For clinicians, the assiduous and sustained resistance to change common in patients with narcissistic personality disorder (NPD) has been especially noticeable and trying. However, until recently the natural course of NPD has not received much attention in the clinical and empirical literature, and there is very little documented knowledge about the factors that might contribute to changes.

Personality disorders are characterized by the presence of inflexible and maladaptive patterns of perceiving oneself and relating to the environment that result in psychosocial impairment or subjective distress. The enduring nature of the behaviors, their impact on social functioning, the lack of clear boundaries between normality and illness, and the patient's perception of the symptoms as not being foreign make this group of conditions more difficult to conceptualize than the more typical, episodic mental disorders.

Psychopathy (renamed antisocial personality disorder) is marked by persistent violations of social norms, including lying, stealing, truancy, inconsistent work behavior and traffic arrests.
