Comparing the symptom presentation similarities and differences of complex posttraumatic stress disorder and borderline personality disorder: A systematic review.

Complex posttraumatic stress disorder (CPTSD) is characterized in the by affect dysregulation, negative self-concept, and relationship impairments, symptoms also presented in borderline personality disorder (BPD). Some research shows CPTSD as a distinct disorder, others as a subgroup or a replacement for BPD. No review currently amalgamates the findings on whether CPTSD presents too similarly to BPD to be a standalone disorder.
