Trauma and dissociation: implications for borderline personality disorder.

Area of Science:

• Psychiatry
• Psychology
• Neuroscience

Background:

• Psychological trauma significantly impairs emotion regulation and can trigger dissociative processes.
• Dissociation involves symptoms like depersonalization, derealization, and altered self-perception.
• Dissociative symptoms are prevalent in up to two-thirds of patients diagnosed with borderline personality disorder (BPD).

Purpose of the Study:

• To review the complex relationship between psychological trauma, dissociation, and borderline personality disorder (BPD).
• To illustrate the diverse forms of emotional dysregulation associated with traumatic dissociation in BPD.
• To underscore the clinical significance of these phenomena for BPD patients.

Main Methods:

• Literature review synthesizing research on trauma, dissociation, and BPD.
• Examination of neurobiological findings related to traumatic dissociation.
• Analysis of emotional dysregulation patterns in BPD.

Main Results:

• Traumatic dissociation is linked to heterogeneous posttraumatic stress symptoms.
• Different types of emotional dysregulation emerge over time in individuals with a history of trauma.
• Dissociation is a common feature in BPD, contributing to emotional dysregulation.

Conclusions:

• Trauma, dissociation, and BPD are interconnected, with dissociation serving as a coping mechanism.
• Understanding the spectrum of dissociative symptoms is crucial for diagnosing and treating BPD.
• This review highlights the clinical relevance of addressing traumatic dissociation in BPD management.
