For Patients & General Readers
Guillain-Barré Syndrome is a condition where your body's immune system mistakenly attacks your nerves. This can cause sudden weakness and tingling in your arms and legs, which can spread and lead to temporary paralysis. It's important to recognize the symptoms because prompt treatment can significantly improve recovery.
Clinical Overview
Guillain-Barré Syndrome (GBS) is an acute, immune-mediated polyradiculoneuropathy characterized by rapid onset of ascending symmetrical weakness and sensory changes. It is typically triggered by an infection, leading to autoantibodies targeting peripheral nerve components.
Clinical Presentation
- Rapidly progressive, symmetrical ascending motor weakness, often starting in the lower extremities and progressing upwards.
- Sensory disturbances, including paresthesias (tingling, numbness), dysesthesias, and pain, often preceding or accompanying motor deficits.
- Areflexia or hyporeflexia in affected limbs.
- Cranial nerve involvement, leading to facial weakness, dysphagia, ophthalmoplegia, and dysarthria.
- Autonomic dysfunction, manifesting as fluctuations in heart rate and blood pressure, urinary retention, and paralytic ileus.
Signs & Symptoms
Symptoms (Patient-Reported)
- Tingling or prickling sensations, often starting in the feet and hands.
- Sudden onset of muscle weakness that spreads upwards from the legs.
- Difficulty walking or climbing stairs.
- Pain, which can be severe and described as aching or cramping.
- Difficulty with facial movements, such as chewing, swallowing, or speaking.
- Double vision or inability to move eyes.
- Loss of bladder or bowel control.
Signs (Clinician-Observed)
- Diminished or absent deep tendon reflexes (areflexia/hyporeflexia).
- Symmetrical flaccid paralysis.
- Facial muscle weakness (e.g., ptosis, facial diplegia).
- Ophthalmoparesis or ophthalmoplegia.
Differential Diagnoses
| Condition | Distinguishing Feature |
|---|
| Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) | CIDP has a subacute or chronic course (months to years) rather than the acute onset of GBS, and often shows relapsing-remitting patterns. |
| Botulism | Botulism typically presents with descending paralysis, cranial nerve palsies (especially ophthalmoplegia and ptosis), and often intact sensation and reflexes, unlike the ascending weakness and areflexia of GBS. |
| Tick Paralysis | Caused by a neurotoxin from a tick bite, it presents with ascending paralysis that resolves rapidly after tick removal. Absence of sensory symptoms and a history of tick exposure are key. |
| Myasthenia Gravis | Myasthenia gravis is characterized by fluctuating weakness that worsens with activity and improves with rest, often affecting ocular and bulbar muscles early. Reflexes are typically preserved. |
| Transverse Myelitis | Transverse myelitis involves inflammation of the spinal cord, leading to weakness, sensory deficits, and autonomic dysfunction below the level of the lesion, with a distinct sensory level. |
| Poliomyelitis | Poliomyelitis causes asymmetric flaccid paralysis with preserved sensation and reflexes, and is now rare due to vaccination. |
Red Flags — Seek Immediate Care
- Rapidly progressive weakness, especially if affecting respiratory muscles.
- Difficulty breathing or swallowing.
- Autonomic instability (severe fluctuations in blood pressure or heart rate).
- Ascending paralysis reaching the trunk or diaphragm.
Key Investigations
- Cerebrospinal fluid (CSF) analysis via lumbar puncture: typically shows albuminocytologic dissociation (high protein with normal or mildly elevated white blood cell count).
- Nerve conduction studies (NCS) and electromyography (EMG): demonstrate demyelination and/or axonal damage, with characteristic findings like prolonged distal motor latencies, reduced conduction velocities, and conduction block.
- Pulmonary function tests (PFTs): to assess respiratory muscle strength and guide mechanical ventilation decisions.
- Cardiac monitoring: to detect and manage autonomic dysfunction.
Management Overview
Management of GBS is primarily supportive and aims to mitigate complications while facilitating nerve recovery. Evidence-based treatments include intravenous immunoglobulin (IVIg) or plasma exchange (PLEX) to reduce the duration and severity of the illness. Close monitoring for respiratory compromise and autonomic dysfunction is crucial, with mechanical ventilation and cardiovascular support as necessary.
