Abstract:
In recent days quantitative electroencephalography (QEEG) has grown rapidly and QEEG techniques and EEG mapping have shown localizing functional imaging. We report two cases of falsely lateralized EEG mapping in stroke patients. Both cases had right hemispheric stroke, but presented bilateral clinical symptoms. Contrary to structural imaging, EEG mapping displayed left hemispheric dysfunction and SPECT displayed bilateral perfusion Aegects. These findings suggest that false lateralization of EEG mapping in unilateral stroke patients may show bilateral cerebral dysfunction not detected in conventional imaging technique.
