Sam Vaknin argued that many personality disorders — especially Cluster B (narcissistic, borderline, histrionic, antisocial) — reflect a single underlying disorder characterized by confusion between internal and external objects, with individuals transitioning between overt, collapsed, and covert states driven by narcissistic gaps and mortification. He described covert, collapsed, and overt presentations and outlined five covert narcissist solutions (delusional narrative, antisocial, paranoid/schizoid, paranoid-aggressive/explosive, masochistic/avoidant), extending similar state models to borderline, histrionic, and antisocial presentations. He concluded that diagnostic categories are overly fragmented and advocated for a parsimonious, dynamic model unifying these disorders while directing viewers to detailed videos and literature for deeper study.
