The hallmarks of narcissistic personality disorder (NPD) are grandiosity, a lack of empathy for other people, and a need for admiration. People with this condition are frequently described as arrogant, self-centered, manipulative, and demanding. They may also have grandiose fantasies and may be convinced they deserve special treatment. These characteristics typically begin in early adulthood and must be consistently evident in multiple contexts, such as at work and in relationships.

People with NPD often try to associate with other people they believe are unique or gifted in some way, which can enhance their own self-esteem. They tend to seek excessive admiration and attention and have difficulty tolerating criticism or defeat.

The causes of narcissistic personality disorder are not yet well understood. Genetic and biological factors, as well as environment and early life experiences, are all thought to play a role in the development of this condition.

Treatment for narcissistic personality disorder can be challenging because people with this condition present fantastic grandiosity and defensiveness, making it difficult to acknowledge problems and vulnerabilities. Psychotherapy may help people with narcissistic personality disorder relate to others more healthily and compassionately.

Individuals with narcissistic personality disorder, according to the DSM-5, exhibit five or more of the following, which are present by early adulthood and across contexts:

– A grandiose sense of self-importance.
– Preoccupation with fantasies of unlimited success, power, brilliance, beauty, or ideal love.
– Belief that one is special can only be understood by or associated with particular people or institutions.
– A need for excessive admiration.
– A sense of entitlement (to special treatment).
– Exploitation of others.
– A lack of empathy.
– Envy of others or believing that one is the object of envy.
– Arrogant, haughty behavior or attitudes.
