Mild traumatic brain injury (mTBI) can result in many adverse outcomes, including cognitive deficits, behavioral challenges, and social and communication impairments. Post-concussion syndrome (PCS) refers to TBI symptoms that persist beyond the expected recovery period. PCS can include irritability, difficulty concentrating, and memory problems that can negatively influence emotional regulation, social skills, and interpersonal relationships. These effects of PCS may also contribute to an increased risk of perpetrating intimate partner violence.
While previous research in this field has focused on the development of PCS following traumatic events in combat veterans, little research has examined the possible impact of PCS on the perpetration of intimate partner violence. A team of researchers recruited 827 veterans who experienced an mTBI to determine the prevalence and severity of both PCS and intimate partner violence (controlling for common risk factors for intimate partner violence, such as substance abuse).
The researchers found that those who experienced PCS after mTBI were more likely to perpetrate intimate partner violence than those who did not. PCS elevated risk of intimate partner violence more than any other risk factor including post-traumatic stress disorder, pain, and substance use. Among the veteran population with an mTBI, married individuals were significantly more likely to report intimate partnership violence perpetration than unmarried individuals.
