Narcissistic personality disorder (NPD) often involves reduced or a complete lack of consideration or empathy, arrogance in both thoughts and actions.
Those with narcissism could be thought of as demanding, patronizing, manipulators, and cocky and the way the disorder presents generally surfaces in every area of the individuals life.
It is a Cluster B Personality Disorder characterized by the triad of:
An inflated sense of self-importance
An excessive need for admiration
Lack of empathy toward other people
Extreme sensitivity to criticism
While many successful people can seem to have some symptoms of narcissistic disorder, those with true NPD persistently show the symptoms and don’t change over time.
NPD affects up to 6% of the general population and 50% to 75% of these are male. The age of onset of NPD is usually late childhood or early adulthood.
