"Individuals with neuropsychological impairment as the result of a head injury are considered to be among those at greatest risk for developing violent and aggressive behavior. Sustaining a TBI [traumatic brain injury] has been found to be a significant predictor of becoming a batterer. In a comparison study, prior history of TBI was found to be more highly correlated with domestic battering than any other medical, psychosocial, and psychiatric variables measured (Cohen et al., 1999). Men with a history of brain injury are six times more likely to engage in spousal aggression, and in 93.1% of a group of batterers who sustained TBIs, the injury occurred prior to the first episode of domestic violence (Westby & Ferraro, 1999)."
