老年人急性脑血管疾病的脑电图特征

The characteristics of electroencephalogram on aged patients with acute brain vascular diseases

目的脑卒中病例的脑电图尽管无特异性改变,但对诊断和判断预后以及与脑肿瘤的鉴别仍有意义。文中旨在探讨老年人急性脑血管疾病中的脑电图改变特征及临床意义。方法对2009年12月至2011年12月连续109例老年急性脑血管病病例的临床及脑电图进行总结和对比分析。结果所有病例脑电图检查显示正常率为30.3%,异常率为69.7%,其中轻度异常25例,占异常例数的32.7%;中度以上异常13例,占异常例数的17.1%;局限性异常者21例,占异常例数的27.6%;弥散异常一侧优势17例,占22.4%。结论脑电图在急性脑血管疾病的早期诊断、病情评估及预后方面具有重要价值。

ObjectiveAlthough there was no specific changes in the electroencephalogram （EEG） of stroke, the meaning for the diagnosis and prognosis of stroke, and the identification with brain tumor is very significant. The aim of this study was to explore the clinical significance of EEG on aged patients with acute brain vascular diseases in this article.Methods109 cases of clinical neurology aged patients were collected from December 2009 to December 2011, and the clinical data and EEG of the patients were summarized and analyzed.ResultsThe results showed that the percentage of normal EEG was 30.3% and abnormal EEG was 69.7%, of which 25 cases had mild abnormalities with the percentage of 32.9% of the abnormal; 13 cases had moderately abnormal with the percentage of 17.1% of the abnormal; and 21 cases had limitation abnormalities with the percentage of 27.6% of the abnormal.ConclusionEEG presents significant value in the early diagnosis, pathogenetic condition assessment and the prognosis in acute cerebrovascular diseases.
