Narcissistic Personality Disorder Prevalence and Comorbidity

According to the DSM IV-TR, Narcissistic Personality Disorder (NPD) is diagnosed in between 2% and 16% of the population in clinical settings (between 0.5-1% of the general population). The DSM-IV-TR proceeds to tell us that most narcissists (50-75% of all patients) are men. Narcissistic Personality Disorder (NPD) is often diagnosed with other mental health disorders ("co-morbidity"), such as mood disorders, eating disorders, and substance-related disorders. Patients with Narcissistic Personality Disorder (NPD) are frequently abusive and prone to impulsive and reckless behaviours ("dual diagnosis").
