People who suffer from self-loving personality upset , which is characterized by utmost arrogance and ego - absorption , have structural abnormality in a part of the brain that has been linked to empathy , a novel study finds .
Researchers used magnetised reverberance imaging to rake the brains of 34 mass , include 17 individuals who suffer fromnarcissistic personality disorderliness , and found that pathological narcissists have less gray affair in a part of the intellectual cortex call the left over anterior insula . Gray topic is chiefly composed of neuron cell bodies and non - neuron brain cell that provide food and energy to neurons , rather than sending and receiving information .
Narcissistic personality disorder is characterized by extreme vanity, arrogance and self-absorpotion, according to the American Psychiatric Association.
Individuals with narcissistic personality disorderliness brook from low self - esteem and feelings of inferiority , while also projecting display of arrogance and conceit , according to the American Psychiatric Association .
One of the key traits of pathologic narcissists is their clear lack of empathy , say Stefan Röpke , a professor in the section of psychopathology at the Charité - Universitätsmedizin Berlin in Germany . Generally , these patient are able to recognise what others feel and think , but externally exhibit little compassion . [ The 10 Most Controversial Psychiatric Disorders ]
The odd anterior insula region of the brain , which is thought to be regard with cognitive functioning and the regulation of emotion , has also been link up to the coevals of compassionateness and empathy .
" This was already a realm of interest for empathy , but for the first time , we were able to show that it is structurally correlated in the nous , " Röpke tell apart LiveScience .
The researchers see that the stage to which a person was able toexhibit empathywas marry to the volume of gray matter in the brain , both in the mathematical group of healthy individuals and among those with egotistical personality disorder . The determination suggests that disregardless of personality disorder , the left prior insula plays an of import function in feeling and expressing compassion , Röpke read .
" These results are authoritative because they pose very well with our hypothesis of egotistical personality disorderliness , " Röpke aver .
Next , the investigator intend to investigate how the volume of greyish matter in the intellectual lens cortex affects the interplay between variousregions of the brain . Röpke and his colleague will use functional magnetic reverberance imagination , which is a technique to assess wit action based on cerebral blood stream , to learn the functions of the left anterior insula , and how the nous ’s various networks differ in patient role with narcissistic personality disorderliness .
" It ’s not just one neighborhood or brain location that is creditworthy for empathy , " Röpke said . " We want to understand how this region works , and what find when it does n’t function well . "
The elaborate results of the study were issue online June 17 in the Journal of Psychiatric Research .
