A global collaboration to study intimate partner violence-related head trauma: The ENIGMA consortium IPV working group.

Intimate partner violence includes psychological aggression, physical violence, sexual violence, and stalking from a current or former intimate partner. Past research suggests that exposure to intimate partner violence can impact cognitive and psychological functioning, as well as neurological outcomes. These seem to be compounded in those who suffer a brain injury as a result of trauma to the head, neck or body due to physical and/or sexual violence. However, our understanding of the neurobehavioral and neurobiological effects of head trauma in this population is limited due to factors including difficulty in accessing/recruiting participants, heterogeneity of samples, and premorbid and comorbid factors that impact outcomes. Thus, the goal of the Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA) Consortium Intimate Partner Violence Working Group is to develop a global collaboration that includes researchers, clinicians, and other key community stakeholders. Participation in the working group can include collecting harmonized data, providing data for meta- and mega-analysis across sites, or stakeholder insight on key clinical research questions, promoting safety, participant recruitment and referral to support services. Further, to facilitate the mega-analysis of data across sites within the working group, we provide suggestions for behavioral surveys, cognitive tests, neuroimaging parameters, and genetics that could be used by investigators in the early stages of study design. We anticipate that the harmonization of measures across sites within the working group prior to data collection could increase the statistical power in characterizing how intimate partner violence-related head trauma impacts long-term physical, cognitive, and psychological health.

Traumatic Brain Injury in Domestic Violence Victims: A Retrospective Study at the Barrow Neurological Institute.

Domestic violence is a national health crisis, which affects people of all ages, races, and socioeconomic classes. Traumatic brain injury is common in victims because of the high frequency of head and neck injuries inflicted through abuse. These recurrent injuries can lead to chronic symptoms with high morbidity. We conducted a retrospective chart review of 115 patients with a history of head trauma as a result of domestic violence. All patients were seen in a subspecialty traumatic brain injury clinic, at which time information regarding their histories and self-reported symptoms were recorded. In total, 109 females and 6 males were included in our study, with an age range of 4-68 years. Overall, 88% reported more than one injury and 81% reported a history of loss of consciousness associated with their injuries. Only 21% sought medical help at the time of injury. Whereas 85% had a history of abuse in adulthood, 22% had experienced abuse in both childhood and adulthood, and 60% of the patients abused as children went on to be abused as adults. Headache was the most common chief complaint, but on a self-reported symptom severity scale, behavioral symptoms were the most severe. Psychiatric disease was present in 84% of patients. Traumatic brain injury is a frequent sequela of domestic violence, from which many victims sustain multiple injuries without seeking medical care. Brain injuries are often sustained over many years and lead to lasting physical, behavioral, and cognitive consequences. Better understanding of these injuries will lead to improved care for this population.
