What’s Going On In A Narcissistic Brain?
Neurobiological explanations for narcissism.

When we understand the neurobiological differences between a person with and without a personality disorder, we can isolate potential causes and treatment opportunities.
“Early life intervention also offers hope of preventing dysfunction associated with abuse, neglect and adversity that in many instances are-direct normal brain and mind trajectories toward personality disorder.” — Dragan M. Svrakic & Charles F. Zorumski.
Because narcissistic personality disorder (NPD) often leads to interpersonal dysfunction, the social brain is of particular interest; the temporal-parietal junction, posterior superior temporal sulcus, medial prefrontal cortex, anterior cingulate cortex, amygdala, and interrelated regions.
I recently shared a story highlighting studies and behaviours that suggest narcissists know they’re narcissistic:
Now, I’m writing a story that looks into the neurobiological reasoning behind narcissism. However, for the following reasons, I disagree that “… [narcissistic] behaviour is not carried out by choice — the distorted view of the reality of a narcissist is a result of grey matter deficiency in the frontal lobe of the brain’.
- Most studies have yet to identify whether or not the differences are a result of narcissism, or the other way around.
- You can increase the amount of white and grey matter in the brain and other forms of neuroplasticity.
- Alterations in grey matter, cortical volume, neural circuitry, and other neurobiological structures and functions can lead to any number of cognitive, emotional, behavioural, and physiological disorders.
- Deciding to behave in a certain way takes multiple processes across multiple regions of the brain, and narrowing it down to one region negates very rich and real historical, cultural, contextual, and environmental influences.
