Traumatic brain injury produces a variety of cognitive effects.
Some individuals will have behavioral disturbances including anger outbursts and interpersonal conflict.
A recent study examined the rates of first criminal conviction in a group of 7694 men and women hospitalized with traumatic brain injury (TBI).
The study found about a 50 to 75% increase in rates of post-TBI criminal convictions including violent convictions. This effect was noted using either general population controls or sibling controls.
