Comorbidity between Post-Traumatic Stress Disorder and Borderline Personality Disorder: A Review
Abstract
Background: Traditionally, the presence of post-traumatic stress disorder (PTSD) in subjects diagnosed with borderline personality disorder (BPD) has been the object of scant empirical research. The clarification of issues related to the different areas of study for this comorbidity is not only significant from a theoretical point of view but also relevant for clinical practice. The aim of this review is to describe the main theoretical findings and research conclusions about the comorbidity between PTSD and BPD. Methods: A literature review was carried out via PubMed and PsycINFO for the period between 1990 and September 2013. The descriptors used were ‘post-traumatic stress disorder', ‘borderline personality disorder', ‘PTSD', ‘complex PTSD' and ‘BPD'. Results: Epidemiological studies show that the risk of PTSD among BPD subjects is not regularly higher than in subjects with other personality disorders. Furthermore, there is no conclusive evidence about the main aetiopathogenic mechanism of this comorbidity, either of one disorder being a risk factor for the other one or of common underlying variables. Concerning comparative studies, several studies with PTSD-BPD subjects have found a higher severity of psychopathology and psychosocial impairment than in BPD subjects. With regard to nosological status, the main focus of controversy is the validation of ‘complex PTSD', a clinical entity which may comprise a subgroup of PTSD-BPD subjects. With regard to treatment, there are preliminary evidences for the efficient treatment of psychopathology in both PTSD and BPD. Conclusions: These findings are remarkable for furthering the understanding of the link between PTSD and BPD and their implications for treatment. The results of this review are discussed, including methodological constraints that hinder external validity and consistency of referred findings.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
