脑卒中认知障碍患者治疗前后的脑电特征

目的 分析卒中后认知障碍(PSCI)患者治疗前后的脑电图变化。方法 2018年10月至2019年4月,12例PSCI患者在完成常规认知训练和重复经颅磁刺激治疗6周前后,采用简易精神状态检查、蒙特利尔认知评估量表和改良Barthel指数进行评定,闭眼静息态下采集脑电图。结果 治疗后,患者各项评分均明显改善(|t| > 3.507, P < 0.01)。α波绝对功率和相对功率增高(| t| > 2.522, P < 0.05),脑对称指数和DTABR降低( t > 2.435, P < 0.05)。 结论 PSCI患者脑电图随认知功能恢复发生相应改变,可进一步研究脑电图与认知功能的关系。

Electroencephalogram for Patients with Post-stroke Cognitive Impairment before and after Treatment

Objective To analyze the changes of electroencephalogram (EEG) before and after treatment in patients with post-stroke cognitive impairment (PSCI). Methods From October, 2018 to April, 2019, twelve PSCI patients received cognitive training and repetitive transcranial magnetic stimulation for six weeks. They were assessed with Mini-Mental State Examination, Montreal Cognitive Assessment and modified Barthel Index before and after treatment, while their closed-eye resting EEG were collected. Results The scores of all the assessments improved after treatment (|t| > 3.507, P < 0.01); while alpha absolute power and alpha relative power increased (| t| > 2.522, P < 0.05), and brain symmetry index and DTABR decreased ( t > 2.435, P < 0.05). Conclusion The characteristics of EEG of PSCI patients changes with the recovery of cognitive function. Further research is needed about the relationship between EEG and cognitive function.
