A personality disorder affects the way a person thinks, behaves, and relates to others. According to the American Psychiatric Association, the essential features of a personality disorder are impairments in personality (self and interpersonal) functioning and the presence of pathological personality traits.

When Is Narcissism a Personality Disorder?

Holly Crisp-Han, MD, a psychiatrist and clinical associate professor at Baylor College of Medicine in Houston and the co-author of Narcissism and Its Discontents, says everyone has narcissistic tendencies from time to time. However, those tendencies become a personality disorder when a person’s ability to function and engage with others is affected. “The clinical manifestation of narcissism is narcissistic personality disorder,” says Ramani Durvasula, PhD, a professor emerita of psychology at California State University in Los Angeles. “This is a persistent and pathological pattern and causes the person distress and dysfunction.”

Considering themselves very importantNot taking criticism wellHaving an outsized sense of their own potential successHaving a need to be admired

“If feeling superior or having grandiose ideas about your place in the world is getting in the way of your living a happy life, it’s time to talk to a mental health professional to discuss treatment to help you live your best life,” says Dr. Crisp-Han. Grandiose narcissism is associated with displays of superiority, entitlement, and extraverted behavior. Vulnerable narcissism also involves self-absorbed behavior, but it is associated with self-consciousness, insecurity, and introversion. Narcissism is more common in men than women. It can often begin in teenage years or early adulthood. While children can display narcissistic tendencies, it may be more an indication of their age and stage of development. In fact, it is normal for a very small child to be narcissistic and believe that small accomplishments are major and that they are the center of the universe. While it is good for parents to indulge this age-appropriate narcissism, it becomes developmentally important in later years to help older children recognize others’ feelings and accomplishments.

An in-depth psychological evaluationAn assessment of criteria for diagnosis based on the latest version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association

A diagnosis of NPD in the DSM-5 includes these criteria, according to PsychDB:

Has a grandiose sense of self-importanceIs preoccupied with fantasies of unlimited success, power, brilliance, beauty, or ideal loveBelieves that they are special and unique and can only be understood by, or should associate with, other special or high-status people (or institutions)Requires excessive admirationHas a sense of entitlementIs interpersonally exploitative (such as taking advantage of others to achieve his or her own ends)Lacks empathy — is unwilling to recognize or identify with the feelings and needs of othersIs often envious of others or believes that others are envious of themShows arrogant, haughty behaviors or attitudes

A diagnosis of narcissism requires that these personality traits continue over time, are consistent in different situations, are not normal based on the person’s stage of development or their social or cultural environment, and are not the result of drug or alcohol use or a medication the person is taking.

Prognosis of Narcissism

The outcome for people with NPD might depend on different factors, such as how severe their condition is, whether they have other psychiatric disorders, and how they respond to treatment. Individual, couples, or group therapy can help people with NPD learn some of these new emotional skills:

Accepting and maintaining personal and work relationshipsRecognizing and accepting what they can and can’t do, so that it’s easier to handle criticism or failuresUnderstanding and regulating feelingsUnderstanding and regulating issues of self-esteemNot pursuing goals that aren’t reachable, and embracing goals that are

Cognitive behavioral therapy (CBT) can be very helpful for people with narcissism. CBT is a type of psychotherapy that focuses on strategies and solutions to change unhelpful thoughts and harmful behavior patterns. People with narcissism may not initially see the value in therapy or have difficulty sticking with their treatment. Crisp-Han points out that managing the condition “can take a long time, and the person must really want treatment.”
