[The value of EEG mapping in intracerebral hematomas].

Abstract

33 patients with intracerebral hemorrhage were studied and the findings of EEG mapping, routine EEG and CT were compared. It could be shown, that the EEG mapping revealed in 6 patients additional focal changes corresponding with the clinical signs compared to conventional EEG. Identical results of EEG mapping and CT were found in 27 patients. In 5 patients the focal changes were localised contralateral to the hyperdense lesion in CT, and in 1 patient the EEG mapping failed to show any lateralisation. A negative intercorrelation between the size of the hematoma and the frequency, which revealed the focal signs in EEG mapping, could be shown.
