narcissism (närsĭsˈĭzəm) [key], Freudian term, drawn from the Greek myth of Narcissus, indicating an exclusive self-absorption. In psychoanalysis, narcissism is considered a normal stage in the development of children. It is known as secondary narcissism when it occurs after puberty, and is said to indicate a libidinal energy directed exclusively toward oneself. A degree of narcissism is considered normal, where an individual has a healthy self-regard and realistic aspirations. The condition becomes pathological, and diagnosable as a personality disorder, when it significantly impairs social functioning. An individual with narcissistic personality disorder tends to harbor an exaggerated sense of his own self-importance and uniqueness. He is often excessively occupied with fantasies about his own attributes and potential for success, and usually depends upon others for reinforcement of his self-image. A narcissist tends to have difficulties maintaining healthy interpersonal relationships, stemming largely from a lack of empathy and a propensity for taking advantage of others in the interest of self-aggrandizement. It is often found in combination with antisocial personality disorder.
