From Wikipedia, the free encyclopedia
Narcissistic personality disorder (NPD) is a personality disorder…People with narcissistic personality disorder are characterized by their persistent grandiosity, excessive need for admiration, and a disdain and lack of empathy and for others. These individuals often display arrogance, a sense of superiority, and power-seeking behaviors. Narcissistic personality disorder is different than having a strong sense of self-confidence. This is because people with NPD typically value themselves over others to the extent that they disregard the feelings and wishes of others and expect to be treated as superior regardless of their actual status or achievements. In addition, people with NPD may exhibit fragile egos, an inability to tolerate criticism, and a tendency to belittle others in an attempt to validate their own superiority.
