risk of getting a virus by:
  1. Washing your hands often with soap and water for at least 20 seconds.
  2. Avoiding touching your face with unwashed hands.
  3. Avoiding close contact with people who are sick.

Is paralysis from AFM permanent?

Overview. Acute flaccid myelitis (AFM) is an uncommon, but life-threatening neurologic condition that affects mostly children and can lead to permanent paralysis.

What ages are affected by acute flaccid myelitis?

Most cases are in children, particularly in younger kids. The average age is around 5 years, though AFM has also occurred in older children and adults.

What are the symptoms of acute flaccid paralysis?

Symptoms
  • Sudden muscle weakness in the arms or legs.
  • Neck weakness.
  • Some other symptoms that patients may have include drooping eyelids or a facial droop, and difficulty swallowing or slurred speech.

Why does flaccid paralysis occur?

A common cause of flaccid paralysis is anterior spinal artery syndrome, in which the anterior spinal artery is blocked. Blockage can be caused by spinal cord trauma, cancer, arterial disease, or thrombosis.

What is considered flaccid?

Flaccid. This is the default state of the penis when you’re not sexually aroused. The penis is soft and hanging loosely from your groin area.

Is AFM sudden?

Acute flaccid myelitis (AFM) is a rare condition that affects the spinal cord. It comes on suddenly and makes muscles weak and floppy.

Has anyone recovered from AFM?

AFM can be a very difficult disease to diagnose, and unfortunately, we still don’t have a really good treatment to offer, says Evan’s pediatric neurologist, Neil Friedman, MBChB. Evan was very fortunate to have made a complete recovery; it was quite remarkable. Many children do not.

How is AFM different from polio?

Poliomyelitis caused by poliovirus no longer occurs in the United States. In 2014, the term AFM was adopted to describe poliomyelitis without a known cause and not caused by poliovirus. We now have stronger evidence that points to AFM being caused by non-polio enteroviruses, such as EV-D68 and EV-A71.

Is AFM a polio?

Acute flaccid myelitis (AFM) is a polio-like illness that affects the nerve cells (motor neurons) in the gray matter of the spinal cord. It is thought to be due to a viral infection. Children with AFM have acute (rapid) onset of flaccid (floppy) paralysis, usually in an arm or leg.
