The objective of this study was to test statistical features from the electroencephalogram (EEG) recordings as predictors of neurodevelopment and cognition of Ugandan children after coma due to cerebral malaria. The increments of the frequency bands of EEG time series were modeled as Student processes; the parameters of these Student processes were estimated and used along with clinical and demographic data in a machine-learning algorithm for the prediction of children's neurodevelopmental and cognitive scores 6 months after cerebral malaria illness. The key innovation of this work is in the identification of stochastic EEG features that can serve as language-independent markers of the impact of cerebral malaria on the developing brain. The results can enhance prognostic determination of which children are in most need of rehabilitative interventions, which is especially important in resource-constrained settings such as sub-Saharan Africa.
本研究的目的是测试脑电图(EEG)记录中的统计特征,作为乌干达儿童因脑型疟疾昏迷后神经发育和认知的预测指标。EEG时间序列频段的增量被建模为学生过程;估计这些学生过程的参数,并将其与临床和人口统计学数据一起用于机器学习算法,以预测脑型疟疾发病6个月后儿童的神经发育和认知得分。这项工作的关键创新在于识别随机EEG特征,这些特征可作为脑型疟疾对发育中大脑影响的与语言无关的标志物。研究结果可加强对哪些儿童最需要康复干预的预后判定,这在撒哈拉以南非洲等资源有限的地区尤为重要。
