Traumatic Brain Injury and Antisocial Behavior: An Underestimated Connection
Year: 2025
Type: article
Abstract: Traumatic brain injury (TBI) represents a critical yet underappreciated determinant of antisocial behavior and criminal conduct. This comprehensive review synthesizes neurobiological mechanisms linking brain trauma to behavioral disinhibition, emphasizing frontal lobe dysfunction and its cascading effects on executive control, impulse regulation, and moral reasoning. Epidemiological evidence reveals strikingly elevated TBI rates among incarcerated populations -ranging from 25% to 87% - compared to 8.5% in the general population. Neuroimaging and neuropsychological investigations demonstrate that prefrontal cortical damage, particularly in orbitofrontal and ventromedial regions, disrupts neural circuits essential for behavioral control and social cognition. Clinical case studies of acquired antisocial behavior following brain injury provide compelling evidence for direct causal relationships. These findings challenge traditional criminal justice paradigms while highlighting the urgent need for specialized rehabilitation approaches that address underlying neurobiological dysfunction. This narrative review examines current evidence on TBI-antisocial behavior connections and explores the complex intersection of neurobiology, personal responsibility, and societal responses to crime.
