Electroencephalography is a sensitive indicator for measuring brain condition, and can reflect early changes in brain function and severity of cerebral ischemia. However, it is not yet known whether electroencephalography can predict development of post-cerebral infarction depression. A total of 321 patients with ischemic stroke underwent electroencephalography and Hamilton Depression Rating Scale assessment to analyze the relationship between electroencephalography and post-cerebral infarction depression. Our results show that electroencephalograms of ischemic stroke patients with depression exhibit low-amplitude alpha activity and slow theta activity. In contrast, electroencephalograms of ischemic stroke patients without depression show fast beta activity and slow delta activity. These findings confirm that low-amplitude alpha activity and slow theta activity can be considered as independent predictors for post-cerebral infarction depression.
脑电图是测量脑部状况的敏感指标，能够反映脑功能的早期变化以及脑缺血的严重程度。然而，脑电图是否能够预测脑梗死后抑郁症的发生尚不清楚。共有321例缺血性脑卒中患者接受了脑电图检查和汉密尔顿抑郁量表评估，以分析脑电图与脑梗死后抑郁症之间的关系。我们的结果显示，伴有抑郁症的缺血性脑卒中患者的脑电图表现为低波幅α活动和慢θ活动。相比之下，无抑郁症的缺血性脑卒中患者的脑电图显示快β活动和慢δ活动。这些发现证实，低波幅α活动和慢θ活动可被视为脑梗死后抑郁症的独立预测指标。
