Abstract: Six patients with ataxia-telangiectasia were given neurophysiological examinations. The patients had progressive sensorimotor axonal neuropathy that had begun at about age eight years. Brainstem auditory evoked potentials (BAEPs) showed central alterations in two of four cases. Somatosensory (BAEPs) and motor evoked potentials (MEPs) were altered in four of five cases. In the advanced stage of the disease the neurophysiological findings, except BAEPs and MEPs, resembled those in Friedreich's ataxia. MEP and BAEP results may therefore be useful for differential diagnosis.
