摘要: 创伤后应激障碍是个体经历严重应激后形成的一种焦虑障碍,对其治疗的关键是消退由创伤应激导致的条件性恐惧记忆,但目前最有效的暴露疗法并不能真正有效地抑制患者恐惧记忆的表达。对条件性恐惧的动物模型研究发现情绪性增强效应、恐惧记忆二级条件化与再巩固、内侧前额叶皮层功能不足等均能够阻碍条件性恐惧记忆的消退。针对这几个方面可以探索治疗创伤后应激障碍的相应方法

The key of treatment for this disorder is to extinct the conditioned fear memory acquired in trauma. But the most effective exposure therapy can’t repress fear memory efficiently.

According to these reasons,corresponding treatment ways can be explored and developed

Key words: conditioned fear memory, extinction, emotional enhancing effect, secondary-order conditioning, reconsolidation, medial prefrontal cortex
