Neurobiological Bases of Aggression and Related Neuropsychological Deficits in Violent Criminal and Forensic Populations

[Speaker] Nussbaum, David:1

Crime and especially violent crime is a major global problem. This talk will present a broad literature review of published empirical studies demonstrating the high prevalence of executive function and other neuropsychological deficits in criminal populations. Next, a neurobiological-based aggression typology will be presented, with specific neuroanatomical and explanatory neuropsychological deficits linked to a) Predatory/Instrumental, b) Irritable/Anger-Based, and c) Defensive/Fear-Based aggression types. Existing neuropsychological methods for assessing ventromedial, orbital and dorsolateral regulatory deficits will be described. Supportive empirical data will then be presented. Implications for electrophysiological assessment refinements and implications for individually designed interventions and change monitoring will be discussed.
