Abstract
Attempts were made to evaluate the EEG findings in 34 children and 28 adults with Moyamoya disease.
1) The children revealed specific findings such as posterior slow, centrotemporal slow and Rebuild up after the end of hyperventilation.
2) Posterior slow was observed in EEG with high frequency examined within one year after the initial onset. After one year from the initial onset, centrotemporal slow was revealed. After 3 years and a half from the onset diffuse inactive pattern was observed.
3) Rebuild up was most characteristic findings in children Moyamoya.
4) In adults moyamoya, no specific findings have been observed yet.
