Narcissistic Personality Disorder
Causes of Narcissistic Personality Disorder
Genes and environmental factors may contribute to the development of narcissistic personality disorder. One theory suggests that caregivers may have interacted with the child in a way that did not help the child develop a stable sense of self. For example, caregivers may have been overly critical of or praised, admired, or indulged the child too much. Some people with narcissistic personality disorder have special gifts or talents and become used to associating their self-image and sense of self with the admiration and esteem of others.
