Narcissism, as a complex personality trait, is characterized by extreme self-centrality, social
selfishness, lack of empathy and alexithymia. In this study, the origin, structural classification, adaptive
function and theoretical basis of narcissistic personality were comprehensively sorted out, and the
evidence related to the empathic disorder was also analyzed. These results contribute to a deeper
understanding of the relationship between narcissism and empathy, as well as to existing research,
and highlight the impact of both on individual mental health. Future research should focus on the
combination of electrophysiology, brain imaging and other techniques to explore the neurophysiological
mechanism of empathy disorders caused by narcissistic individuals.
