创伤后心理复原的生理机制

Progress in Researches on Resilience at Biological Level after Traumatic Event

心理复原是个体在经历对生命具有威胁的事件或严重的创伤后仍然能回复到良好适应状况的现象。对心理复原生理机制的研究存在两种研究取向:或从个人能力的角度,或从发展结果的角度。创伤记忆的抑制、大脑的可塑性、神经生物的调节以及基因、气质、情绪调节、认知过程、早期经验等保护因子的影响机制是研究的主要内容。文章最后对今后的研究进行了展望。

Resilience refers to the phenomenon that a person has the achievement of positive adaptation within the context of significant adversity or trauma. There has been a personal ability-based approach and a developmental result-based approach to identify the brain and neurobiological evidence for resilience. The studies of resilient mechanism at biological level mainly focus on inhibition of traumatic memory, brain plasticity, regulation of neurobiology and effect from protective factors including gene, temperament, emotion regulation, cognitive process, and early experience. Finally, the future research trends in the relevant areas were discussed.
