Neuroimaging studies of antisocial behaviour

Objective: To review recent neuroimaging studies of antisocial behaviour, including criminality, psychopathy, sexual offending, aggression, and violence. Method: Using OVID software, Psycinfo and Medline were searched for studies undertaken in the last 15 years. A brief outline of each technology is followed by a survey of published reports from refereed journals. Where indicated, critical appraisal is offered. Results: Converging evidence from multiple studies of structure and junction indicates that abnormal prefrontal (and probably subcortical) circuitry are very likely involved in antisocial behaviour. Conclusions: Clinicians should be aware of emerging findings from biological studies of antisociality. Future neuroimaging and other biologically based work, especially when combined with psychosocial initiatives, should yield fruit in attempts to better understand, treat, and prevent such socially devastating and destructive behaviour.
