In 1957, Chambers and MacDermot2 reported a case of acute polyneuritis causing "amyotonia congenita" starting at 3 months of age, but whether or not this case fits the criteria of the Guillain-Barré syndrome is questionable, and will be discussed subsequently. In a study relating to the clinical value of motor nerve conduction velocity determination,3 a case of a 6-month-old infant is presented, with infectious neuronitis but no spinal fluid finding included in the protocol, and so again the diagnosis of Guillain-Barré syndrome may be open to question.
