军人创伤后应激障碍与适应障碍的视觉和听觉诱发电位研究

目的 探讨军人创伤后应激障碍和适应障碍的视觉诱发电位和听觉诱发电位的特征。方法 对33例创伤后应激障碍患者和34例适应障碍患者及30名健康军人(对照组),应用Nicolet Bravo型脑电生理仪及光、声刺激,完成视觉诱发电位和听觉诱发电位检测。结果 应激障碍组和适应障碍组Cz脑区视觉诱发电位／P2波幅较对照组为低,应激障碍组Pz脑区视觉诱发电位／P3波幅分别较对照组和适应障碍组为低;应激障碍组Oz脑区听觉诱发电位／P3潜伏期较对照组延迟,Cz脑区听觉诱发电位／P2波幅分别较对照组和适应障碍组为低,Cz脑区听觉诱发电位／P3波幅分别较对照组和适应障碍组为高。结论 应激障碍和适应障碍的诱发电位有一定的特征,值得进一步随访观察。

The clinical applications of visual and auditory evoked potentials in soldier''''s patients with post-traumatic stress disorder and adjustment disorder

Objective To explore the variant traits of visual (VEP) and auditory evoked potentials (AEP) in soldier's patients with post-traumatic stress disorder (PTSD) and adjustment disorder (AD). Methods The VEP and AEP were conducted with American Nicolet Bravo Instrument in 33 patients with PTSD, 34 ones with AD and 30 healthy soldiers (as controls). Results P 2 amplitudes of Cz VEP in the PTSD and AD were lower than those in the controls, and P 3 of Pz VEP in PTSD lower than those in both AD and controls; compared with the AD and controls, P 3 latencies of O z AEP were longer, P 2 amplitudes of C z AEP lower and P 3 higher in the PTSD. Conclusion The characteristics of evoked potentials of PTSD and AD patients deserve further follow-ups.
