Narcissistic Personality Disorder is characterized by grandiosity, need for admiration, and lack of empathy. It is caused by incorrect child rearing such as indulgence that creates entitlement or a distant father figure. There are four types of narcissists including needy, deceptive, exhibitionistic, and critical. Treatment is difficult as narcissists do not believe anything is wrong with their behavior and do not change, so the best approach is for others to shield themselves emotionally from the narcissist.
