Narcissistic personality disorder

Narcissistic personality disorder is a mental condition in which a person has:

  • An excessive sense of self-importance
  • An extreme preoccupation with themselves
  • A lack of empathy for others


Cause of this disorder is unknown. Early life experiences, such as particularly insensitive parenting, are thought to play a role in the development of this disorder.


A person with narcissistic personality disorder may:

  • React to criticism with rage, shame, or humiliation
  • Take advantage of other people to achieve his or her own goals
  • Have excessive feelings of self-importance
  • Exaggerate achievements and talents
  • Be preoccupied with fantasies of success, power, beauty, intelligence, or ideal love
  • Have unreasonable expectations of favorable treatment
  • Need constant attention and admiration
  • Disregard the feelings of others, and have little ability to feel empathy
  • Have obsessive self-interest
  • Pursue mainly selfish goals

Exams and tests

Narcissistic personality disorder is diagnosed based on a psychological evaluation. The health care provider will consider how long and how severe the person's symptoms are.


Talk therapy may help the person relate to other people in a more positive and compassionate way.

Outlook (Prognosis)

Outcome of treatment depends on the severity of the disorder.

Possible Complications

Complications may include:

  • Alcohol or other drug dependence
  • Relationship, work, and family problems
