Brain difference in psychopaths identified

Human BrainProfessor Declan Murphy and colleagues Dr Michael Craig and Dr Marco Catani from the Institute of Psychiatry at King’s College London have found differences in the brain which may provide a biological explanation for psychopathy. The results of their study are outlined in the paper ‘Altered connections on the road to psychopathy’, published in Molecular Psychiatry.

The research investigated the brain biology of psychopaths with convictions that included attempted murder, manslaughter, multiple rape with strangulation and false imprisonment. Using a powerful imaging technique (DT-MRI) the researchers have highlighted biological differences in the brain which may underpin these types of behaviour and provide a more comprehensive understanding of criminal psychopathy.

Dr Michael Craig said: ‘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.’
