Borderline personality disorder begins in adolescence, however, its diagnosis is subject to some controversy and tends to be underdiagnosed. Stigma associated with its diagnosis, comorbidity with other axis I disorders or the changeable sense of identity during adolescence are some of the elements that obscure the diagnosis. Increasingly, recent studies have shown the utility of prevention programs as well as instituting early intervention in adolescents, with very hopeful outcomes.

The aim of this study is to review the benefits derived from early prevention and intervention programs in adolescents with borderline symptoms from a cognitive analytic approach.

A systematic review for scientific articles extracted from research databases including Dialnet, EBSCO, Pubmed, Unika and Scholar Google was conducted. Other high-impact studies in the field were also included.

Evidence reported by reviewed articles supports Cognitive analytical therapy as one of the most successful approaches, the same as Mentalization based therapy, in the treatment of Borderline personality disorder. From this approach, prevention and early intervention have shown their effectiveness in reducing borderline symptoms and risk factors besides they contribute to interpersonal functioning improvement.

Prevention and early intervention constitute the main pillars to prevent the potential development of Borderline personality disorder or its evolution in more complex and irreversible forms. But this intervention must be carried not only in young already diagnosed, but also in those who are on the diagnostic threshold, presenting risk factors for further development.
