The concept of intergenerational transmission of trauma plays a fundamental role in psychoanalysis. While it is known that intergenerational trauma can be transmitted through attachment relationships, a new branch of genetics (epigenetics) has emerged to study the interaction between human behavior and changes in DNA expression. Therefore, psychoanalysis, which has proven to reduce the intergenerational transmission of trauma from a behavioral perspective, can play a positive role in regulating DNA changes caused by environmental stress. The present paper focuses on recent research suggesting a direct correlation between psychological trauma and DNA modifications. In particular, DNA changes caused by psychological trauma can be transmitted from generation to generation, validating the psychoanalytic concept of intergenerational transmission of trauma. This evidence not only supports the essential role psychoanalysis has in influencing human behavior, but also suggests that it affects not only the individuals who undergo it but their offspring, as well, via the epigenetic passage of DNA.
创伤的代际传递概念在精神分析中起着基础性作用。虽然已知代际创伤可通过依恋关系传递，但一个新的遗传学分支（表观遗传学）已出现，用于研究人类行为与DNA表达变化之间的相互作用。因此，已证明能从行为角度减少创伤代际传递的精神分析，可在调节由环境压力引起的DNA变化方面发挥积极作用。本文聚焦于近期研究，这些研究表明心理创伤与DNA修饰之间存在直接关联。特别是，由心理创伤引起的DNA变化可代代相传，这证实了创伤代际传递的精神分析概念。这一证据不仅支持了精神分析在影响人类行为方面的重要作用，还表明它不仅影响接受精神分析的个体，还会通过DNA的表观遗传传递影响他们的后代。
