The online Free Dictionary describes ‘empathy’ as the ability to identify with or understand the perspective, experiences, or motivations of another individual and to comprehend and share another's emotional state. No surprise, some mental conditions such as antisocial personality disorder tend to be characterized by callousness, little if any remorse, manipulation of others, and lack of empathy. Can this be seen in brain scans? fMRI studies at the University of Chicago Department of Psychology revealed that the brains of individuals with antisocial personality disorder may be wired differently. fMRI results showed that these brains can be very sensitive to the thought of their own pain but the physical or social pain of others did not register as it did in the brains of individuals without this mental disorder. In addition, researchers found that when imagining others in physical or social pain, the brains of those with an antisocial personality disorder tended to show an increased response in a brain region known to be involved in the perception of pleasure. This is yet another reason to learn to recognize brain pathology as quickly as possible and take steps to protect yourself and be safe.
