摘要
观察了３０例Ｂｉｎｓｗａｎｇｅｒ病（ＢＤ）和３０例Ａｌｚｈｅｉｍｅｒ病（ＡＤ）患者的脑电地形图（ＢＥＡＭ）变化。结果发现，ＢＤ患者和ＡＤ患者的ＢＥＡＭ阳性率均高于脑电图（ＥＥＧ）。ＢＤ患者ＢＥＡＭ局灶性和阵发性改变阳性率明显高于ＡＤ患者，并且双侧脑电功率谱不对称，以额、中央、枕区θ波多见，而ＡＤ患者双侧功率谱基本对称，以额、颞、顶区δ波多见。ＢＤ患者长谷川简易智力量表分值与ＢＥＡＭ异常改变程度有显著相关性。提示ＢＥＡＭ检查对ＢＤ的鉴别诊断和病情监测具有一定意义。
The changes of BEAM in 30 patients with Binswanger disease (BD)and in controls with Alzheimer disease (AD)were observed. The results showed that the positive rate of focal and paroxysmal changes was significantly higher in BD than in AD. Relative power spectrum of BEAM showed asymmetry in bihemispheres and a remarkable θwave in the frontal,centrical and occipital areas in patients with BD,while it did nearly symmetry and prominant δwave in frontal,tempral and parietal regions in patients with AD.The value of HDS was strongly related to the abnormal changes of BEAM. These data suggested that BEAM be benificial to the differential diagnosis and surveillance of BD.
