Traumatic brain injury (TBI) can lead to significant post-traumatic disturbances
in mood and behavior, with the frontal lobes playing a key role in emotional and
behavioral regulation. Injury to the frontal lobe can result in disinhibition and
aggression which can result in police intervention and/or incarceration. We
highlight four adult cases with a history of severe TBI with frontal lobe
injuries and the presence of post-TBI criminal behaviors. There is evidence to
support an anatomical basis for aggressive behaviors, yet there are other risk
factors to be considered. Behaviors must be investigated thoroughly by obtaining
adequate pre- and post-TBI psychiatric and psychosocial histories. By having a
comprehensive understanding of aggression while appreciating the complex
relationship between TBI, aggression, and premorbid risk factors, clinicians can
more adequately treat patients with TBI, with the aim of potentially preventing
criminal behaviors and recidivism.
