A comparison of the results of topographic EEG mapping with the data from a neurological examination and computed tomography of the brain
: The data of topographic EEG brain mapping were compared to neurological evidence and CT data in 6 patients with organic lesions (sequelae of vertebrobasilar ischemic stroke, brain atrophy, brain tumor). Cortical activity typical for these nosological entities appeared on the EEG maps. In 5 out of 6 patients foci of alpha- and delta-activity indicated the location of the lesion. The authors suggest that EEG brain mapping of the large number of patients with neural and mental diseases will provide insight into pathogenetic mechanisms of these diseases. The authors also think it necessary for patients undergoing EEG brain mapping to be examined neurologically.
