Results: The offenders with ASPD Pus demonstrated reduced grey matter volume in the bilateral anterior rostral medial prefrontal cortex (arMPFC) and bilateral anterior temporal areas.
These areas are known to play key part in some functions impaired in ASPD Plus. for example: the medial prefrontal cortex monitors and coordinates complex social goals. The arMPFC engages in self-reflective processing and enables an emotional understanding of others’ intentional acts. It also facilitates the si- multaneous consideration of self and other perspectives. It is also involved in fear appraisal.The temporal poles are thought to be important in using stored social knowledge and contextual framing to facilitate understanding of social stimuli.
Authors claim this as the first structural imaging study to compare two subtypes of violent offenders.The structural defects could explain some of the core difficulties these individuals have.Authors raise the possibility that psychopathy is perhaps a neuro developmental disorder characterized by structural abnormalities from a young age.
