Abstract

Objective. To measure the EEG signals of the people with chronic stroke in eyes-closed and eyes-open condition and study their relationship with the cognitive function and mental wellbeing. Methods. The investigators would conduct cognitive and mental wellbeing tests on recruited subjects. Their EEG signal was acquired by the 16-channel EEG system. The absolute power under different frequency bands and EEG indices (delta alpha ratio and pairwise derived brain symmetry index) in different eye conditions was calculated. Pearson's correlation was conducted to investigate the association between the clinical tests and the EEG index. Results. 32 subjects were recruited for the study. There was a significant correlation between the pairwise derived brain symmetry index (pdBSI) in eyes-open condition with the Stroop Test (p = .002), Paced Auditory Serial Addition Test-3 s (p = .008)/2 s (p = .002) and WHO-5 well-being scale (p = .023). Conclusions. There is a significant correlation between the brain symmetry index and the cognitive and wellbeing assessment. Brain symmetry index over the delta frequency has been found to be the most useful parameter relating to the clinical score.Significance:It is recommended to use EEG as an adjunctive neuropsychological assessment in clinics for people with chronic stroke, especially for clients who could not undertake conventional assessments (eg aphasia, attention problem).Highlights: There is a significant correlation between the EEG index and the clinical neuropsychological assessmentPairwise Derived Brain Symmetry index in delta frequency range correlated with most of the neuropsychological outcome.It is feasible for us to adopt EEG as an adjunctive assessment in clinical settings.

慢性脑卒中患者脑电图的临床应用及其与神经心理学结果相关性的探索性研究。
客观的测量慢性脑卒中患者在闭眼和睁眼状态下的脑电信号,研究其和认知功能和心理健康的关系。方法。研究人员将对招募的受试者进行认知和心理健康测试。他们的脑电信号由16通道脑电系统采集。计算了不同频带下的绝对功率和不同眼睛条件下的EEG指数(delta-alpha比率和成对导出的大脑对称性指数)。采用Pearson相关性研究临床测试与脑电图指数之间的相关性。后果研究招募了32名受试者。在睁眼条件下,成对衍生的脑对称指数(pdBSI)与Stroop测试之间存在显著相关性(p = .002),起搏听觉序列加法测试-3 s(p = .008)/2秒(p = .002)和WHO-5幸福感量表(p = .023)。结论。大脑对称性指数与认知和幸福感评估之间存在显著相关性。德尔塔频率上的大脑对称性指数已被发现是与临床评分相关的最有用的参数。意义:建议在临床上使用脑电图作为慢性脑卒中患者的辅助神经心理学评估,特别是对于无法进行常规评估的客户(如失语症、注意力问题)。亮点:脑电图指数与临床神经心理学评估之间存在显著相关性。delta频率范围内的成对衍生脑对称性指数与大多数神经心理学结果相关。我们在临床环境中采用脑电图作为辅助评估是可行的。
