Narcissistic personality disorder is characterized by a long-standing pattern of grandiosity (either in fantasy or actual behavior), an overwhelming need for admiration, and usually a complete lack of empathy toward others. People with this disorder often believe they are of primary importance in everybody’s life — and to anyone they meet. While this pattern of behavior may be appropriate for a king in 16th century England, it is generally considered inappropriate for most ordinary people today.
People with narcissistic personality disorder often display snobbish, disdainful, or patronizing attitudes. For example, an individual with this disorder may complain about a clumsy waiter’s “rudeness” or “stupidity,” or conclude a medical evaluation with a condescending evaluation of the physician.
In layperson terms, someone with this disorder may be described simply as a “narcissist” or as someone with “narcissism.” Both of these terms generally refer to someone with narcissistic personality disorder.
A personality disorder is an enduring pattern of inner experience and behavior that deviates from the norm of the individual’s culture. The pattern is seen in two or more of the following areas: cognition; affect; interpersonal functioning; or impulse control. The enduring pattern is inflexible and pervasive across a broad range of personal and social situations. It typically leads to significant distress or impairment in social, work or other areas of functioning. The pattern is stable and of long duration, and its onset can be traced back to early adulthood or adolescence.
In order for a person to be diagnosed with narcissistic personality disorder (NPD) they must meet five or more of the following symptoms:
Because personality disorders describe long-standing and enduring patterns of behavior, they are most often diagnosed in adulthood. It is fairly uncommon for them to be diagnosed in childhood or adolescence, because a child or teen is under constant development, personality changes, and maturation. However, if it is diagnosed in a child or teen, the features must have been present for at least 1 year.
Narcissistic personality disorder is more prevalent in males than females and is thought to occur in around 6 percent of the general population, according to research.
Like most personality disorders, NPD typically will decrease in intensity with age, with many people experiencing few of the most extreme symptoms by the time they are in their 40s or 50s.

Personality disorders such as NPD are typically diagnosed by a trained mental health professional, such as a psychologist or psychiatrist. Family physicians and general practitioners are generally not trained or well-equipped to make this type of psychological diagnosis. So while you can initially consult a family physician about this problem, they should refer you to a mental health professional for diagnosis and treatment. There are no laboratory, blood, or genetic tests that are used to diagnose personality disorder.
Many people with this disorder don’t seek out treatment. People with personality disorders, in general, do not often seek out treatment until the disorder starts to significantly interfere or otherwise impact a person’s life. This most often happens when a person’s coping resources are stretched too thin to deal with stress or other life events.
A diagnosis for narcissistic personality disorder is made by a mental health professional comparing your symptoms and life history with those listed here. They will make a determination whether your symptoms meet the criteria necessary for a personality disorder diagnosis.
Researchers today don’t know what causes NPD. There are many theories, however, about the possible causes of narcissistic personality disorder.
Most professionals subscribe to a biopsychosocial model of causation — that is, the causes are likely due to biological and genetic factors, social factors (such as how a person interacts in their early development with their family and friends and other children), and psychological factors (the individual’s personality and temperament, shaped by their environment and learned coping skills to deal with stress). This suggests that no single factor is responsible — rather, it is the complex and likely intertwined nature of all three factors that are important.
If a person has this personality disorder, research suggests that there is a slightly increased risk for this disorder to be “passed down” to their children. While some of this has to do with genetics, some of is also likely due to the child’s personality, as well as the parenting behavior of one or both of the parents.
Treatment of narcissistic personality disorder typically involves long-term psychotherapy with a therapist that has experience in treating this kind of personality disorder. Medications may also be prescribed to help with specific troubling and debilitating symptoms.
