Polygraphic study of nocturnal sleep in three degenerative diseases: ALS, oligo-ponto-cerebellar atrophy, and progressive supranuclear palsy
Waking Sleeping, 3 (1):
17--30 (January 1979)Abstract
A polygraphic study of nocturnal sleep was carried out on 12 patients suffering from amyotrophic lateral sclerosis (ALS), 6 patients suffering from olivio-ponto-cerebellare-atrophia (OPCA) and 9 patients suffering from the Steele-Richardson disease (SR). A disturbance of sleep--if it exists--always runs parallel with the course of the disease. No disturbances were registered in the group of patients suffering from ALS, in the OPCA group a specific disease of paradoxal sleep is observed. The sleep disturbances are more global in the group of patients suffering from the SR disease. A particular electrooculogram was taken from the patients from the awakening and from the paradoxal sleep. Respiratory difficulties were registered on certain patients of each of the three groups. These sleep disturbances, registered by the polygraph, were compared with those observed on patients presenting a cortical disease.
