Abstract:
Objective To explore the clinical significance of EEG and CT presentations in the patients with acute ischemic stroke. Methods Fifty-six consecutive patients with acute ischemic stroke admitted immediately after the onset were enrolled in this study.Thefindings bYCT,EEG,brain electrical activity mapping(BEAM),examinations of somatosensory evoked potentials(SEPs)and motor evoked potentials(MEPs)to transcranial magnetic stimulation, and the scores of modified Edinburgh-Scandinavia stroke scale(MESSS)and Barthel Index(BI)were comparatively analyzed in these patients. Results The location of the cerebral foci with EEG abnormalities were basically consistent with the lesions indentified by CT.but the range of the lesions defined by the two modalities showed some discrepancies.There Was statistically significant difference in SEP and MEP between the injured and uninjured sides(P<0.05).There was apositive correlation between MESSS on admission and BI on day 28 in hospital(r=0.58,P<0.05). Conclusion CT and cerebral electrophysiological examination provide valuable assistance in early diagnosis of acute ischemic stroke.
