Abstract

Yoshii and Kudo [354, 355] were the first to point out the appearance of slow waves due to hyperventilation in the electroencephalograms (EEG) of juvenile cases of moyamoya disease. Such slow waves, however, subsequently came to be considered simply as a buildup phenomenon or its prolongation [116, 348]. In other reports [212, 354] it was considered to be merely a nonspecific response seen during cerebral circulatory insufficiency. Since those early studies, we have reported on the monorhythmic posterior slow waves seen in juvenile moyamoya disease and have found that the changes seen after hyperventilation are not merely buildup or its prolongation, but that subsequent to the disappearance of slow waves. Moreover, the shape of the waves seen in moyamoya disease is distinct from such buildup, which we have labeled “re-buildup.” These EEG findings are characteristic of juvenile moyamoya disease and we have frequently emphasized the fact that EEG examination is an effective means of screening for juvenile moyamoya disease [8, 9, 74, 135, 269].
