Background:
Epigenetic research has pointed to that the interaction between genetics and environmental factors may play a role in making some individuals more vulnerable than others.
Aim:
The aim of this article was to present a broad perspective on the current state of knowledge in a relatively new and complex field of "attachment and epigenetic processes."
Method:
We conducted a scoping review based on a systematic literature search in PsycINFO, PubMed, and Embase databases for relevant abstracts using the terms attachment and epigenet*.
Results:
In total, 11 studies were included. Research predating 2009 and animal studies were excluded in order to review the current state of research in humans.
Conclusion:
Overall, there seems to be a consistency in the literature, pointing to a link between early childhood adversity, attachment processes, and epigenetic changes. However, research in human subjects is still limited.
