Guillain-Barré (pronounced Ghee-lan Bar-ray) syndrome is a rare but serious condition of the peripheral nervous system. It is named after two of three French doctors who first described the condition in 1916, Georges Charles Guillain and Jean-Alexander Barré.

The peripheral nervous system

The peripheral nervous system is the network of nerves that control the body’s senses and movements. In Guillain-Barré syndrome, the immune system (the body’s natural defence against infection and illness) attacks these nerves, causing them to become inflamed.

Inflammation of the peripheral nerves leads to a tingly, numbing sensation in the arms and legs. This can eventually result in a short-term loss of feeling and movement (temporary paralysis). See Guillain-Barré syndrome – symptoms for more information.

Link with infection

The exact cause of Guillain-Barré syndrome is unclear. There is no way of identifying who is most at risk.

However, in most cases of Guillain-Barré syndrome, the person affected had a viral or bacterial infection a few weeks before getting the condition. It is likely that the infection causes the immune system to attack the body’s nerves.

How common is Guillain-Barré syndrome?

Guillain-Barré syndrome affects 50-100 people in Ireland each year. It is slightly more common in men than women. It can affect people of any age, including children.

Outlook

Most people (about 8 out of 10) with Guillain-Barré syndrome make a full recovery within a few weeks or months, and do not have any further problems. Some people may take longer to recover, and there is a possibility of permanent nerve damage.
