Narcissistic Personality Disorder (NPD) is a psychological condition characterized by an excessive preoccupation with oneself, a grandiose sense of self-importance, a constant need for admiration, and a lack of empathy towards others. Individuals with NPD often have an exaggerated sense of entitlement and believe they are special or unique. This disorder falls within the Cluster B personality disorders, which also include histrionic, borderline, and antisocial personality disorders.
