NPD manifests by young adulthood (early to middle 20s) and may worsen in middle or old age as a consequence of the onset of physical infirmities or declining physical attractiveness. (In addition to feeling intellectually and socially superior to others, people who are narcissistic are often quite vain regarding their physical appearance.) Narcissistic traits can be exhibited by typical adolescents who are unlikely to go on to develop NPD.

NPD is more commonly found in males than in females; of those diagnosed with the disorder, approximately 75% are male. No racial or ethnic predilection has been identified.
