Abstract
The potential for clinical application of computed EEG topography (CET) has been known since 1978. However, studies relating to the focal brain lesions are few. We have studied 19 cases of acute stroke involving the cerebral hemispheres. CET and EEG were recorded as soon as possible, usually within 1-3 days of onset. Repeat maps were recorded at 1 wk. Symptoms, neurologic exam, routine EEG and CT scan were compared with the CET of power spectral and flash evoked potential data. Statistical criteria were also applied. Good correlation was noted between CET and EEG and CT. Occasionally, CET was noted to provide information beyond EEG or CT. These early studies suggest a potential utility for CET in the early diagnosis of stroke.
