Specific alterations of EEG tracings with Moyamoya syndrome are only observed in children. They consist in a gradual frequency decrease and amplitude activation after hyperventilation. This is referred to as re-build-up phenomenon. Thus, a tentative diagnosis of Moyamoya syndrome in children may be based on the EEG finding, to be radiologically confirmed by angiography.
