DSM-IV-TRspecifies nine diagnostic criteria for NPD. For the clinician to make the diagnosis, an individual must fit five or more of the following descriptions:[I]

*He or she lives in a dream world of exceptional success, power, beauty, genius, or "perfect" love.
*He or she thinks of him- or herself as "special" or privileged, and that he or she can only be understood by other special or high-status people.
*He or she demands excessive amounts of praise or admiration from others.
*He or she feels entitled to automatic deference, compliance, or favorable treatment from others.
*He or she is exploitative towards others and takes advantage of them.
*He or she lacks empathy and does not recognize or identify with others' feelings.
*He or she is frequently envious of others or thinks that they are envious of him or her.
