Guillain-Barré syndrome (GBS) is a rare condition in which a person’s immune system attacks the peripheral nerves. The syndrome can affect the nerves that control muscle movement as well as those that transmit pain, temperature and touch sensations. This can result in muscle weakness and loss of sensation in the legs and/or arms.
It is a rare condition, and while it is more common in adults and in males, people of all ages can be affected.
The first symptoms of Guillain-Barré syndrome include weakness or tingling sensations. They usually start in the legs, and can spread to the arms and face. Guillain-Barré syndrome is often preceded by an infection. This could be a bacterial or viral infection.
