Borderline personality: revisiting its classification as a neurodevelopmental disorder.

Area of Science:

• Psychiatry
• Neurodevelopmental Disorders
• Clinical Psychology

Background:

• Borderline personality disorder (BPD) is traditionally classified as a personality disorder.
• Emerging research suggests a potential neurodevelopmental origin for BPD.
• A neurodevelopmental perspective offers new avenues for understanding and managing BPD.

Purpose of the Study:

• To evaluate borderline personality disorder against established criteria for neurodevelopmental disorders.
• To explore the potential of classifying BPD as a late-onset neurodevelopmental disorder.
• To facilitate earlier identification and intervention for individuals with BPD.

Main Methods:

• Systematic review of recent studies on BPD and neurodevelopment.
• Identification and application of six diagnostic criteria for neurodevelopmental disorders.
• Analysis of how BPD aligns with these neurodevelopmental criteria.

Main Results:

• Borderline personality disorder exhibits characteristics aligning with neurodevelopmental disorder criteria.
• Evidence supports the conceptualization of BPD as a disorder with childhood precursors and adolescent manifestation.
• The disorder appears to manifest fully during adolescence, a key period of brain development.

Conclusions:

• Borderline personality disorder may be re-conceptualized as a late-onset neurodevelopmental disorder.
• This neurodevelopmental framework aids in understanding BPD's presentation in adolescence.
• Adopting this perspective can enhance early detection and treatment of BPD.
