My subdued ego: A psychodynamic case study of borderline personality disorder following relational trauma

Recent advances in the conceptualisation of borderline personality disorder (BPD) have highlighted the role of relational trauma as central to the onset of the disorder, whilst observing deficits in the structure of the self-concept as a result of developmental adversity. Understanding borderline states within a psychiatric framework alone has attracted significant criticism due to the lack of the medical model’s explanatory properties, which fail to account for the complexity and variation of borderline symptomatology. A reliance on psychodynamic formulation instead, can provide an aetiological framework where BPD can be understood as a disorder of the sense of self, originating in the client’s relational matrix. The purpose of the current paper is to discuss a borderline case study with a focus on formulation rather than diagnosis, in an attempt to shed light on the relational and unconscious processes underpinning the disorder and thus inform treatment interventions.
