METHODS: The dataset is composed of 10 MCI and 10 HC groups. Spectral features and synchrony measures are utilized to detect slowing patterns in MCI. Efficient neuro-markers are classified by 25 classification algorithm. Independent samples t-test and Pearson\'s Correlation Coefficients are applied to reveal group differences for spectral markers, and repeated measures ANOVA is tested for wPLI-based markers.
RESULTS: Lower peak amplitudes are prominent in MCI participants for high frequencies indicating slower physiological behavior of the demented EEG. The MCI and HC groups are correctly classified with 95 % acc. using peak amplitudes of beta band with LGBM classifier. Higher wPLI values are calculated for HC participants in high frequencies. The alpha wPLI values achieve a classification accuracy of 99 % using the LGBM algorithm for MCI detection.
METHODS: The neuro-markers including peak amplitudes, frequencies, and wPLIs with advanced machine learning techniques showcases the innovative nature of this research.
CONCLUSIONS: The findings suggest that peak amplitudes and wPLI in high frequency bands derived from resting state EEG are effective neuromarkers for detection of MCI. Spectral and synchrony neuro-markers hold great promise for accurate MCI detection.
方法:数据集由10个MCI和10个HC组组成。利用光谱特征和同步性度量来检测MCI中的减慢模式。通过分类算法对有效的神经标记进行分类。独立样本t检验和皮尔逊相关系数用于揭示光谱标记的群体差异,和重复测量方差分析测试基于wPLI的标志物。
结果:对于高频率,MCI参与者的峰值振幅较低,表明痴呆脑电图的生理行为较慢。MCI和HC组被正确地分类为95%acc。用LGBM分类器使用β波段的峰值振幅。在高频中为HC参与者计算更高的wPLI值。使用用于MCI检测的LGBM算法,alphawPLI值实现99%的分类准确度。
■神经标记包括峰值振幅,频率,具有先进机器学习技术的wPLI展示了这项研究的创新性。
结论:研究结果表明,静息状态EEG的高频带中的峰值幅度和wPLI是检测MCI的有效神经标志物。光谱和同步神经标记物对于准确的MCI检测具有很大的前景。
