Violence against women and acquired brain injuries

, , , , , , ,

Violence against women and resulting traumatic brain injuries increased during the COVID-19 pandemic.

Violence against women, which can result in traumatic brain injury (TBI) and other acquired brain injuries (ABIs), intensified during the COVID-19 pandemic. A comprehensive and long-term strategy is required to address this issue and to ensure the mental well-being of women.

The Case of Gabby Petito

In July 2021, social media influencer Gabby Petito and her fiancé, Brian Laundrie, embarked on a cross-country road trip captured on Instagram and YouTube.1 In September, Laundrie returned—alone. Weeks later, Petito’s remains were found. It was determined that she died from strangulation, and her case opened a national conversation about intimate partner violence (IPV).2

Tragically, Petito’s case is just 1 of many. There has been an increase in IPV, illuminating a shadow pandemic within the COVID-19 pandemic.3,4 Even before COVID-19, 1 in 3 women (approximately 1.27 billion women worldwide) experienced IPV.5 Further, more than one-third (30,000) of the women killed in 2017 in the US died at the hands of their current or former intimate partner.6 In 2020, calls to helplines increased 5-fold in some countries.4 In some nations, there has been a 300% increase in police reports of IPV, likely fueled by COVID-19 mitigation strategies.4 UN Women projected that an additional 15 million women would be affected by IPV for every 3 months of lockdown.7

The neurological consequences and IPV-related ABIs, including TBI, are devastating. Despite recent increased focus on sports-related TBI, little attention has been paid to TBI resulting from IPV.8 Yet, up to 90% of IPV survivors report head, neck, and facial injuries, which can result in TBI.9,10 One study found that 74% of the women who experienced IPV sustained at least 1 IPV-related TBI and 51% suffered repetitive IPV-related TBIs.11 The study also found higher brain injury scores were negatively associated with memory, learning, and cognitive flexibility and positively associated with a number of measures of psychological distress.11

IPV-related ABI also includes nontraumatic brain injuries. Research has shown that 1 in 10 women has been choked by an intimate partner,12 which can cause hypoxic-anoxic brain injury with long-term implications. Plus, prior nonfatal strangulation has been associated with greater than 6-fold odds of becoming a victim of attempted homicide and more than 7-fold odds of becoming a victim of completed homicide.13 The high-profile strangulation homicide of Petito underscores femicide in IPV, which remains commonplace.2

After the Violence Has Ended

In addition, women who experience IPV also are more likely to suffer from anxiety, depression, posttraumatic stress disorder, suicidal ideation, and other health problems that can last after the violence has ended.4,14

There is also concern that repeated TBIs from IPV may result in chronic traumatic encephalopathy (CTE), a progressive and fatal neurodegenerative disease that cannot be diagnosed until postmortem.8,15-18 For instance, a 1990 report identified a case of a woman who apparently developed CTE from partner abuse.19 In 2021, during a postmortem examination of a young woman who died after a domestic violence incident, immunohistochemical staining for phosphor-τ revealed evidence of CTE-type pathology.20 This marked the first case of CTE pathology in a young woman who experienced IPV. However, there remains a lack of research investigating the long-term neurological consequences; research is needed to understand the potential for misdiagnosis, nondiagnosis, or the development of dementia and Alzheimer disease due to IPV.15,21 The latter is especially important because TBI has been identified as a modifiable risk factor for dementia.22

Current Research

The neurological effects of IPV extend to the family and remain underresearched. A recent Brain Injury Australia report found that of 16,000 survivors of family violence attending Victoria hospitals over a decade’s time, 2 in every 5 had suffered brain injury.23 Further, nearly 1 in 3 of the survivors of family violence were children; of those, 1 in 4 had suffered a brain injury. Because this was not a study of IPV but of hospitalizations, it likely represents the tip of the iceberg. Another study across 5 domestic abuse shelters in Arizona found 9 in every 10 individuals reported a head injury with loss of consciousness from family violence in the preceding 12 months.24 Of those, 9 in 10 reported “too many head injuries to quantify.” Yet only 1 in 5 ever sought medical attention. Thus, community rates of IPV ABI remain radically underresearched.

Most domestic violence shelters and emergency department settings do not assess for TBI, nonfatal strangulation, or other brain injuries from IPV.13,15,25 Plus, many women do not seek medical care for their IPV-related ABI.26 However, even when women interact with health care and domestic violence advocates, there is a lack of training to adequately screen for and address IPV-related ABI.7,23

Further, a study of women in prison found that 78% had significant head injury; 84% had experienced repeated head injury largely due to domestic abuse.27 Yet screening and care for brain injury are not adequately accounted for in the criminal justice system. The staggering number of women who have experienced abuse and are now in prison also further necessitates development of a trauma-informed criminal justice system.

The Brain Health Gap & Brain Capital

IPV-related ABI adds yet another injustice to the brain health gap, which highlights and frames the sex and gender gap in outcomes for brain health disorders across the life span, with strikingly negative outcomes for women.28,29 Research institutions are calling for more female participants in preclinical development of medications, clinical trials, and clinical practice, as well as the expansion of research designed to focus on culturally relevant experiences specific to individuals who identify as female. This will enable collection of more robust and representative data. Big data, real-world evidence, and precision medicine approaches should be used to respond to the call to action. Furthermore, investing in public health efforts is imperative to translate these data and perspectives into action. Women remain underrepresented in health care leadership, underlining the lack of gendered consideration in care. These efforts and initiatives are especially important for research, clinical care, and training related to IPV.

Likewise, the world is suffering a global brain capital collapse.30-32 Brain capital is a novel econometric asset that puts a premium on brain health and skills in our brain economy.30,31 This is a form of capital relevant to a complex, interconnected, and fragile global economy. Brain capital needs to be integral to a new narrative of growth and progress that puts individuals and their well-being, health, interaction with others, and psychological resilience at the center of our economic system. Female empowerment—which includes preventing and addressing violence against women and better identifying and caring for the neurological effects in survivors—is a public and brain health imperative as well as the most effective way to build brain capital globally.

Concluding Thoughts

Addressing gendered violence and related ABIs can be remedied by integrating the social, medical, political, policy, and diplomatic levels. Taking sex and gender into account—including structural and social determinants—is critical for equality in brain health and precision medicine. The Organisation for Economic Co-operation and Development (OECD) New Approaches to Economic Challenges Unit’s Neuroscience-inspired Policy Initiative (NIPI) seeks to tackle this issue.30,31,33 We aim to find new ways to reconceptualize and revitalize the economy and how it works, laying the groundwork to identify relevant metrics while building a transdisciplinary network of stakeholders. The effort draws on experts from medicine, neuroscience, gender analysis, economic policy, philanthropy, and business. The initiative will rapidly refine and advance women’s brain health via a series of research projects, seminars, and clear policy analyses and recommendations. We hope to help build a future in which al individuals are equipped with the support, resources, and care they need to thrive and in turn build a more resilient society and world.
