Abstract:
Objective To explore the relationship between EEG feature and TCD with secondary epileply in cerebrul infarction.Methods EEG and TCD were done and analyzed in 40 patients with secondary epileply in cerebrul infarction.Results The EEG abnormality rate was 95%,TCD abnormaity rate was 87.5%,abnormal EEG mainly showed increase of slow waves with low to middle amplitude,with diffuse or local distribution,epileptiform discharges were foumd only in 9 of the 38 ones,cerebral blood flow(CBF) was increased,decreased or bilateral dissymmetry,abnormal spectral frequency(higher force).Conclusion The abnormality rate of EEG is higher,but the detection rate of epileptiform discharges is lower;Unilateral increased of CBF might predict the side of epileptogenic focus.
