Guillain–Barré syndrome mimics

The Brighton Collaboration criteria have standardized the clinical and laboratory‐supported diagnosis of Guillain–Barré syndrome (GBS) and Miller Fisher syndrome (MFS) in a way that is applicable in many parts of the world with variable resources. The caveat within the criteria, “absence of an identified alternative diagnosis for weakness” makes GBS a diagnosis of exclusion. Accurate diagnosis of GBS requires a good understanding of an updated, locally contextualised list of mimics, and features that distinguish them from GBS. [Image: see text]
