Nevertheless, it is important that the diagnosis of Narcissistic Personality Disorder is differentiated from the normal symptoms of grandiosity in that. research has indicated that the pathological form of Narcissistic Personality Disorder occurs in two forms. One form is the grandiose state of mind in young people, which can eventually be corrected by the individuals’ life experiences, while the second form is the less severe grandiosity that persists through to adulthood, majorly characterized by disturbed and turbulent interpersonal relations (Hesse, Schliewe & Thomsen, 2005). Nonetheless, while determining that an individual is suffering from the Narcissistic Personality Disorder, the specialists must apply the elimination criteria, to rule out other disorders, in order to finally define the disorder as Narcissistic Personality Disorder.
