Narcissistic personality disorder

The cause of this disorder is unknown. Early life experiences, such as insensitive parenting, are thought to play a role in developing this disorder.

A person with this 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

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

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

The outcome of treatment depends on the severity of the disorder and how willing the person is to change.

Complications may include:

• Alcohol or prescribed medicine overuse
• Illegal drug use
• Mood and anxiety disorders
• Relationship, work, and family problems
