Bickerstaff’s brainstem encephalitis (BBE) is a Fisher Syndrome (FS) related disorder characterized by the disturbance of consciousness or hyperreflexia in addition to the classical triad of ataxia, areflexia and ophthalmoplegia. The pathophysiology of BBE remains controversial therefore a complete neurophysiological study including the study of cranial nerves may be crucial to add evidence of peripheral or central nervous system involvement in the assessment of patients. We report the case of 29 years old woman with BBE and the blink reflex (BR) follow up studies revealing a correlation between clinical and electrophysiological improvement. This case may support the usefulness of BR studies for electrophisiological diagnosis in BBE in early stages.
