Symptoms of Narcissistic Personality Disorder
In order for a person to be diagnosed with narcissistic personality disorder (NPD) they must meet five or more of the following symptoms:
- Has a grandiose sense of self-importance (e.g., exaggerates achievements and talents, expects to be recognized as superior without commensurate achievements)
- Is preoccupied with fantasies of unlimited success, power, brilliance, beauty, or ideal love
- Believes that he or she is “special” and unique and can only be understood by, or should associate with, other special or high-status people (or institutions)
- Requires excessive admiration
- Has a very strong sense of entitlement, e.g., unreasonable expectations of especially favorable treatment or automatic compliance with his or her expectations
- Is exploitative of others, e.g., takes advantage of others to achieve his or her own ends
- Lacks empathy, e.g., is unwilling to recognize or identify with the feelings and needs of others
- Is often envious of others or believes that others are envious of him or her
- Regularly shows arrogant, haughty behaviors or attitudes
Because personality disorders describe long-standing and enduring patterns of behavior, they are most often diagnosed in adulthood. It is uncommon for them to be diagnosed in childhood or adolescence, because a child or teen is under constant development, personality changes and maturation. However, if it is diagnosed in a child or teen, the features must have been present for at least 1 year.
Narcissistic personality disorder is more prevalent in males than females, and is thought to occur in up to 6.2 percent of the general population.
Like most personality disorders, narcissistic personality disorder typically will decrease in intensity with age, with many people experiencing few of the most extreme symptoms by the time they are in the 40s or 50s.
