CausesThe exact cause of Guillain-Barré syndrome is unknown. However in about 70% of people, a recent infection or surgery triggers an autoimmune response. This autoimmune response attacks the peripheral nerves, leading to weakness and a loss of sensation.
Risk FactorsGuillain-Barré syndrome is more common in men, and in the those aged 15-35 years and 60-75 years old. Other factors that increase your chance of Guillain-Barré syndrome may include:
- Recent gastrointestinal or respiratory infection by viruses or bacteria
- Recent vaccination—especially influenza and meningococcal
- The swine flu vaccine given from 1976-1977 was linked to excess cases of Guillain-Barré syndrome. (Since then, influenza virus vaccines have been associated with only a marginally increased risk of Guillain-Barré syndrome.)
- Recent surgery
- History of lymphoma , systemic lupus erythematosus , or HIV infection
