We examined a nosological position of Bickerstaff s brainstem encephalitis (BBE) as referring to original cases [Bickerstaff and Cloake (1951) ; Bickerstaff (1957)]. Patients, who show drowsiness, brisk reflexes, extensor plantar responses, hemisensory disturbance, cerebral hemisphere signs and Parkinsonism in addition to acute ophthalmoplegia and cerebellar ataxia, usually were diagnosed to have BBE rather than Fisher's syndrome. IgG anti-GQ1b antibody was detected in BBE, which suggests that this conditions are categorized as autoimmune diseases related to Fisher's syndrome. The symptoms of fever (92%), headache (33%), general malaise (33%) often preceded and a half of patients had a history of sore throat and cough before the onset of neurological symptoms. Cases of BBE were found associated with herpes simplex virus, Epstein-Barr virus, echo virus, adeno virus, Salmonella typhi, measles virus, cytomegalovirus, and Mycoplasma pneumoniae as antecedent infec-tious agents.
