What is a Narcissistic Sociopath?

A narcissistic sociopath is someone with a combination of narcissistic personality disorder and definitive behavioral signs of sociopathy. People with narcissism are characterized by their excessive and persistent need for others' admiration and positive reinforcement. They generally have grandiose opinions of themselves and believe they are superior to other people. Narcissists are also frequently convinced that they are above the normal responsibilities and obligations of everyday life, so they usually have significant difficulties maintaining employment or relationships as a result. The narcissistic sociopath has this type of personality along with a noticeable lack of regard for the rights of others and a tendency to regularly violate those rights. 

One noted difference between a narcissistic sociopath and people with narcissism alone is that the narcissist with the sociopathy reacts strongly and sometimes even violently to negative feedback. True sociopaths generally do not respond to criticism or care what others may think of them. A narcissistic sociopath is unable to tolerate criticism and needs constant praise, as well as deference from other people. Many with this condition present themselves in the best light possible and are able to easily charm others to gain their trust. 

A definite characteristic of a narcissistic sociopath is a tendency to view others not as fellow human beings, but rather as tools or means to an end. If certain other people are deemed unable to further the narcissistic sociopath's given agenda, they are normally cast aside. People diagnosed with this type of personality disorder usually do not have boundaries when it comes to manipulating and victimizing others if doing so will lead to their own benefit. This behavior trait can usually make romantic relationships with a narcissistic sociopath particularly destructive emotionally, mentally, and often financially. Many former spouses or partners of these individuals report that recovering from the relationship can take a long time. 

Causes of narcissism are commonly attributed to abusive or dysfunctional early years, although some psychologists claim that specific biological differences in brain chemistry may also be partially to blame. Exact causes of sociopathic behavior are similarly subject to debate. When these two personality conditions coexist in the same person, some mental health professionals report that treating narcissism often yields better results than most attempts to treat sociopathy. Others maintain that most narcissistic sociopaths are largely untreatable through any kinds of established therapies, so the most that society can do is establish protective measures against these individuals' destructive behaviors.
