What imaging tells us about violence in anti-social men.
This paper provides an overview of imaging studies in samples of men with personality disorder (PD) who have been violent. Mention is also made of the work of two groups that have looked at the neural correlates of violence across diagnostic categories, including schizophrenia and anti-social PD given their relevance in the field. The paper focuses on the notion that aggressive behaviour can be conceptualised in terms of at least two types, reactive and pro-active, and that few studies separate them. The neuro-anatomical basis of aggression and associated neurobehavioural theories are discussed in relation to clinical disorders (mainly anti-social personality pathology) associated with these different types of aggressive behaviour. Structural (computed tomography, magnetic resonance imaging) and functional (positron emission tomography, fMRI, single-photon emission tomography) studies with violent people variously characterised as anti-social or having psychopathy will be critically reviewed.
