Understanding Guillain-Barré Syndrome: Causes, Symptoms, and Treatment

Guillain-Barre (gee-YAH-buh-RAY) syndrome is a rare disorder in which your body's immune system attacks your nerves. Weakness and tingling in your hands and feet are usually the first symptoms.

These sensations can quickly spread, eventually paralyzing your whole body. In its most severe form Guillain-Barre syndrome is a medical emergency. Most people with the condition must be hospitalized to receive treatment.

The exact cause of Guillain-Barre syndrome is unknown. But two-thirds of patients report symptoms of an infection in the six weeks preceding. These include a COVID-19, respiratory or a gastrointestinal infection or Zika virus.

There's no known cure for Guillain-Barre syndrome, but several treatments can ease symptoms and reduce the duration of the illness. Although most people recover completely from Guillain-Barre syndrome, some severe cases can be fatal. While recovery may take up to several years, most people are able to walk again six months after symptoms first started. Some people may have lasting effects from it, such as weakness, numbness or fatigue.

Guillain Barre Syndrome Symptoms

Guillain-Barre syndrome often begins with tingling and weakness starting in your feet and legs and spreading to your upper body and arms. Some people notice the first symptoms in the arms or face. As Guillain-Barre syndrome progresses, muscle weakness can turn into paralysis.

Signs and symptoms of Guillain-Barre syndrome may include:

• A pins and needles sensation in your fingers, toes, ankles or wrists
• Weakness in your legs that spreads to your upper body
• Unsteady walking or inability to walk or climb stairs
• Difficulty with facial movements, including speaking, chewing or swallowing
• Double vision or inability to move the eyes
• Severe pain that may feel achy, shooting or cramplike and may be worse at night
• Difficulty with bladder control or bowel function
• Rapid heart rate
• Low or high blood pressure
• Difficulty breathing

People with Guillain-Barre syndrome usually experience their most significant weakness within two weeks after symptoms begin.

Types

Guillain-Barre syndrome has several forms. The main types are:

• Acute inflammatory demyelinating polyradiculoneuropathy (AIDP), the most common form in North America and Europe. The most common sign of AIDP is muscle weakness that starts in the lower part of your body and spreads upward.
• Miller Fisher syndrome (MFS), in which paralysis starts in the eyes. MFS is also associated with unsteady gait. MFS is less common in the U.S. but more common in Asia.
• Acute motor axonal neuropathy (AMAN) and acute motor-sensory axonal neuropathy (AMSAN) are less common in the U.S. But AMAN and AMSAN are more frequent in China, Japan and Mexico.
