Overview
Guillain-Barré syndrome (GBS) is an acute, autoimmune, polyradiculoneuropathy affecting the peripheral nervous system, usually triggered by an acute infectious process. It is included in the wider group of peripheral neuropathies. There are several types of GBS, but unless otherwise stated, GBS refers to the most common form, acute inflammatory demyelinating polyneuropathy (AIDP). It is frequently severe and usually exhibits as an ascending paralysis noted by weakness in the legs that spreads to the upper limbs and the face along with complete loss of deep tendon reflexes. However, death may occur if severe pulmonary complications and dysautonomia are present.
History and symptoms
History
- Patients may present with a history of antecedence benign infection of gut or respiratory tract, 2-4 weeks prior to the development of symptoms.
- Symptoms can get worse very quickly. It may take only a few hours to reach the most severe symptoms, however weakness increasing over several days is also common.
- The mean time to the clinical function peak is 2 weeks, with most of the patients reaching a nadir by 4 weeks.
- This is usually followed by a plateau phase characterized by persistent, unchanging symptoms.
- The plateau phase may last for days before initiation of gradual symptoms improvement.
- Recovery usually starts 2-4 weeks after the progression of symptoms ceases.
- The mean time to clinical recovery is 15-20 weeks
Symptoms
- Fever is uncommon and, and if it is present, another cause should be suspected. The initial symptoms in many patients may be tingling, numbness, pain or clumsiness sensation of the hands and foot.
Motor
- The initial symptoms may be followed by development of weakness. The weakness may be characterized by the following features:
- It usually affects the legs first, and rapidly progresses (hours to days) in an ascending fashion to involve trunk, upper limb, face, and other parts of the body.
- Patients generally notice weakness in their legs, manifesting as "rubbery legs" or legs that tend to buckle easily.
- Proximal muscles are affected more commonly and patient may presents with difficulty in standing from sitting position
- The weakness usually affects both sides of the body.
- It may rarely begin in the arms and legs at the same time
- It may rarely start in the arms and move downward
- In mild cases, there may be no weakness or paralysis
- Respiratory difficulties secondary to respiratory muscle weakness may be seen. Most patients require hospitalization and about 30% require ventilatory assistance.
Sensory
- Loss of position sense, pain and temperature sensation may present. Loss of pain and temperature sensation is usually mild.
- On contrary, patient may present with deep aching pain usually in the weakened muscles, which they compare to the pain from overexercising.
Autonomic
- Dizziness on standing from sitting or lying position (orthostatic hypotension) and awareness of self heartbeat (Palpitations) (autonomic involvement)
Cranial nerve
- Blurred vision
- Eye movement abnormalities are not commonly seen in ascending GBS, but are a prominent feature in the Miller-Fisher variant
- Difficulty in swallowing and drooling of saliva.
- Facial weakness may also be seen.
- Uncoordinated movements presenting as clumsiness in walking and history of fall may be seen.
Emergency symptoms (seek immediate medical help)
- Difficulty breathing
- Difficulty swallowing
- Drooling
- Fainting
- Feeling light-headed when standing
