Narcissistic personality disorder is marked by a strong need to be admired, an exaggerated sense of self-importance, and a lack of empathy. In the DSM-5 classification used by the American Psychiatric Association, personality disorders are grouped into clusters A, B, and C. Narcissism—along with borderline and antisocial personality disorders—belongs to Cluster B, which is often associated with attention-seeking, a tendency toward conflict, emotional instability, and theatrical behavior.
Narcissistic traits most often become noticeable in adolescence or early adulthood, when emotions run high and young people face the challenge of evaluating themselves and their actions. Thoughts such as “I’m meant for something more” or “I’m exceptional” may appear. For many people, these beliefs fade with age. However, if they are intense and interfere with everyday functioning, it is worth consulting a specialist.
People affected by this disorder often stand out and can strongly irritate those around them, creating tension. They may exaggerate their achievements and talents, believe they are superior, and demand admiration. They frequently struggle to accept other people’s success, may act arrogantly or jealously, and can exploit even close relationships to achieve their own goals.
Being in a relationship with a narcissist can be extremely difficult. The partner may be pushed into chronic guilt, made to feel inferior, humiliated, or gradually isolated from other people. If you believe you are living with a narcissist, you can suggest that they seek professional help—but just as importantly, do not hesitate to look for support for yourself.
During the course of the disorder, brief psychotic episodes may occur, often triggered by a clash between grandiose self-beliefs and how the person is actually perceived by others. Depressive states can also appear, especially when the need to feel important is not satisfied.
In addition to the more widely discussed grandiose form of narcissism—characterized by poor understanding of others, exploitation, and antagonizing behavior—specialists also describe a vulnerable form. In this variant, a person may still display classic narcissistic behaviors but can also be withdrawn, distrustful, and closed off. Such individuals may be more willing to seek help.
Narcissistic tendencies can appear as part of normal personality development. In adulthood, however, most people reduce them to a level that is seen not as a disorder but as a personality trait.
According to the DSM-5, narcissistic personality disorder may be diagnosed in an adult who shows several narcissistic traits that persist over time and significantly affect functioning in different areas of life.
Some sources estimate that narcissistic personality disorder may affect up to around 6% of the population. Diagnosis is made by a physician—specifically, a psychiatrist. Risk factors include harmful family dynamics and neglect in upbringing, especially a lack of empathy from the mother, communicating to a child that they deserve love only when they achieve something, and alternating between idealizing and devaluing the child by caregivers.
People who seek professional support are often referred to psychotherapy, where they can learn healthier patterns of behavior and build more balanced relationships.
