Abstract:
Objective To analyze the clinical and electroencephalogram(EEG)characteristics of nonepileptic seizures in low aged children younger than 6 years.Methods The case data of low-aged children younger than 6 years who were admitted to the Affiliated Children's Hospital of Capital Institute of Pediatrics from July 2019 to July 2021 with episodic symptoms as the main complaint and under-went video EEG monitoring were retrospectively analyzed.According to the patient's clinical symptoms and signs,combined with the video EEG monitoring results,the diagnosis was made by two neurologists.To summarize the clinical characteristics of nonepileptic seizures,and analyze the characteristics of video EEG.Results A total of 433 cases of nonepileptic seizures were recorded by video EEG,inclu-ding 398 cases(91.9％)of physiological nonepileptic seizures and 35 cases(8.1％)of psychogenic nonepileptic seizures.Interparoxys-mal epileptic discharges were detected in 24 cases(5.5％,24/433),and 15 cases(3.5％)in Rolandic region were the most common.The motor seizures were most common(392 cases,90.5％).There were 41 cases(9.5％)of non-motor seizures.Nonepileptic my-oclonic seizures were the most common in nonepileptic seizures.The number of men with physiological nonepileptic seizures was more than that of women,and the number of women with psychogenic nonepileptic seizures was more than that of men.There was significant differ-ence in gender composition between the groups(x2=12.513,P＜0.001).The proportion of psychogenic nonepileptic seizures in the 1-3 years group was significantly higher than that in the 0-1 year group(x2=8.713,P=0.003),but there was no statistical difference compared with the 3-6 years group(x2=5.253,P=0.022).Conclusion The EEG of nonepileptic seizures in low-aged children younger than 6 years is mostly normal,the epileptic discharge rate is low in the interictal period,and there is no characteristic EEG change in the interseizure period,the interictal background EEG can be used as a diagnostic reference.The clinical characteristics of non-epileptic seizures in low-aged children younger than 6 years are complex and diverse,mainly physiological nonepileptic seizures,and nonepileptic myoclonic seizures are the most common.Psychogenic nonepileptic seizures are relatively common in children aged 1-3 years.
