应用NDC -脑电地形图仪检查和分析了 76 5例头痛患者的脑地形图和脑电功率谱 ,结果发现脑地形图阳性率为 6 6 .3 % ,主要表现为α频带功率前移和枕区功率值左右不对称 ,且脑电地形图阳性率的异常程度与头痛症状的轻重呈相关性 ;随着治疗后临床症状的好转及消失而逐渐转阴性 ,表明脑电地形图是检查头痛症状的一种行之有效的方法 The topography and EEG spectra of 765 patients with headache were examined and analyzed by NDC-EEG. The positive rate of brain topography was 66.3%, which was mainly manifested by the α-band power forward and pillow Regional power value is asymmetric, and the abnormality of positive rate of EEG is correlated with the severity of headache symptoms. With the improvement and disappearance of clinical symptoms after treatment, it gradually turns negative, indicating that the EEG topographic examination is a symptom of headache An effective method
