Abstract Objective: To study the diagnostic value of ambulatory electroencephalogram (AEEG) and video electroencephalogram (VEEG) in children with non-convulsive seizures (NCS). Methods: 82 patients diagnosed as NCS in our hospital from January 2016 to January 2018 were included in the study and given retrospective analysis. All patients were given routine electroencephalogram (REEG), and 56 patients were given 24h AEEG, and 78 patients were given VEEG. Diagnostic value of 24hAEEG and VEEG in NCS was analyzed. Results: 56 children patients were given 24h AEEG examination, and the abnormal discharge rate, epileptic discharge rate and detection rate of clinical seizures were significantly higher than those of REEG (P<0.05). 78 children patients were given VEEG examination, among which 59 cases were with seizure events and 6 cases were with abnormal discharge during seizure, and 57 cases were finally confirmed by combining with past history, family history and neurological examination of children patients. And the seizure events rate and abnormal discharge rate during seizure of VEEG were significantly higher than those of REEG (P<0.05). VEEG suggested that all children patients had somatic NCS seizures, among which 50 cases (87.72%) were non-convulsive tonic seizures and the remaining 7 cases (12.28%) were benign myoclonus. Conclusions: Compared with REEG, 24hAEEG can effectively prolong the monitoring time and increase the positive rate of capture events, but the examination results are greatly disturbed by the activities of children patients or parents, and VEEG achieves the simultaneous recording of electroencephalogram and seizure status, and it has highest diagnostic value.
