While studying brain injuries in the mid-1990s, I began volunteering in a domestic violence shelter. I noticed that the abuse and problems many women reported were consistent with possibly experiencing concussions. Women reported many acts of violence that could cause trauma to the brain, as well as many post-concussive symptoms. Shockingly, my search for literature on this topic yielded zero results.
When I decided to focus my graduate work on this topic, I was even more shocked by what I learned from women who had experienced intimate partner violence (IPV). Of the 99 women I interviewed, 75% reported at least one traumatic brain injury (TBI) sustained from their partners and about half reported more than one — oftentimes many more than one. Also, as I predicted, the more brain injuries a woman reported, the more poorly she tended to perform on cognitive tasks such as learning and remembering a list of words. Additionally, having more brain injuries was associated with higher levels of psychological distress such as worry, depression, and anxiety.
When I published these results, I was excited about the possibility of bringing much-needed awareness and research attention to this topic. Unfortunately, over 20 years later — despite the plethora of concussion-related research in athletics and the military — concussion-related research in the context of intimate partner violence remains scant, representing a barely recognized and highly understudied public health epidemic.
What do we know about intimate partner violence-related traumatic brain injuries?
First, we need to understand that an estimated one in three women experience some type of physical or sexual partner violence in their lifetimes. IPV is not a rare event, and it traverses all socioeconomic boundaries. It is the number one cause of homicide for women and the number one cause of violence to women. For many reasons, including the stigma of being abused, many women hide their IPV — so the chances that we all know personally at least a few people who have sustained IPV are quite high.
Though we lack good epidemiological data on the number of women sustaining brain injuries from their partners, the limited data that we do have suggest that the numbers are in the millions in the US alone. Most of these TBIs are mild and are unacknowledged, untreated, and repetitive. Consequently, many women are at risk for persistent post-concussive syndrome with completely unknown longer-term health risks.
