All forms of Guillain-Barré syndrome are due to an immune response to foreign antigens (such as infectious agents or vaccines) but mistargeted to host nerve tissues instead (a form of [[antigenic mimicry]]). The targets of such immune attack are thought to be [[gangliosides]], which are complex glycosphingolipids present in large quantities on human nerve tissues, especially in the [[nodes of Ranvier]]. An example is the GM1 ganglioside, which can be affected in as many as 20-50% of cases, especially in those preceded by ''[[Campylobacter jejuni]]'' infections. Another example is the GQ1b ganglioside, which is the target in the Miller Fisher syndrome variant (see below).
== [[Guillain-Barré syndrome classification|Classification]] ==


The end result of such [[autoimmune]] attack on the peripheral nerves is inflammation of [[myelin]] and conduction block, leading to a muscle [[paralysis]] that may be accompanied by sensory or [[autonomic]] disturbances.
== [[Guillain-Barré syndrome pathophysiology|Pathophysiology]] ==


However, in mild cases, axonal function remains intact and recovery can be rapid if remyelination occurs. In severe cases, such as in the AMAN or AMSAN variants (see below), axonal degeneration occurs, and recovery depends on axonal regeneration. Recovery becomes much slower, and there is a greater degree of residual damage. Recent studies on the disease have demonstrated that approximately 80% of the patients have [[myelin]] loss, whereas, in the remaining 20%, the pathologic hallmark of the disease is indeed [[axon]] loss.

The disease is characterized by weakness which affects the lower limbs first, and rapidly progresses in an ascending fashion. Patients generally notice weakness in their legs, manifesting as "rubbery legs" or legs that tend to buckle, with or without [[dysthesias]] (numbness or tingling). As the weakness progresses upward, usually over periods of hours to days, the arms and facial muscles also become affected. Frequently, the lower [[cranial nerves]] may be affected, leading to bulbar weakness, (oropharyngeal dysphagia, that is difficulty with swallowing, drooling, and/or maintaining an open airway) and respiratory difficulties. Most patients require hospitalization and about 30% require ventilatory assistance. Facial weakness is also commonly a feature, but eye movement abnormalities are not commonly seen in ascending GBS, but are a prominent feature in the Miller-Fisher variant (see below.)
== [[Guillain-Barré syndrome risk factors|Risk Factors]] ==


Sensory loss, if present, usually takes the form of loss of [[proprioception]] (position sense) and areflexia (complete loss of deep tendon reflexes), an important feature of GBS. Loss of pain and temperature sensation is usually mild. In fact, pain is a common symptom in GBS, presenting as deep aching pain usually in the weakened muscles, which patients compare to the pain from overexercising. These pains are self-limited and should be treated with standard analgesics. Bladder dysfunction may occur in severe cases but should be transient. If severe, spinal cord disease should be suspected.
== [[Guillain-Barré syndrome natural history, complications, and prognosis|Natural history, Complications and Prognosis]] ==


Fever should not be present, and if it is, another cause should be suspected.
== Diagnosis ==


In severe cases of GBS, loss of autonomic function is common, manifesting as wide fluctuations in blood pressure, [[orthostatic hypotension]], and cardiac arrhythmias.
