目的分析并研究老年急性脑梗死患者脑电图异常与癫痫发作之间的关系。方法 148例老年急性脑梗死患者,对患者脑梗死部位异常的脑电图类型进行观察和记录,分析患者脑电图异常与癫痫发作的关系。结果不同发作位置癫痫异常放电的发生率分别为55.81%(24/43)、45.10%(23/51)、82.35%(14/17)、24.32%(9/37),四种不同位置癫痫异常放电发生率比较,差异均具有统计学意义(P<0.05)。痫癫迟发发作率为44.00%(22/50)明显高于早期视频脑电图检测无异常且无癫痫异常放电患者的8.22%(6/73),差异具有统计学意义(χ~2=28.1537,P<0.05)。结论临床上需要密切对老年急性脑梗死患者的脑电图进行积极检测,如发现有脑电图癫痫异常放电患者,应该在密切关注的同时予以必要的手段来预防癫痫的发作。
Objective To analyze and study the relationship between EEG abnormalities and seizures in elderly patients with acute cerebral infarction. Methods A total of 148 cases of elderly patients with acute cerebral infarction were observed and recorded the types of EEG abnormalities in patients with cerebral infarction. The relationship between EEG abnormalities and seizures was analyzed. Results The incidences of abnormal epilepsy were 55.81% (24/43), 45.10% (23/51), 82.35% (14/17) and 24.32% (9/37) respectively in different seizure locations. There were four kinds of epileptic abnormalities Discharge rate comparison, the differences were statistically significant (P <0.05). The delayed onset rate of epileptic seizure was 44.00% (22/50), which was significantly higher than 8.22% (6/73) in patients with abnormal ECG without abnormalities detected by early video electroencephalography (χ ~ 2 = 28.1537, P <0.05). Conclusions Clinically, EEG in elderly patients with acute cerebral infarction needs to be closely tested. If abnormal EEG is found in patients with EEG abnormal discharge, we should pay close attention to the necessary measures to prevent the onset of epilepsy.
