| 摘 要： | 目的 探讨焦虑性神经症患者关联性负变 (CNV)的特点。方法 采用光和声成对刺激以及反应时间技术 ,对 2 4例焦虑性神经症患者和 2 2名正常成人的CNV进行对照研究。结果 焦虑性神经症组波形不规则 ,CNV -Ⅱ型 (延迟型 )尤甚。与正常对照组比较 ,焦虑性神经症患者CNV潜伏期A点延迟 (P <0 .0 5 ) ,波幅B降低 (P <0 .0 5 )。结论 焦虑性神经症CNV变化诸特点值得进一步随访

| Abstract: | Objective To investigate the characteristics of CNV in patients with anxiety neurosis (AN). Methods CNV was evoked in 24 AN patients and 22 normal controls (NC), by flash (S1) - click (S2) paradigm. Results AN patients presented irregular CNV waveform, especially the CNV- type II. Compared with NC group, the AN group showed prolonged A latency (P<0.05) and decreased B amplitude (P<0.05). Conclusion The characteristics of CNV of AN patients deserve further follow up study. |
