Comparison and analysis of conventional and ambulatory electroencephalography in patients with epileptic seizures post stroke.

Objective To compare and analyze conventional and ambulatory electroencephalography(EEG,and AEEG)in patients with poststroke seizures.Methods Forty patients with epileptic seizures post stroke were included in the present study.All patients underwent EEG and AEEG examinations and the EEG records were further clarified as normal,mild abnormal,middle abnormal,and sever abnormal.Results The lesions most frequently occurred in the temporal and frontal lobes and thalamus in patients with poststroke epileptic seizures.The main type of epileptic seizures was generalized seizures.The rate of abnormal EEG was 47.5% of which 52.6% abnormal EEG are mild and 47.4% moderate to severe in severity.The rate of abnormal AEEG was 80% of which only 12.5% abnormal AEEG are mild and 87.5% moderate to severe in severity.Statistic analysis with Chi-square Test showed P0.005 which indicates that AEEG examination enhanced the EEG sensitivity for seizure detection.Conclusions AEEG examination can enhance the EEG sensitivity for seizure detection in patients with poststroke seizure and may therefore be helpful for guiding the clinic treatment.
