Narcissistic personality disorder

Narcissistic personality disorder (NPD) is a personality disorder, characterized by exaggerated feelings of self-importance, excessive need for admiration, and lack of empathy for others. People with the disorder often come across as arrogant, callous, and envious, tend to be exploitative in their interpersonal relationships, and can be excessively preoccupied with personal adequacy, power, prestige and vanity. As a personality disorder, those with NPD generally have poor insight into their condition and may not acknowledge that their behavior causes problems for others or themselves.
