Narcissistic Personality Disorder

What is Narcissistic Personality Disorder?

Narcissistic personality disorder is where a person has a feeling of grandiosity and superiority over others and demands attention; such people tend to be arrogant and lack empathy for others.

Narcissistic personality disorder is classified under Cluster B personality disorders which are characterized by dramatic, emotional or erratic behavior. Other personality disorders in this cluster include borderline personality disorder, antisocial personality disorder and histrionic personality disorder.

Many of us are familiar with the mythological story of Narcissus and Echo, from Ovid’s Metamorphoses. Narcissus, a young lad rejects the love of Echo and falls in love with his own reflection in the pond. A person with Narcissistic personality disorder is in a similar situation, where he falls in love with a false image of himself.

It affects around 0.5% to 1% individuals. Most of those affected are males, though it can also affect females. Though the condition is usually diagnosed at adulthood, more often than not, the trauma that causes the condition can be traced to childhood. A genetic predisposition has also been suggested.

Narcissistic personality disorder is diagnosed based on the DSM-5 criteria and the ICD-10 criteria. It may be difficult to convince the patient that he has a problem and to consult a therapist for treatment due to the grandiose attitude. However, the patient may benefit with counseling and other therapies.

Causes of Narcissistic Personality Disorder

The exact cause of narcissistic personality disorder is not known, though several have been suggested. These include:

  • Genetic factors: Some individuals who developed narcissistic personality disorder in adulthood have shown different temperaments while they were infants. This indicates the possibility of genetic factors in the causation of narcissistic personality disorder
  • Environmental factors: The relationship of a child with the parent/parents can have an impact on the child and influence the development of narcissistic personality disorder. Trauma experienced by a person in childhood at the hands of parents or others can have a deep impact resulting in narcissistic personality disorder in later years. Thus, the development of narcissistic personality disorder can be considered as a form of defense mechanism, where the person generates a false self-image that he/she can idolize and expect others to do the same.
