Abstract
Brainstem auditory (BAEP) and somatosensory (SEP) evoked potentials to median and peroneal nerve stimulation were investigated in 25 patients with neurodegenerative system disorders: 9 Friedreich’s ataxia, 7 hereditary motor sensory neuropathies, 3 familial spastic paraplegia, 3 olivopontocerebellar atrophy, 1 ataxia telangiectasia and 1 abetalipoproteinemia, BAEPs were abnormal in 39%, SEPs to both upper- and lower-limb stimulation were abnormal in 63%. Serial evoked potential testing paralleled the clinical progression. SEPs were more frequently and severely altered than BAEPs suggesting that SEP testing may be a more sensitive indicator of early involvement of afferent pathways in these disorders.
