외상후 성장의 개념과 신경생물학

초록

Stress and trauma research has traditionally focused on negative sequelae of adversity. Recently, research has begun to focuson positive outcomes, specifically post-traumatic growth (PTG) - “positive change experienced as a result of the struggle withtrauma” - which emphasizes the transformative potential of one’s experiences with highly stressful events and circumstances. This article describes the concept of PTG at three different perspectives. In addition we reviewed the neurobiological factorsand mechanism of PTG. It has shown that PTG is mediated by adaptive changes in several neural circuits involving numerousneurotransmitter and molecular pathways. Much more study is required to achieve a deeper understanding the biologicaland psychological underpinnings of PTG, as well as the interactions between these factors. After all, the clinical phenomenologyof PTG is very important for mental growth after trauma. The findings of this article provide further directions for researchand clinical implication of PTG.
