Borderline Personality Disorder (BPD) is a severe condition associated with intense emotional and behavioral responses to stressful events, impulsivity, and risk-taking behavior. It has been shown to begin in adolescence. However, very few studies have addressed the physiopathology of BPD in adolescents. In order to gather rational information for targeted care, the heterogeneity of BPD determinants needs to be disentangled. To this aim, a multimodal approach to BPD dimensional aspects is proposed.
