Domestic Violence Linked to Lasting Brain Injuries, Australian Study Finds
A groundbreaking Australian study has revealed compelling evidence that intimate partner violence can inflict long-term damage on the brain, leading to cognitive impairments such as memory loss and learning disabilities. The research, published in the Journal of Neurotrauma, underscores a critical need for increased awareness and specialized care for survivors of domestic violence.
A team at Monash University discovered that individuals who experienced repeated head impacts or non-fatal strangulation within abusive relationships exhibited significant behavioral and cognitive changes. These changes included impaired memory, the onset of seizures, and difficulties with speech. The findings draw a striking parallel to the well-documented link between repetitive concussions in professional sports and conditions like chronic traumatic encephalopathy (CTE).
“Essentially, what we found is that those with six or more brain injuries, head impacts or non-fatal strangulation had worse learning and memory outcomes than those who hadn’t experienced brain injuries from intimate partner violence,” explained a Monash University neuroscientist and lead author of the study. While not all participants met the clinical definition of impairment, a substantial number reported significant struggles with cognitive function.
The study revealed a particularly alarming statistic: 84.2% of participants who had sustained a brain injury due to intimate partner violence had experienced both non-fatal strangulation and a mild traumatic brain injury or concussion. This highlights the often-combined nature of abuse and the compounded risk to neurological health.
These findings build upon previous research. A 2018 study indicated that 40% of family violence victims presenting to Victorian hospitals over a decade had suffered a brain injury – a figure researchers believe is likely an underestimate due to underreporting. More recently, in 2024, Australia recorded its first cases of CTE diagnosed in two women whose conditions were linked to years of partner abuse.
Experts emphasize that the risks extend beyond the immediate physical trauma. A research fellow at the Australian Institute of Health Innovation, who has extensively studied sports concussions, noted that domestic violence survivors represent a significant at-risk group, alongside athletes and military veterans. “Literature from the sports field tells us that the cumulative impact of repeated trauma is associated with long-term health consequences like neurodegenerative diseases,” he stated. “There’s an increased risk of not just chronic traumatic encephalopathy, but also other forms of dementia.”
There is growing concern that the threshold for long-term brain damage may be lower than previously understood, and more difficult to measure. The prolonged nature of domestic violence, however, significantly elevates this risk. “If domestic violence is being perpetrated over time, that becomes an increased risk for the development of neurodegenerative disease,” the researcher added. “For those patients, referral to specialists with expertise in brain injury is critical. It’s not an issue that’s unique to the sporting population any more.”
Advocates are sounding the alarm about a critical gap in awareness and support. The chief executive of violence prevention organization No To Violence pointed out that women experiencing repeated concussions and strangulation through family violence are often less likely to be identified, diagnosed, or receive adequate support compared to athletes. “There is an enormous gap in awareness and understanding of the severe, often lifelong impacts these injuries have on victim-survivors’ memory, cognition, wellbeing and capacity to rebuild their lives,” he said. He stressed the importance of recognizing non-fatal strangulation as a particularly critical warning sign.
Ultimately, preventing these devastating harms requires a proactive approach focused on stopping violence at its source. “Preventing these devastating harms requires governments and communities to act decisively – identifying men’s use of violence earlier, responding consistently, and holding men accountable before patterns of coercive control escalate into repeated brain injury and life-threatening harm.”
