'People with narcissistic personality disorder (NPD) are characterized by the personality traits of persistent grandiosity, an excessive need for admiration, and a personal disdain and lack of empathy for other people.[7][8] As such, the person with NPD usually displays arrogance and a distorted sense of personal superiority, and seeks to establish abusive power and control over others.... people with NPD typically value themselves over others, to the extent of openly disregarding the wishes and feelings of anyone else, and expect to be treated as superior, regardless of their actual status or achievements.[7][10] Socially, the person with narcissistic personality disorder usually exhibits a fragile ego (self-concept), intolerance of criticism, and a tendency to belittle other people, in order to validate their own superiority.'
