边缘性人格障碍与焦虑症的诱发电位比较

目的 探讨边缘性人格障碍（ＢＰＤ）和焦虑症（ＡＮ）在诱发电位中的特点。方法 收集２７例ＢＰＤ组，３４例ＡＮ及５２名正常成人对照组（ＮＣ），应用美国仪器以及光、声触刺激，完成视觉诱发电位（ＶＥＰ）、听觉诱发电位（ＡＥＰ）和体感诱发电位（要与ＮＣ相比，ＢＰＤ组潜伏期ＶＥＰ／Ｐ１、Ｐ２，ＡＥＰ／Ｐ１，Ｎ２前移，波幅ＶＥＰ／Ｎ１－Ｐ２，Ｐ３，ＡＥＰ／Ｐ３，ＳＥＰ／Ｐ３，Ｐ３增高但波幅ＶＥＰ／Ｐ２－Ｎ２、Ｐ

A comparative study of borderline personality disorder and anxiety neurosis using evoked potentials

Objective In order to investigate the characteristics of evoked potentials of patients with borderline personality disorder (BPD) and anxiety neurosis (AN), this study was made Methods There were 27 BPD patients, 34 AN patients and 52 normal controls included into this study Visual evoked potentials(VEP), auditory evoked potentials(AEP) and somatosensory evoked potentials(SEP) were recorded from every subject, using an American Nicolet CA 1000 instrument Results Compared with the normal controls, BPD group showed shortened latencies (VEP/P 1, P 2, AEP/P 1, N 2), increased amplitudes (VEP/N 1 P 2, P 3, AEP/P 3, SEP/P 2, P 3) and decreased amplitudes (VEP/P 2 N 2, AEP/P 2); AN group also presented shortened latencies (VEP/P 1, P 3, AEP/N 2) and decreased amplitudes (VEP/P 2 N 2, P 2, AEP/P 2, SEP/P 2 N 2, P 3) A significant difference of evoked potentials between BPD group and AN group was found with the latency of VEP/P 2, the amplitude of VEP/N 1 P 2, AEP/P 3 and SEP/P 2 N 2, P 2, P 3 BPD patients showed shorter latency and higher amplitude than AN group Conclusion The characteristics of evoked potentials of BPD and AN patients deserve more intensive studying
