growing number of studies suggest that neurocognitive deficits may also be relevant to the risk of aggression among people with schizophrenia [4145]. Neuroimaging and neu hological studies of violence in schizophrenia have been however mRed. Some studies suggest that schizophrenia patients with a history of aggression or violence demonstrate greater impairments in frontal functions particulary executive dysfunction and working memory limitations. Other studies suggest that although more impulsive violent offenders demonstrate better executive functioning and verbal skills and still others have found no differences [15,46-48]. It appears that a life-long history of antisocial behavior may moderate the association between neurocognition and violent behavior in schizophrenia given that violent offenders with antisociality prior to schizophrenia onset demonstrate better executive functioning and verbal skills (but poorer self-control) than non offenders [44,49]. Notwithstanding the role of antisociality or psychopathic traits, frontal deficits and neurological soft signs are present among offenders and non-offenders with schizophrenia that reduce their capacity to inhibit reactive aggression during provocations and other stressful situations. One study showed that violent offenders who demonstrated poor insight were even more impaired neurocognitively [50], which suggests that neurocognitive deficits may also influence the degree to which violent schizophrenia patients participate in treatment
