通过对2518例癫痫脑电图变化分析,临床确诊与未确诊癫痫脑电图异常率之间存在着显著性差异,提示脑电图异常率与临床诊断准确性有密切关系。有25.45%癫痫患者脑电图结论正常,提示不能单凭脑电图表现去诊断癫痫。通过统计,无论是原发性癫痫的各种类型,还是症状性癫痫的不同原因,脑电图异常率之间都存在着非常显著性差异;原发性与继发性癫痫脑电图异常率之间却无显著性差异。对癫痫患者,如果脑电图改变虽属异常,却未见到棘波、尖波,则应结合临床考虑可能为症状性癫痫。
Through the analysis of 2518 epilepsy EEG changes, there is a significant difference between the abnormal rate of EEG diagnosed and unconfirmed epilepsy, suggesting that the abnormal rate of EEG is closely related to the accuracy of clinical diagnosis. 25.45% of epilepsy patients with normal EEG conclusions, suggesting that the diagnosis of epilepsy can not be based solely on EEG performance. Through statistics, whether it is various types of primary epilepsy or symptomatic epilepsy for different reasons, there is a very significant difference between the abnormal rate of EEG; primary and secondary epilepsy EEG abnormal rate There was no significant difference between. For epilepsy patients, although the EEG changes are abnormal, but did not see spikes, sharp waves, it should be combined with clinical considerations may be symptomatic epilepsy.
