| 目的：探讨不同部位脑梗死导致血管性痴呆的脑电图表现差异，为血管性痴呆的诊断分类提供客观依据。方法：80 例诊断血
管性痴呆的患者根据影像学表现分为多灶梗死后痴呆和关键部位梗死后痴呆。入选患者均于饱餐后2 小时给予常规18 导脑电
图检查，记录时间为30 分钟以上。结果：①多灶梗死后痴呆多表现为琢节律减慢，6-8Hz为主；波幅低，以20-25Uv 为主，α波频
率调节差、节律不规则。低波幅兹波出现者27 例，占71.1%，出现于各导联，出现δ波者17 例，占44.7%。②关键部位梗死后痴呆
的患者中，正常为6 例，占13%。异常者39 例，占87%。EEG 改变主要表现为α指数减少，节律以7-9Hz 为主的患者28 例，占
71.8%。低波幅兹波出现者17 例，以前额为主，占43.6%。39 例患者未出现δ波。结论：不同部位梗死后血管性痴呆的脑电图表现
不尽相同，可以为血管性痴呆的分类诊断提供客观依据。 |

| Objective:To explore the EEG differences about the vascular dementia after cerebral infarction in different locations in
order to provide a basis for the clinical diagnosis.Methods:80 patients with vascular dementia who were diagnosed in our hospital were
divided into multiple focal infarction dementia group and key parts after infarction dementia group,. All the patients were treated with 18
guide routine EEG examination after the meal for two hours, and recorded time for more than 30 minutes.Results:(1) Multiple focal
infarction dementia characterized by alpha rhythm slow and 6-8 Hz; Volatility was low with 20-25 Uv, alpha frequency and irregular
rhythmadjustment. Low amplitude theta in 27 cases, accounting for 71.1%, in the lead, in the delta of 17 cases, accounting for 44.7%. (2)
Key parts after infarction dementia patients, normal for 6 cases, accounting for 13%. Abnormal in 39, accounting for 87%. EEG changes
mainly for alpha index decreased, rhythm is given priority to with 7-9 Hz patients 28 cases, accounting for 71.8%. Low amplitude theta
wave in 17 cases, give priority to with his forehead, accounting for 43.6%. 39 patients does not appear the delta wave.Conclusion:EEG
performance of different types of infarction dementia is not the same, can provide objective basis for the classification of vascular
dementia diagnosis. |
