Abstract

With 4-Channel Nicolet-CA 1000 clinical averager, somatosensory evoked potentials(SSEP) and brainstem auditory evoked potentials(BAEP) were studied in 40 patients with intracerebral hematoma and 40 patients with cerebral infarction. SSEP was more sensitive response in putamen(20/23) or thalamic(6/7) hemorrhage and infarction of middle cerebral artery territory(13/28). in contrast BAEP was high percentage in abnormality in brainstem or cerebellar lesion. Cortical wave(N18) was usually not traceable in large size of hematoma or having midline shift in brain CT scan. There was close correlation between the severity of motor weakness and abnormality of SSEP. The best neurological outcome was found in the patients of P24 wave formation. In our results, SSEP and BAEP seemed to be very useful for evaluation of stroke patients.
