Abstract
Objective: This study aimed to compare video electroencephalogram (VEEG) and routine electroencephalogram (EEG) in childhood epilepsy diagnosis and analyze the correlation between EEG frequency band power and cognitive impairment severity.
Methods: One hundred and sixty children suspected of having epilepsy underwent routine EEG and VEEG examinations. Diagnostic efficacy and detection rates were compared. Cognitive function was evaluated in 80 children diagnosed with epilepsy, who were allocated into normal intelligence (35 cases), borderline intelligence (25 cases), and intelligence-impaired (20 cases) groups. Clinical data, EEG parameters, and their correlation with cognitive impairment were analyzed.
Results: VEEG showed higher sensitivity, accuracy, and negative predictive value, and detection rates of epileptiform discharges, synchronous clinical seizures, and clinical symptoms than routine EEG (p < 0.05). Clinical characteristics and EEG parameters differed among the three groups (p < 0.05). The relative power of δ and θ bands and the awake and sleep discharge indices were positively correlated with cognitive impairment severity (r = 0.300, 0.643, 0.622, and 0.456), whereas α and β band power were negatively correlated (r = -0.515 and -0.410) (all p < 0.001).
Conclusion: VEEG demonstrated higher diagnostic performance than routine EEG, and EEG frequency band power was correlated with cognitive impairment severity.
目的:比较视频脑电图(VEEG)与常规脑电图(EEG)对儿童癫痫的诊断价值,分析脑电图频带功率与认知功能障碍严重程度的相关性。方法:对160例疑似癫痫患儿进行常规脑电图和脑电图检查。比较两组的诊断效率和检出率。80例癫痫患儿被分为正常智力组(35例)、边缘智力组(25例)和智力受损组(20例),对其进行认知功能评估。分析临床资料、脑电图参数及其与认知功能障碍的相关性。结果:VEEG的敏感性、准确性、阴性预测值均高于常规脑电图(p p p),癫痫样放电、同步临床发作、临床症状的检出率均高于常规脑电图(p p p p)。结论:VEEG的诊断性能优于常规脑电图,且脑电图频带功率与认知功能障碍严重程度相关。
期刊介绍:
Applied Neuropsychology: Child publishes clinical neuropsychological articles concerning assessment, brain functioning and neuroimaging, neuropsychological treatment, and rehabilitation in children. Full-length articles and brief communications are included. Case studies of child patients carefully assessing the nature, course, or treatment of clinical neuropsychological dysfunctions in the context of scientific literature, are suitable. Review manuscripts addressing critical issues are encouraged. Preference is given to papers of clinical relevance to others in the field. All submitted manuscripts are subject to initial appraisal by the Editor-in-Chief, and, if found suitable for further considerations are peer reviewed by independent, anonymous expert referees. All peer review is single-blind and submission is online via ScholarOne Manuscripts.
