What is Guillain-Barré syndrome in children?

Guillain-Barré syndrome (GBS) is a short-term but often life-threatening disorder that affects the nerves in the body. GBS can cause muscle weakness, pain, and short-term (temporary) paralysis of the facial, chest, and leg muscles. Paralyzed chest muscles can lead to breathing problems and death if not treated. Most children diagnosed with GBS recover fully with no complications. Recovery often starts within a few weeks after the symptoms begin.

What causes GBS in a child?

Researchers don’t know the exact cause of GBS. GBS may be an autoimmune disorder that causes the body's immune system to attack part of the nervous system. This can occur after a viral infection, surgery, or injury, or as a reaction to a vaccine. About 2 out of 3 people who develop symptoms of GBS do so a few days or weeks after diarrhea or a respiratory illness.

Which children are at risk for GBS?

GBS is rare, but any child can develop it.

What are the symptoms of GBS in a child?

Symptoms can occur a bit differently in each child. They can include:

  • Decreased feeling in fingers and toes
  • Pain in fingers and toes
  • Leg weakness
  • Leg pain that moves to the arms
  • Problems walking
  • Irritability
  • Breathing problems
  • Facial weakness
  • Vision changes

Your child may have muscle weakness for 1 to 2 weeks. This can last up to 1 to 2 months, with full recovery at least 1 to 2 years after diagnosis.

The symptoms of GBS can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.

How is GBS diagnosed in a child?

The healthcare provider will ask about your child’s symptoms and health history. He or she will give your child a physical exam. Your child may also have tests, such as:

  • Blood tests and urine tests. These are done to check for infections and other problems.
  • Lumbar puncture (spinal tap). This test uses a needle to help measure the pressure in the spinal canal and brain. The healthcare provider can also remove a small amount of cerebral spinal fluid (CSF) to send for testing. CSF is the fluid that surrounds your child's brain and spinal cord. The fluid sample can help show if your child has an infection or other problems.
  • Electromyogram (EMG). This test measures the electrical activity of a muscle or a group of muscles. An EMG can find abnormal electrical muscle activity caused by diseases and conditions that affect the nerves and muscles.
  • Pulmonary function test. This is a breathing test done by a respiratory therapist. It shows your child’s lung capacity and how strong his or her respiratory muscles are. This test is often used to decide if a child needs breathing support with a ventilator.

How is GBS treated in a child?

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.

There is no treatment to cure GBS. The key to managing GBS is finding it early. This condition will go away on its own, but can be life threatening. A child with GBS will need to be in a hospital intensive care unit (ICU) and closely watched by a healthcare team.

The goal of treatment is to prevent breathing problems and ease symptoms. Medicines are used to control pain and other problems. In severe cases, your child may need to be on a breathing machine (ventilator).

Your child may also need treatment to suppress the immune system or reduce inflammation. This may include:

  • Immunoglobulin therapy. This is treatment with a blood product that helps to decrease the immune system's attack on the nervous system.
  • Plasmapheresis. This is a procedure to remove the fluid part of the blood (plasma) and replace it with other fluids. Antibodies are also removed with the plasma. This may help reduce the symptoms of the disease. Plasmapheresis is a complex procedure that can be hard to do on young children. For this reason, immunoglobulin therapy is often done first.

Talk with your child’s healthcare providers about the risks, benefits, and possible side effects of all treatments.

During the course of the illness, your child may develop stiff muscles and contracted joints. He or she may need physical, occupational, or speech therapy during recovery. This is to help him or her regain muscle strength, and speech and swallowing skills.

The healthcare team will tell you how to best care for your child at home. Make sure your child gets enough rest and activity. Your child will also likely need regular visits with the healthcare provider after he or she gets home from the hospital.

What are the possible complications of GBS in a child?

Most children diagnosed with GBS recover fully with no complications. If GBS is not treated, paralysis of the chest muscles can lead to breathing problems and death. Recovery often starts within a few weeks after the onset of symptoms. Your child may have muscle weakness for 1 to 2 weeks. This can last up to 1 to 2 months, with full recovery at least 1 to 2 years after diagnosis.

When should I call my child’s healthcare provider?

Call the healthcare provider if your child has:

  • Symptoms that don’t get better, or get worse
  • New symptoms

Next steps

Tips to help you get the most from a visit to your child’s healthcare provider:

  • Know the reason for the visit and what you want to happen.
  • Before your visit, write down questions you want answered.
  • At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child.
  • Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are.
  • Ask if your child’s condition can be treated in other ways.
  • Know why a test or procedure is recommended and what the results could mean.
  • Know what to expect if your child does not take the medicine or have the test or procedure.
  • If your child has a follow-up appointment, write down the date, time, and purpose for that visit.
  • Know how you can contact your child’s provider after office hours. This is important if your child becomes ill and you have questions or need advice.
