Narcissism - Brain and Behavior : Self-Views and Empathy in the Narcissistic Brain

Abstract: This thesis reviews both psychological and neural research in the fields of self-evaluation, self-views and self-enhancement bias. The research has made associations to grandiosity and need for admiration, which are two of the defining characteristics of narcissistic personality disorder. Neural correlates associated with this research are the medial prefrontal cortex, orbitofrontal cortex, posteromedial cortex and anterior insula. Narcissists have been seen to have a decreased form of emotional empathy even though they rate themselves to have higher emotional empathy than they actually have, which is linked to self-enhancement bias and grandiosity. Alexithymia has not gained much attention in relation to narcissism, but research presented suggests that this might need to change. Neural correlates that are associated with lack of emotional empathy and alexithymia are the anterior insula, frontoparalimbic areas and the medial prefrontal cortex. Narcissistic personality disorder is in the DSM-5 specified to be defined by a grandiose sense of self, a need for admiration, and a lack of empathy in either fantasy or behavior. However according to researchers in the field this only covers a part of the spectrum of narcissism. Deficits in the DSM-5 will he highlighted, as well as suggestions on what to do in order to help clarify the definition in DSM-5 and the concept in general.
