Although the manifestation of borderline personality disorder (BPD) is situated in adolescence and young adulthood, in clinical practice the diagnosis and treatment often get delayed until adulthood. Preliminary research shows good results for structured treatments in young people with BPD. Early intervention programs for BPD show promising results in improvement of the level of functioning. This case study of a fourteen-year-old girl with BPD illustrates early intervention within the program Helping Young People Early (HYPE). This case illustrates the understanding, recognition and revision of relational patterns in emotional and relational problems. In addition, the case highlights the multidisciplinary integration of psychotherapeutic, systemic theoretical and psychosocial ingredients within a multidisciplinary early intervention program for BPD.
