Commentary: Bringing together lived experience, clinical and research expertise – a commentary on the May 2022 debate (should CAMH professionals be diagnosing personality disorder in adolescence?)

Background There is a wealth of evidence to suggest that the Borderline Personality Disorder (BPD, or similar Emotionally Unstable Personality Disorder, EUPD) construct is harmful.

Conclusions We ask readers to consider these concerns, perspectives and ideas
