[Article in French]


Somatosensory evoked potentials (SEPs) were studied in 21 cases of amyotrophic lateral sclerosis (ALS) and 7 cases of primary lateral sclerosis (PLS). Despite the lack of clinical sensory abnormalities, SEPs showed abnormalities in both diseases: lack or delay of some components. In ALS these abnormalities indicate widespread sensory disturbance. In PLS only, the Brodmann area 4 seems to be affected.
