Guillain-Barré Syndrome: Causes, Signs & Management
Guillain-Barré syndrome (GBS) is a rare neurological disorder in which the immune system mistakenly attacks the peripheral nerves. It often develops after an infection and can cause rapidly progressive weakness; severe cases can affect breathing, swallowing, and heart rate or blood pressure.
🔹 Core clinical features
➟ Rapidly progressive muscle weakness
➟ Weakness often begins in the legs and moves upward
➟ Reduced or absent deep tendon reflexes
➟ Symptoms usually develop over days to a few weeks
🔹 Common signs
➟ Tingling or pins-and-needles in the feet and hands
➟ Symmetrical weakness, usually starting in the legs
➟ Difficulty walking or climbing stairs
➟ Facial weakness or difficulty swallowing
➟ Back or limb pain may occur
➟ Severe cases can cause breathing difficulty
🔹 Common causes / triggers
➟ Often occurs after a respiratory or gastrointestinal infection
➟ Campylobacter jejuni infection is a well-known trigger
➟ Influenza, COVID-19, cytomegalovirus, and other infections can precede GBS
➟ Rarely, GBS may occur after surgery or vaccination
➟ In many cases, the exact trigger is not identified
🔹 Diagnosis
➟ Neurological examination for weakness and reduced reflexes
➟ Nerve conduction studies / electromyography (EMG)
➟ Lumbar puncture may show high CSF protein with relatively few white blood cells
➟ Breathing function should be monitored closely
🔹 Core management
➟ Most suspected cases require urgent hospital assessment
➟ IV immunoglobulin (IVIG) is a standard treatment
➟ Plasma exchange (plasmapheresis) is an effective alternative
➟ Monitor breathing, heart rhythm, blood pressure, and swallowing
➟ Physiotherapy and rehabilitation help restore strength and mobility
🔹 Possible complications
➟ Respiratory failure requiring mechanical ventilation
➟ Abnormal heart rate or unstable blood pressure
➟ Difficulty swallowing and aspiration
➟ Blood clots and pressure injuries from immobility
➟ Persistent weakness, numbness, pain, or fatigue
🔹 What not to do
➟ Don't delay assessment for rapidly increasing weakness
➟ Don't attempt strenuous exercise during the acute phase
➟ Don't assume progressive leg weakness is simple fatigue
➟ Corticosteroids alone are not an effective treatment for GBS
🔹 Emergency / referral warning
➟ Weakness rapidly spreading from the legs upward
➟ New difficulty breathing or swallowing
➟ Inability to stand or walk
➟ Facial weakness with rapidly progressing limb weakness
➟ These symptoms require immediate emergency medical assessment
🔹 High-Yield Points
➟ Classic pattern = ascending symmetrical weakness + reduced/absent reflexes
➟ GBS frequently follows an infection
➟ Campylobacter jejuni is a classic trigger
➟ IVIG and plasma exchange are the main disease-modifying treatments
➟ Respiratory and autonomic complications make GBS a potential medical emergency
