Guillain-Barré Syndrome and Swallowing Dysfunction

Area of Science:

• Neurology
• Gastroenterology
• Clinical Electrophysiology

Background:

• Guillain-Barré syndrome (GBS) frequently causes swallowing difficulties, particularly in severe cases requiring intensive care.
• Oropharyngeal function in non-intensive care GBS patients is often unassessed by neurophysiological methods.

Purpose of the Study:

• To evaluate the utility of neurophysiological techniques for assessing oropharyngeal function in GBS patients not requiring intensive care.
• To determine dysphagia limits and sequential water swallowing values in GBS patients.

Main Methods:

• Electrophysiological techniques were employed in an electromyography laboratory.
• Dysphagia limit and sequential water swallowing tests were performed on 18 GBS patients and 18 healthy controls.

Main Results:

• Seven of 18 GBS patients showed clinical dysphagia, with five exhibiting silent dysphagia despite normal cranial nerve involvement.
• Swallowing duration was significantly prolonged in all GBS patients compared to controls.
• Cranial nerve involvement correlated with a higher incidence of oropharyngeal dysphagia.

Conclusions:

• Neurophysiological techniques are safe, applicable, and valuable for assessing dysphagia in GBS patients.
• Subclinical oropharyngeal dysphagia is common in GBS patients.
• These techniques should be used for initial assessment and follow-up in all GBS patients.
