摘要
报告经ＣＴ、磁共振成像（ＭＲＩ）证实的６８例脑基底节区梗塞患者的脑电地形图（ＢＥＡＭ），并与５０例正常对照组的ＢＥＡＭ作对照，结果梗塞组ＢＥＡＭ３６例（５３％）异常：其中３３例以θ波频带能量增高为主要表现（２９例位于大脑前半部，４例位于大脑后半部）；３例（８％）为δ波频带能量增高，均在后半部。对照组ＢＥＡＭ异常４例（８％），表现在额、颞区θ波频带能量稍有增高。脑梗塞组与正常对照组比较，ＢＥＡＭ异常率有明显差异。
The BEAM of 68 cases with basal ganglion infarction (BCI) confirmed by CT and MRI were reported and was compared with that of 50 normal subjects. Abnormal BEAM was found in 36 cases (53%).in whom 33 showed mainly an increase in energy of wave frequency band(29 in the anterior cerebral hemispbere,4 in the posterior),and 3 showed an increase in energy of δ wave frequency band in the posterior hemisphere. Abnormal BEAM in the control group was observed in 4(8%) with a slight increase in energy of 6 wave frequency band in the frontal and temporal regions. Mark difference of abnormal BEAM was noted between BCI and control groups.
