Narcissistic Personality Disorder

Diagnostic criteria
At least five of the following are necessary for a diagnosis (as with many DSM diagnoses, they must form a pervasive pattern; for example, a person who shows these criteria only in one or two relationships or situations would not properly be diagnosed with NPD):

-has a grandiose sense of self-importance
-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 other special people
-requires excessive admiration
-strong sense of entitlement
-takes advantage of others to achieve his or her own ends
-lacks empathy
-is often envious or believes others are envious of him or her
-arrogant behavior
