title: A case report on EEG nocturnal sleep in visually impaired persons aged in their 30s and 50s.
abstract: To determine the EEG sleep structure in visually impaired persons, EEG sleep recordings were made over two or three consecutive nights on five subjects in their 30s and 50s in the laboratory or in the Welfare Center for the Blind. Sleep variables were compared to the normative data of sighted persons of comparable ages. The results indicated that the percentages of slow wave sleep in four of the five blind individuals were much less than the values of the normative data, which is in agreement with Krieger and Glick's results (1971).
