Personality disorders are rarely single issues and, yes, there are degrees. Don’t know if anyone put this up yet but here are the symptoms.
Symptoms of Narcissistic Personality Disorder
In order for a person to be diagnosed with narcissistic personality disorder (NPD) they must meet five or more of the following symptoms:
Has a grandiose sense of self-importance (e.g., exaggerates achievements and talents, expects to be recognized as superior without commensurate achievements)
Is preoccupied with fantasies of unlimited success, power, brilliance, beauty, or ideal love
Believes that he or she is “special” and unique and can only be understood by, or should associate with, other special or high-status people (or institutions)
Requires excessive admiration
Has a very strong sense of entitlement, e.g., unreasonable expectations of especially favorable treatment or automatic compliance with his or her expectations
Is exploitative of others, e.g., takes advantage of others to achieve his or her own ends
Lacks empathy, e.g., is unwilling to recognize or identify with the feelings and needs of others
Is often envious of others or believes that others are envious of him or her
Regularly shows arrogant, haughty behaviors or attitudes
As per my earlier posting...
“The group of malignant narcissists are different from normal human beings in that they have no conscience, no remorse, no guilt, no ability to feel pity or compassion for others.”
