脑震荡的多形式诱发电位研究

Study on multimodality evoked potentials in patients with concussion

目的 研究脑震荡患者的多形式诱发电位变化。方法 对 26例急性期脑震荡患者行视觉诱发电位 (VEP)、脑干听觉诱发电位 (BAEP)、体感诱发电位 (SEP)及事件相关电位 (ERP)检测，并与年龄、身高匹配的健康者对比。结果 VEP、 BAEP、 SEP、 ERP及 EEG异常率分别为 30.8％、 69.2％、 50％、 61.5％、 38.5％；其中有两项诱发电位异常者占 80.8％，较 EEG异常率高

Objective To observe the changes of multimodality evoded potentials (M EP) in patients with concussion .Method 26pa-tients with concussion were studied simultaneously with pattem VEP、 BAEP、 SEP and ERP. Result The abnormal ratios of VEP、 BAEP、 SEP、 ERP and EEG for concussion were 30.8％、 69.2％、 50％、 61.5％、 38.5％ .The abnormal ratios of M-EP and EEG (P<0.01).Conclusion Concussion might have brainstem damage and brain functionimpairment nad disorder of cognition function M-EP might be helpful in assessing brain function after comcussion.
