Course and Prognosis
 
Narcissistic Personality Disorder (NPD) is difficult to treat and resistant to change.  Because the behavioral patterns—especially with regard to how the person relates to others—are difficult to change, the prognosis for NPD is poor.  By definition, the narcissist believes that he or she is superior; thus, it is difficult for this person to entertain the notion that something about them needs changing, let alone is maladptive.
