Answer 1

Assuming this is a legitimate diagnosis, it is almost impossible to deal with a person with this disorder and it is difficult to treat. If possible don't have contact with him/her.
On the other hand a person going through adolescence might exhibit some of the same behaviors without having the disorder.

Answer 2

Narcissistic personality disorder is a serious emotional disturbance characterized by a grandiose, or extremely exaggerated, sense of self-importance. Individuals with this disorder lack empathy for other people but need constant admiration from them.

Narcissistic personality disorder is one of several types of personality disorders, all of which reflect an inability in the affected person to accept the demands and limitations of the world. These disorders may regularly interfere with a person's behavior and interactions with family, friends or co-workers. Among the other personality disorders are paranoid personality disorder, antisocial personality disorder, borderline personality disorder and obsessive-compulsive personality disorder.

Although people with narcissistic personality disorder have an exaggerated image of their own importance, they have vulnerable self-esteems and often don't like themselves. Therefore, they seek attention that confirms their grandiosity. When feedback doesn't validate their exaggerated image, they tend to lash out or withdraw.
