Psychiatric care could be administered more effectively due to the findings of a recent report identifying differences in the brain of psychopaths.
Psychopaths with murder convictions and perpetrators of other serious crimes were found to have biological differences in their brains, which could explain their behaviour.
A section of the brain known as the amygdale, which is linked to fear, emotions and aggression, and the orbitofrontal cortex (OFC), which is associated with decision-making were found to have anomalies in psychopaths.
The study, carried out by scientists at the Institute of Psychiatry at King's College London, is to be published in the journal Molecular Psychiatry.
Dr Michael Craig, who was on the team that carried out the study, commented: "If replicated by larger studies the significance of these findings cannot be underestimated.
"The suggestion of a clear structural deficit in the brains of psychopaths has profound implications for clinicians, research scientists and the criminal justice system."
Psychopathy concerns immoral and antisocial behaviour repeatedly perpetuated and can also be termed sociopathy.
