Guillain-Barre syndrome is an acute inflammatory polyneuropathy that is classified according to symptoms and divided into axonal and demyelinating forms.
Two-thirds of patients have a history of gastroenteritis or influenza-like illness weeks before onset of neurologic symptoms.
Associated with Zika virus outbreaks.
Up to 30% will develop respiratory muscle weakness requiring ventilation.
Neurophysiology is confirmatory and is abnormal in 85% of patients, even early in the disease.
Lumbar puncture is useful, and the classic finding is elevated protein with normal cell count (albuminocytologic dissociation).
Treatment combines supportive and disease-modifying therapy (plasma exchange or high-dose immune globulin).
Guillain-Barre syndrome (GBS) is an acute inflammatory neuropathy. It is a clinically defined syndrome characterized by motor difficulty, absence of deep tendon reflexes, paresthesias without objective sensory loss, and increased cerebrospinal fluid albumin with absence of cellular reaction (albuminocytologic dissociation). Acute inflammatory demyelinating polyradiculoneuropathy is the most commonly encountered variant.
