Borderline personality disorder vs Histrionic and narcissistic personality disorders
How to tell Borderline personality disorder and Histrionic and narcissistic personality disorders apart when a board question makes them look alike.
Borderline is instability and abandonment/self-harm; histrionic is attention-seeking theatrical emotion; narcissistic is grandiosity and low empathy.
Side by side
Borderline personality disorder has unstable relationships, self-image, affect, impulsivity, fear of abandonment, recurrent self-harm, emptiness, anger, and transient stress-related paranoia or dissociation.
Histrionic personality disorder has attention-seeking theatricality and shallow shifting emotion; narcissistic personality disorder has grandiosity, need for admiration, and lack of empathy.
Cluster B disorders are separated by the central interpersonal pattern: abandonment-driven instability versus attention seeking versus grandiosity.
Histrionic behavior seeks attention through dramatic/emotional style; narcissistic behavior protects grandiose self-importance and entitlement.
Splitting, frantic efforts to avoid abandonment, impulsive self-damaging behavior, and self-injury support borderline personality disorder.
Suggestibility and dramatic attention seeking support histrionic; entitlement, envy, exploitation, and fragile self-esteem support narcissistic.
The trap
All three are Cluster B personality disorders (dramatic, emotional, erratic) and they share dysregulated relationships, so the motive and core defect decide. BORDERLINE personality disorder: chronic feelings of emptiness, intense fear of ABANDONMENT, unstable relationships that swing between idealization and devaluation (splitting), recurrent suicidal threats and self-harm cutting, identity disturbance, transient stress-related paranoia or dissociation; treat with dialectical behavior therapy. HISTRIONIC personality disorder: excessive emotionality and ATTENTION-SEEKING, inappropriate sexually provocative behavior, theatrical and exaggerated emotion, suggestible, considers relationships more intimate than they are. NARCISSISTIC personality disorder: GRANDIOSITY, need for admiration, lack of empathy, sense of entitlement, exploitative interpersonal relationships, fragile self-esteem that reacts to criticism with rage or devaluation. Antisocial (the fourth Cluster B) is disregard for and violation of others' rights with criminality.
The repair move
For Cluster B, identify the repeated interpersonal theme rather than reacting to drama alone.
