[Electroencephalographic and computer-tomographic correlations in cerebral circulatory disorders]

The results of electroencephalographic (EEG) and computer-aided tomographic (CT) examinations were compared in order to specify the possibilities of EEG in the topical diagnosis in cases of the compromised cerebral circulation (a hundred patients had been studied). The CT and EEG findings were closely correlated (80%) when the focus was localized in the hemispheres; discrepancies were observed (20%) in cases of extensive haemorrhages, with blood invading the ventricular system, in cases of microfoci lying in the deep portions of the cerebral hemispheres and also when foci were present in both hemispheres. In cases of the trunk localization of the focus, the EEG and CT findings were correlated in only 37%. The discrepancies of the two methods predominantly concerned impairments of the lower portions of the trunk where the EEG technique proved more informative.
