The narcissist is described as turning inward for gratification rather than depending on others and as being excessively preoccupied with issues of personal adequacy, power and prestige.
The ICD-10 (International Classification of Mental and Behavioural Disorders, published by the World Health Organisation in Geneva 1992) regards narcissistic personality disorder (NPD) as "a personality disorder that fits none of the specific rubrics". It relegates it to the category known as "Other specific personality disorders", which also includes the eccentric, "haltlose", immature, passive-aggressive, and psychoneurotic personality disorders.
ICD-10 states that Narcissistic Personality Disorder is "a personality disorder that fits none of the specific rubrics F60.0-F60.7". That is, this personality disorder does not meet the diagnostic criteria for any of the following:
Some narcissistic traits are common and a normal developmental phase. When these traits are compounded by a failure of the interpersonal environment and continue into adulthood they may intensify to the point where NPD is diagnosed. It has been suggested that NPD may be exacerbated by the onset of aging and the physical, mental, and occupational restrictions it imposes as can most personality traits.
Pathological narcissism can develop from an impairment in the quality of the person's relationship with their primary caregivers, usually their parents, in that the parents were unable to form a healthy, empathic attachment to them. This results in the child conceiving of themselves as unimportant and unconnected to others. The child typically comes to believe that he or she has some defect of personality which makes them unvalued and unwanted .
Narcissistic Personality Disorder (NPD) is isolating, disenfranchising, painful, and formidable for those diagnosed with it and often those who are in a relationship with them. Distinctions need to be made among those who have NPD because not each and every person with NPD is the same. Even with similar core issues, the way in which one's individual narcissism manifests itself in his or her relationships varies.
To the extent that people are pathologically narcissistic, they can be controlling, blaming, self-absorbed, intolerant of others’ views, unaware of others' needs and of the effects of their behavior on others, and insistent that others see them as they wish to be seen . They may also demand certain behavior from their children because they see the children as extensions of themselves, and need the children to represent them in the world in ways that meet the parents’ emotional needs . (For example, a narcissistic father who was a lawyer demanded that his son, who had always been treated as the "favorite" in the family, enter the legal profession as well. When the son chose another career, the father rejected and disparaged him.)
These traits will lead overly narcissistic parents to be very intrusive in some ways, and entirely neglectful in others. The children are punished if they do not respond adequately to the parents’ needs. This punishment may take a variety of forms, including physical abuse, angry outbursts, blame, attempts to instill guilt, emotional withdrawal, and criticism. Whatever form it takes, the purpose of the punishment is to enforce compliance with the parents' narcissistic needs.
People who are overly narcissistic commonly feel rejected, humiliated and threatened when criticised. To protect themselves from these dangers, they often react with disdain, rage, and/or defiance to any slight criticism, real or imagined . To avoid such situations, some narcissistic people withdraw socially and may feign modesty or humility.
Though individuals with NPD are often ambitious and capable, the inability to tolerate setbacks, disagreements or criticism, along with lack of empathy, make it difficult for such individuals to work cooperatively with others or to maintain long-term professional achievements . With narcissistic personality disorder, the person's perceived fantastic grandiosity, often coupled with a hypomanic mood, is typically not commensurate with his or her real accomplishments.
The exploitativeness, sense of entitlement, lack of empathy, disregard for others, and constant need for attention inherent in NPD adversely affect interpersonal relationships.
Gabbard suggested NPD could be broken down into two subtypes. He saw the "oblivious" subtype as being grandiose, arrogant and thick skinned and the "hypervigilant" subtype as easily hurt, oversensitive and ashamed.
He suggested that the oblivious subtype presents a large, powerful, grandiose self to be admired, envied and appreciated. This self is the antithesis of the weakened and internalised self that hides in a generic state of shame. This is how the internalized self fends off devaluation, while the hypervigilant subtype neutralises devaluation by seeing others as unjust abusers. This hypervigilent type does not fend off devaluation; he is obsessed with it.
Jeffrey Young, who coined the term "Schema Therapy", a technique originally developed by Aaron T. Beck (1979), also links shame to NPD. He sees the so-called Defectiveness Schema as a core schema of NPD, next to the Emotional Deprivation and Entitlement Schemas. . The Defectiveness Schema is compensated with three Schema Modes (coping strategies):
Note that an individual with this schema might not employ all three schema modes.
