目的：研究结核性脑膜炎（结脑）的脑电图（ＥＥＧ）与临床的关系。方法：对３６例结脑进行ＥＥＧ常规描记、腰穿脑脊液检查和脑部ＣＴ扫描。结果：ＥＥＧ异常率７２．２％；ＥＥＧ异常表现主要有三种形式：以弥漫性异常为主；弥漫性异常背景上有局灶性活动；局灶性异常。有意识障碍者ＥＥＧ异常率为１００％，无意识障碍者ＥＥＧ异常率为６０％（Ｐ＜０．０５）；疾病恶化者ＥＥＧ异常率为１００％，疾病好转或治愈者ＥＥＧ异常率为６６．１％（Ｐ＜０．０５），ＥＥＧ异常与意识障碍及预后有平行关系。结论：ＥＥＧ对结脑的早期诊断、判断病情、病重程度及疗效有益，对预后的评估有一定的帮助。
Objective: To study the relationship between EEG and clinical features of tuberculous meningitis (tuberculous meningitis). Methods: 36 cases of tuberculous brain EEG routine tracings, lumbar puncture cerebrospinal fluid and brain CT scan. Results: The abnormal rate of EEG was 72.2%. There were three main manifestations of EEG abnormalities: diffuse abnormality; focal abnormality on diffuse background; focal abnormality. The EEG abnormality rate was 100% in the conscious group, and 60% in the unconscious group (P <0.05). The EEG abnormality rate in the worsening group was 100%, and the abnormal EEG rate in the group with disease improvement or cure was 66.1% (P <0.05). There was a parallel relationship between EEG abnormalities and disturbance of consciousness and prognosis. Conclusion: EEG is helpful to the early diagnosis of tuberculous meningitis, judging the severity, severity and curative effect of the brain, and evaluating the prognosis.
