Narcissistic personality disorder is a mental disorder characterized by an inflated sense of self-importance, a need for admiration, and a lack of empathy. Core symptoms include exaggerated beliefs in one's own abilities and attractiveness, a strong need for admiration, and lack of understanding of others' perspectives. While narcissists have an image of themselves as superior, their self-esteem is actually quite fragile due to feelings of insecurity. Risk factors include parenting styles involving excessive praise but lack of boundaries, and genetics may also play a role. Treatment options include cognitive behavioral therapy, family therapy, and group therapy.
