Narcissistic personality disorder (NPD) is 1 of the 4 cluster B personality disorders, which also include antisocial personality disorder (ASPD), borderline personality disorder (BPD), and histrionic personality disorder (HPD). Whereas NPD is a distinct entity, it shares many similarities with the other cluster B disorders, which can be concomitantly diagnosed if the appropriate diagnostic criteria are met. It is therefore important to be aware of the salient differences among the cluster B personality disorders. [1]
