Causes, Risk Factors, And Complications Of Narcissistic Personality Disorder
Mismanagement Of Setbacks

The mismanagement of the setbacks of life is a strong factor in the development of narcissistic personality disorder. Everyone experiences failure and criticism as they grow. Part of becoming a mature person is developing the resiliency to handle such disappointments; to learn and grow through them. When an individual is taught, either through parenting or culture, these setbacks are not a normal part of life and are always someone else's fault, it can lead to a narcissistic view of the world. Because narcissism is often a product of low self-esteem, the narcissist is most comfortable when they can blame others for misfortune, maintaining the illusion they are too special and important for failure or shortcomings. This habitual pattern of thinking can then develop into narcissistic personality disorder.
Significant Relationship Difficulties

Narcissistic personality disorder patients often experience significant relationship difficulties not only in their romantic relationships, but also in their familial relationships, friendships, and work relationships. An individual with untreated NPD will often prioritize themselves above all else and expect others to do the same, but they may not offer support for others in return.
They have difficulty recognizing the needs of others and may consciously or unconsciously manipulate others to get what they want. One of the most important things to do in any relationship is to set healthy boundaries. This becomes doubly vital for individuals with narcissistic personality disorder and those close to them, as healthy boundaries give the affected individual rules to live by that they may not instinctively know.
