"The assessment and treatment of personality disorders in youth has received increased research attention in the last 10-15 years. These advances have been reflected in the legitimization of adolescent personality disorder diagnosis in psychiatric nomenclature, and in national treatment guidelines around the world. Meanwhile, it seems that scientific evidence and national practice guidelines are yet to penetrate routine clinical care. We are therefore delighted to create a section on Developmental Aspects of Personality Disorder in youth to promote research into detection, treatment and support of borderline personality disorder in young people."
