In this video, the speaker explored the psychodynamic relationship between borderline personality disorder (BPD) and narcissistic personality disorder (NPD), proposing that BPD is a mirror image of narcissism, with distinct but parallel mechanisms of control and anxiety relating to presence and absence in relationships. The discussion included differences in how both disorders manage intimacy, separation, and devaluation, as well as their avoidant and schizoid phases, contrasted with avoidant personality disorder (AvPD), which shares some symptoms but differs fundamentally in causes and behavioral responses. The speaker also illustrated avoidant personality disorder with a clinical example, emphasizing its common misdiagnosis due to overlapping traits with BPD and NPD despite distinct psychodynamic foundations.
