Brain difference in psychopaths identified
Date:8/4/2009

Professor 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.'

While psychopathy is strongly associated with serious criminal behaviour (eg rape and murder) and repeat offending, the biological basis of psychopathy remains poorly understood. Also some investigators stress mainly social reasons to explain antisocial behaviours. To date, nobody has investigated the 'connectivity' between the specific brain regions implicated in psychopathy.

Earlier studies had suggested that dysfunction of specific brain regions might underpin psychopathy. Such areas of the brain were identified as the amygdale, ie the area associated with emotions, fear and aggression, and the orbitofrontal cortex (OFC), the region which deals with decision making. There is a white matter tract that connects the amygdala and OFC, which is called the uncinate fasciculus (UF). However, nobody had ever studied the UF in psychopaths. The team from King's used an imaging metho
