Narcissists, Psychopaths, Sociopaths and Borderline Personality Disorder (BPD)


Personality disorders are complex and often misunderstood mental health conditions that can have a profound impact on an individual's ability to form healthy relationships and function effectively in society. Child abuse and neglect are significant risk factors that increase the likelihood of a more severe expression of psychopathic traits among vulnerable individuals.


Four of the most well-known and widely studied personality disorders are narcissistic personality disorder (NPD), psychopathy, sociopathy, and borderline personality disorder (BPD). While each of these disorders has its own unique set of characteristics, they also share some underlying similarities that are important to understand.


Narcissistic personality disorder is estimated to affect approximately up to 5% of the US population, with the condition being more prevalent in men than women.


Psychopathy, on the other hand, is believed to affect around up to 3.3% of the population, with a higher prevalence among incarcerated individuals. Psychopathy is considered of upmost importance in clinical settings because from it often reveals in younger years and worsens over time, becoming progressively less responsive to therapy treatment (Caldwell, McCormick, Wolfe, & Umstead, 2012; Kubak & Salekin, 2009; Lee, Salekin, & Iselin, 2010; Ribeiro da Silva et al., 2012, Ribeiro da Silva et al., 2013; Salekin, 2002; Salekin, Tippey, & Allen, 2012).


Sociopathy, which is sometimes used interchangeably with psychopathy, is thought to affect between 0.2% to 3.3% of the general population. Finally, borderline personality disorder is one of the most commonly diagnosed personality disorders, affecting approximately up to 5.9% of adults in the US.


What makes these conditions so intriguing is their complex interplay of cognitive, emotional, and behavioral factors. Narcissists often exhibit a grandiose sense of self-importance, a lack of empathy, and a preoccupation with fantasies of success and power. Psychopaths and sociopaths, on the other hand, are characterized by a disregard for the rights of others, a lack of remorse or guilt, and a tendency towards impulsive and antisocial behavior. Individuals with borderline personality disorder, in contrast, often experience intense and rapidly changing emotions, a fear of abandonment, and a pattern of unstable relationships.


Here is a comparison table outlining the similarities and differences between narcissists, psychopaths, sociopaths, and those with Borderline Personality Disorder (BPD):

Neurological Function Comparison


The prefrontal cortex, amygdala, anterior cingulate cortex, insula, and ventromedial prefrontal cortex play crucial roles in regulating emotions, understanding others, and guiding decision-making - all of which are disrupted in various ways across these disorders.


When looking at the overall patterns of brain functioning across the different conditions, the ones that appear most similar are:

  1. Psychopathy and Sociopathy: These two disorders show the most overlap in terms of brain regions involved. Both exhibit underactivity in the prefrontal cortex, amygdala, anterior cingulate cortex, and insula, which contributes to their shared characteristics of poor impulse control, lack of empathy, and disregard for the wellbeing of others.

  2. Borderline Personality Disorder (BPD) and ADHD: While not identical, BPD and ADHD share some notable similarities in brain functioning. Both are characterized by hyperactivity in the amygdala, leading to heightened emotional reactivity and dysregulation. Additionally, they both exhibit underactivity in the prefrontal cortex, anterior cingulate cortex, and ventromedial prefrontal cortex, which can contribute to impulsivity, decision-making challenges, and difficulties with cognitive control.

  3. Narcissistic Personality Disorder and Asperger's Syndrome: While the underlying mechanisms are different, narcissism and Asperger's share some commonalities in brain regions involved. Both exhibit underactivity in the anterior cingulate cortex and insula, which can lead to deficits in empathy and perspective-taking. Additionally, both conditions show prefrontal cortex abnormalities, though in opposite directions (overactivity in narcissists and underactivity in Asperger's).

The comparison table below highlights the patterns of brain functioning observed in these personality disorders.

Empathic Comparison

Empathy, the ability to understand and share the feelings of others, is a critical component of healthy social and emotional functioning. However, individuals with certain personality disorders often exhibit profound deficits or distortions in their capacity for empathy.


This empathic analysis will explore the nuanced differences in how narcissists, psychopaths, sociopaths, and those with borderline personality disorder (BPD) perceive, experience, and respond to the emotional states of others.


By examining the multi-faceted nature of empathy across these personality disorders, we can gain a deeper appreciation for the complex interplay between one's capacity for emotional understanding and their overall psychological functioning. There are different types of empathy:

  1. Cognitive Empathy: This is the ability to understand and recognize another person's perspectives, thoughts and experiences from their point of view. It's about intellectually understanding what someone else is going through.

  2. Emotional Empathy: This is the ability to actually feel and share the emotions of another person. It's about vicariously experiencing the feelings of someone else, whether it's joy, sadness, anger, etc.

  3. Compassionate Empathy: This involves not just understanding and feeling the emotions of others, but also feeling intrinsic motivated to help.

  4. Somatic Empathy: This refers to the somatic and physical experience of mirroring the bodily sensations and expressions of others. For example, feeling your body tense up when someone else is in pain.

  5. Empathic Concern: Also called "sympathy", this is the feeling of concern and care for another person's wellbeing. It's the desire to support and comfort someone who is struggling.

  6. Affective Empathy: This is the automatic, emotional response to another person's emotional state. It's the instinctive sharing of feelings without necessarily understanding the reason behind them.

  7. Cognitive-Affective Empathy: This is the ability to both intellectually understand and emotionally resonate with someone else's experiences and emotions. It's the most complete form of empathy.
