They found a combination of factors, like an indulgent or permissive parenting styles, genetics, and early-in-life temperament, increased the likelihood of a child developing narcissism in their early twenties.
Signs that a child may be a narcissist include a lack of empathy; unrealistic sense of self-importance; lack of recognition of attention and admiration; and an overall struggle in social and family relationships.
According to Thomaes & Brummelman, the development of narcissism begins at around the ages of 7 or 8. This is the time when children begin to evaluate themselves according to how they perceive others. Although narcissism comes partly down to genes, it is also impacted by the environment.
The results are quite clear: Parents who "overvalue" children during this developmental stage, telling them they are superior to others and entitled to special treatment, are more likely to produce narcissistic children -- who can grow up to become narcissistic adults, unless something is done about it.
But children who were extremely melodramatic, and who also had parents that ignored or neglected them, spoiled them constantly, or insisted on perfection, were more likely to become narcissists in adulthood.
Summary: For most people, narcissism wanes as they age. A new study reports the magnitude of the decline of narcissistic traits is tied to specific career and personal relationship choices. However, this is not true for everyone.
It is no wonder then, that children of narcissists very often become narcissistic themselves, having 'learned' narcissism from their very own beginnings. In developing 'work arounds' to appease their narcissistic parent, they are actually wiring these patterns into their brains as normal.
Dr. Brunell says, “The child typically suffers from low psychological well-being, such as low self-esteem, depression, and anxiety. They tend to try to please others and have poor ability to set boundaries or to say no to people's requests.
A narcissistic parent will often abuse the normal parental role of guiding their children and being the primary decision maker in the child's life, becoming overly possessive and controlling. This possessiveness and excessive control disempowers the child; the parent sees the child simply as an extension of themselves.
Parental overvaluation was the largest predictor of a child's narcissism over time, but interestingly, it did not predict self-esteem. In other words, telling kids how exceptional they are doesn't produce kids with good healthy self-esteem – it just makes them more narcissistic.
At the end of a relationship, narcissists may become combative, passive-aggressive, hostile, and even more controlling. People with NPD often fail to understand other people's needs and values. They are hyper focused on their egos, but do not account for how their actions affect others.
On the one hand, some narcissists may genuinely care for and love their mothers. On the other hand, they may view their mothers as a source of support and comfort and feel a deep affection towards them. However, it is also true that many narcissists struggle to form close, loving relationships with others.
It is important to note that overall narcissism scores generally declined from age 18 to age 41. So, when a life experience is associated with higher levels of a facet of narcissism at age 41, it means that having this life experience led this facet of narcissism to decline less than expected.
The narcissist often engages in self-defeating and self-destructive behaviours.
According to Julie L. Hall, author of “The Narcissist in Your Life: Recognizing the Patterns and Learning to Break Free,” narcissists become more extreme versions of their worst selves as they age, which includes becoming more desperate, deluded, paranoid, angry, abusive, and isolated.
Grandiose sense of self-importance
Grandiosity is the defining characteristic of narcissism. More than just arrogance or vanity, grandiosity is an unrealistic sense of superiority. Narcissists believe they are unique or “special” and can only be understood by other special people.
Generally, narcissists are very frugal with their money and defensive with it. When it comes to their possessions, they don't give them freely. There is, however, more to this greed than self-preservation. Due to their lack of empathy, narcissists may not understand the benefits of sharing their resources.
While an outward show of superiority is a definite part of the narcissistic personality, a sense of superiority (or pursuit of it) is not the central factor of the disorder. The root of the disorder is actually a strict resistance to feeling vulnerable with anyone at any time.
Golden children are usually raised by narcissistic parents who are controlling and authoritarian. They coerce their child into being “perfect” by creating a toxic environment where the children do not feel safe voicing their own opinions or going against any rules.
A golden child's sense of self and their personal boundaries are erased, as their own sense of identity is replaced with the need to live up to their role. Their behaviors and beliefs reflect what their parent expects of them, and they may feel incapable of individuation even in adulthood.
