A Patient-Independent Neonatal Seizure Prediction Model Using Reduced Montage EEG and ECG

  • 融合脑电心电特征,用卷积神经网络区分发作间期与前发作期。
  • 在10折交叉验证下准确率达97.52%,最早可提前30分钟预警。
  • 模型跨患者通用,且通过可视化解释提升临床可信度。

新生儿易发癫痫,常导致短期或长期神经损伤。但其临床表现隐匿,易误诊,增加未及时治疗的风险及脑损伤概率。持续视频脑电图(cEEG)是癫痫检测金标准,但成本高、需专业人员。本研究提出一种基于卷积神经网络的患者无关模型,通过区分脑电(EEG)的发作间期与前发作期,实现早期癫痫预测。模型采用多通道EEG与心电图(ECG)提取的梅尔频率倒谱系数矩阵作为输入特征,在赫尔辛基新生儿脑电数据集上进行10折交叉验证,平均准确率97.52%、灵敏度98.31%、特异性96.39%、F1分数97.95%,可提前30分钟预测癫痫发作。引入ECG使F1分数提升1.42%,加入注意力机制再提升0.5%。通过SHAP可解释性方法增强透明度,并利用头皮图定位癫痫灶。结果表明该模型具备强泛化能力,适合在新生儿重症监护室中进行低监督部署,实现及时可靠的癫痫预警。

原文摘要 · Abstract (English)

Neonates are highly susceptible to seizures, often leading to short or long-term neurological impairments. However, clinical manifestations of neonatal seizures are subtle and often lead to misdiagnoses. This increases the risk of prolonged, untreated seizure activity and subsequent brain injury. Continuous video electroencephalogram (cEEG) monitoring is the gold standard for seizure detection. However, this is an expensive evaluation that requires expertise and time. In this study, we propose a convolutional neural network-based model for early prediction of neonatal seizures by distinguishing between interictal and preictal states of the EEG. Our model is patient-independent, enabling generalization across multiple subjects, and utilizes mel-frequency cepstral coefficient matrices extracted from multichannel EEG and electrocardiogram (ECG) signals as input features. Trained and validated on the Helsinki neonatal EEG dataset with 10-fold cross-validation, the proposed model achieved an average accuracy of 97.52%, sensitivity of 98.31%, specificity of 96.39%, and F1-score of 97.95%, enabling accurate seizure prediction up to 30 minutes before onset. The inclusion of ECG alongside EEG improved the F1-score by 1.42%, while the incorporation of an attention mechanism yielded an additional 0.5% improvement. To enhance transparency, we incorporated SHapley Additive exPlanations (SHAP) as an explainable artificial intelligence method to interpret the model and provided localization of seizure focus using scalp plots. The overall results demonstrate the model's potential for minimally supervised deployment in neonatal intensive care units, enabling timely and reliable prediction of neonatal seizures, while demonstrating strong generalization capability across unseen subjects through transfer learning.
