Personality Disorders Often Comorbid with ASPD and NPD: BPD, HPD, DPD

Cluster B & C Comorbidities

Antisocial (ASPD) and Narcissistic (NPD) Personality Disorders frequently co-occur with:

Borderline PD (BPD)

• Emotional dysregulation, frantic abandonment avoidance, unstable self-image/relationships, self-harm, impulsivity.

Histrionic PD (HPD)

• Excessive emotionality, attention-seeking, seductive behavior, shallow emotions, impressionistic speech.

Dependent PD (DPD)

• Submissive, clinging, fear of separation, difficulty deciding alone, urgently seeks new relationships when one ends.

Clinical Note

Comorbidity complicates diagnosis and treatment. Dialectical Behavior Therapy (DBT), schema therapy, and mentalization-based treatment show efficacy for Cluster B traits. Long-term psychotherapy is mainstay; medications target comorbid symptoms (depression, anxiety, impulsivity).
