## Abstract

The influence of early life trauma on the emergence of borderline personality symptoms has been extensively researched. However, despite the established correlation between childhood maltreatment and borderline personality disorder (BPD), the specific types of trauma and the mediating pathways remain insufficiently mapped. While sexual abuse has received substantial attention due to its measurable clinical impact, the roles of withdrawal and emotional neglect lack early detection and intervention during childhood. Understanding the multifactorial origins of BPD is essential for developing early preventive strategies and effective therapeutic models. This review discusses how the multiple and cumulative effects of maltreatment, including omission-type maltreatment such as emotional neglect, may contribute to the development of BPD through both physical and psychological mediators. This narrative review emphasizes the necessity of recognizing invisible or under-addressed trauma types, proposing conceptual pathways, and informing trauma-informed care focused on the physical, emotional, and social safety of children and adolescents.
