Narcissistic personality disorder
A pervasive pattern of grandiosity (in fantasy or behaviour), need for admiration and lack of empathy, causing impairment in relationships and work. It includes grandiose and vulnerable presentations, often in the same person at different moments. McWilliams places the narcissistic style at healthy, neurotic and borderline levels; most people with the disorder sit at the borderline level of organisation.
What drives it
Holds together a self that would otherwise feel empty, inadequate or worthless by maintaining a grandiose self-image and drawing admiration from others. Kohut saw it as arrested development of normal needs for mirroring; Kernberg as a pathological grandiose self built to defend against envy and rage.
How it shows
Work
Inflated self-presentation, credit-taking, belittling of peers, rage or sulking at criticism, exploitation of juniors, little curiosity about others' perspectives, a trail of burnt relationships, idealised mentors who are later devalued. Often impressive in the short term and costly over time.
Relationships
Love bombing, followed by devaluation once the partner is no longer a source of admiration, little empathy for the partner's distress, affairs, contempt when the partner has needs, rage at being left.
Self
People with NPD rarely recognise it; when they do, it is often through depression or emptiness after a loss of status, a feeling that others are either impressive or worthless, and boredom in ordinary intimacy.
What tells it apart
Grandiose narcissism: Grandiose narcissism is a trait common in successful people; NPD requires pervasive impairment and lack of empathy. Look for the wreckage: lost relationships, repeated conflicts, inability to sustain intimacy.
Hubris syndrome: Hubris syndrome develops after years of power in someone without a prior narcissistic pattern, and often fades when power is lost; NPD predates success and persists.
Antisocial personality: Both exploit; the narcissist cares deeply about how they are seen and is shamed by exposure, while the antisocial person is indifferent to reputation beyond its usefulness.
A test
Look for the full cycle over time: idealisation, use, devaluation and discard, repeated across multiple people, with no capacity to see their own part. From outside you can name the pattern; a diagnosis needs a clinician, a full history and evidence of impairment across settings.
Questions to carry
- Over the years, how do this person’s relationships tend to begin, and how do they tend to end?
- Which person did I once admire and later dismiss, and what changed between those two moments?
How strong the research is
moderate. Retained in the DSM-5-TR Alternative Model; DSM criteria capture grandiose features well and vulnerable features poorly, and prevalence estimates vary widely.
