Strangulation, Domestic Violence, and Brain Injury: An Introduction to a Complex Topic

Categories: Living with Brain Injury, Research

By Jerrod Brown, Ph.D.

Affecting millions of individuals across the United States, intimate partner violence is the physical, sexual, or psychological harm of an individual by a romantic partner (Arroyo, Lundahl, Butters, Vanderloo, & Wood, 2017). Approximately one in four American women are the victims of severe physical violence perpetrated by their intimate partners at some point in their lifetime (Smith et al., 2017). Such intimate partner violence often takes the form of physical attacks including punching, shaking, hitting with an object, assaulting with a weapon, or near suffocation. The consequences of intimate partner violence can range from adverse physiological (e.g., broken bones and traumatic brain injuries) and mental health (e.g., post-traumatic stress disorder, depression, and anxiety) issues to homicide (Pritchard, Reckdenwald, & Nordham, 2017; Strack & Gwinn, 2011).

One particularly common yet destructive form of intimate partner violence is strangulation (Kwako, Glass, Campbell, Melvin, Barr, & Gill, 2011; Messing, Patch, Wilson, Kelen, & Campbell, 2018). Distinctly different than choking, strangulation is the application of pressure to the neck that restricts blood vessels and air passages. This in turn results in asphyxiation, or the restriction of oxygen, where oxygen fails to reach the brain and other parts of the body. It is thought that strangulation symbolizes the perpetrator’s control over the victim and demonstrates the perpetrator’s ability to kill the victim (Volochinsky, 2012).

There are two types of strangulation: manual and ligature. Manual strangulation is the process of using one’s hands or forearm to strangle the victim and may be the most common form of strangulation employed in the context of intimate partner violence. In contrast, ligature strangulation refers to the use of a rope, scarf, belt, or other similar object to strangle the victim (Volochinsky, 2012). Regardless of the type, strangulation may or may not be accompanied by visible symptoms of the injury.

Depending on length of time without oxygen, the victim may experience a loss of consciousness, potentially permanent medical consequences (e.g., strokes, brain injuries), and even death. In fact, victims of intimate partner violence who have experienced strangulation are much more likely to die as a result of intimate partner violence than those victims who do not experience strangulation. Even if the victims initially survive the strangulation, they may eventually die due to other complications. In these cases, victims die in the coming days or weeks after the strangulation as a result of blood clots, arterial complications, respiratory issues, or other reasons.

In the absence of death, brain injuries are often one of the most devastating and long-lasting consequences of strangulation. Victims of intimate partner violence may also experience traumatic brain injuries (TBIs) from blows to head and other assaults. (Prosser, Grigsby, & Pollock, 2018; Valera & Kucyi, 2017). Caused by open or closed injuries to the head, TBIs can be characterized as short- or long-term brain damage. This could include physical (e.g., loss of consciousness, headaches, and sleep disturbances), sensory (e.g., vision and auditory distortions and sensitivity to light and sound), cognitive (e.g., executive control and memory), and mental health (e.g., depression, anxiety, and mood fluctuations) symptoms. For a review of the injuries resulting from strangulation, please see Figure 1. As a result of these symptoms, individuals suffering from TBI could have difficulty functioning in daily life including performing regular tasks at home, school, or work.

The combination of psychological distress and brain injury can make it difficult to identify the presence of intimate partner violence. Specifically, the victims may have difficulty communicating the transpired events to authorities, physicians, and other professionals in a variety of contexts. For example, this could occur in conversations with police officers during criminal investigations or with mental health care providers during psychological assessments. The causes of communication difficulties may include short- and long-term memory impairments, post-traumatic stress disorder symptoms, or other intimate partner violence sequelae. The practical consequences of communication difficulties are the under-identification of intimate partner violence victimization. As a result, the individual may be (a) exposed to further intimate partner violence in community settings, (b) viewed as an unreliable source of information in criminal justice and legal settings, and (c) undiagnosed or misdiagnosed in psychiatric settings.

To improve the identification of survivors of intimate partner violence, professionals must adopt advanced methods of screening and assessment (Pritchard, Reckdenwald, Nordham, & Holton, 2018). One consideration should be the manner in which screening and assessments are conducted. Specifically, interactions with clients should be characterized by slow pace, repetition, checks for comprehension, and frequent breaks. Beyond this, professionals should specifically screen for both intimate partner violence victimization and brain injury. This could involve questions about concussions, blackouts, and loss of consciousness. Failure to adopt these suggestions and approaches may result in symptoms being misattributed to other ailments, misdiagnosis, and ultimately inappropriate and ineffective interventions.

A lack of recognition of the links between intimate partner violence, strangulation, and brain injury translates to under-treatment. This is troubling because timely intervention is essential in the minimization of negative short- and long-term outcomes. When untreated, brain injuries can worsen over time and have permanent consequences on the victim’s global functioning along with tremendous societal costs. As such, it is essential that the potential TBIs be evaluated by a physician with referrals to appropriate treatment services as soon as possible.

In instances where professionals lack expertise in brain injury, it may be fruitful to call on the assistance of specialists. Those with expertise can help ensure the client has not only been adequately assessed and diagnosed, but also provide guidance in the development of the course of treatment. This should include a discussion of how to address the client’s individualized needs throughout treatment with appropriate services and techniques. Further, professionals with expertise must also assist in the safety planning process. Such plans should clearly identify ways to minimize the risk of intimate partner violence and TBI along with safe places where the victim can receive treatment and recover from injuries (Murray, Lundgren, Olson, & Hunnicutt, 2016).

In light of the serious consequences reviewed in this article, there is an immediate and ongoing need for increased awareness of intimate partner violence and brain injury. This includes professionals working in law enforcement, forensic, criminal justice, mental health, medical, and social service settings. An essential path forward includes improving the accessibility of these professionals to education and training programs on the areas of intimate partner violence and brain injury, particularly programs that explore the intersectionality of these topics. In addition to broadening awareness, law enforcement agencies and organizations that serve survivors of intimate partner violence should adopt universal screening procedures for identifying brain injury. Any individual identified with potential brain injuries must be strongly encouraged to receive a thorough assessment and any necessary treatment.
