The lack of empathy you see in narcissism can be similar to the lack of empathy you see in antisocials (sociopathy). You would think a narcissist would respond more to the needs of others but in the DSM you see no apparent distinction when they mention this. The big distinction between both diagnosis is that individuals with antisocial personality disorder and narcissistic personality disorder although share a tendency to be tough-minded, glib, exploitative, and lack empathy, individuals with antisocial personality disorder may not be as needy of the admiration of others.
