Strangulation in Domestic Violence: What Clinicians, Advocates, and Survivors Need to Know

By Melissa Roark, MA, LPCC | April 2nd, 2026

Of all the forms of violence that occur within abusive relationships, strangulation is one of the most dangerous, most misunderstood, and most under-reported. It is often dismissed — by survivors, bystanders, and even first responders — because it so frequently leaves no visible mark. Yet the absence of visible injury does not mean the absence of harm. Strangulation is a medical emergency, a serious crime, and one of the strongest predictors of future homicide in domestic violence relationships. Understanding it fully is not optional for those who work with survivors — it is a clinical and ethical imperative.

Choking vs. Strangulation: Why the Words Matter

The terms "choking" and "strangulation" are used interchangeably in everyday language — but in medical, legal, and advocacy contexts, they describe two entirely different events. Choking occurs internally, when a foreign object lodges in the throat and blocks the airway from within. Strangulation occurs externally, when pressure applied to the neck impedes breathing and/or the circulation of blood to and from the brain (Glenn, 2020).

This distinction carries profound legal consequences. Strangulation can be criminally prosecuted; choking cannot. When a survivor, witness, or even a law enforcement officer uses the word "choking" to describe what was actually strangulation, a defense attorney may exploit that language to undermine the case. Clinicians and advocates should use precise language — and gently help survivors adopt it as well. “She was strangled.” “He strangled her.” “She was placed in a stranglehold.” The words we choose can affect whether an abuser faces accountability (Glenn, 2020).

How Serious Is It? The Lethality Data

Strangulation is not just a form of violence — it is a declaration of lethal intent. Unconsciousness can occur within six seconds, brain damage follows quickly, and death can occur within one to two minutes (Glenn, 2020). According to the Training Institute on Strangulation Prevention, a woman who has experienced a nonfatal strangulation by an intimate partner is 750% more likely to be killed by that same partner — often with a gun (Ketchmark, 2020). Research further shows that in studies of intimate partner homicide victims, 43% had experienced nonfatal strangulation by their partner prior to being murdered, and in attempted homicide cases, 45% of victims had previously been strangled (Domestic Shelters, 2024).

Among women who experience intimate partner violence, research suggests that up to 68% will experience near-fatal strangulation at some point in the relationship (Naples Shelter, 2024). Despite these numbers, strangulation remains one of the least documented and least prosecuted forms of domestic violence — in large part because only about half of strangulation victims have any visible injuries, and only 15% have injuries that can be photographed (STM Learning, 2022). The absence of a bruise does not mean the absence of a crime.

Two Forms of Strangulation

Strangulation in domestic violence takes two primary forms. Manual strangulation involves the use of hands, arms, or other body parts to apply pressure to the neck. Ligature strangulation involves an external object — a cord, rope, bedsheet, or similar item — used to compress the airway or blood vessels. Hanging is classified as a variant of ligature strangulation. Both forms carry serious risk of immediate and long-term harm, regardless of whether physical evidence is visible at the time of assessment (Field, 2019).

Recognizing the Signs: A Symptom-by-Symptom Guide

Because strangulation so often leaves no external mark, clinicians and advocates must be trained to identify it through reported symptoms. The Training Institute on Strangulation Prevention identifies the following categories of signs, each corresponding to specific neurological and physiological damage (Brown, 2019):

Voice and swallowing changes: A raspy or hoarse voice, difficulty or pain when swallowing, nausea, drooling, or complete loss of voice may indicate damage to the neck muscles, Broca's and Wernicke's areas, the medulla oblongata, and the temporal lobe.

Hearing and breathing changes: Ringing, buzzing, pressure, or loss of hearing may signal damage to the temporal lobe and auditory cortex. Difficulty breathing or hyperventilation may reflect damage to the brainstem, including the medulla oblongata and pons.

Vision changes: "Seeing stars," blurry vision, darkness around the edges, or complete vision loss can indicate damage to the occipital lobe and primary visual cortex.

Behavioral and cognitive changes: Restlessness, agitation, difficulty concentrating, amnesia, hallucinations, or PTSD symptoms may reflect frontal lobe or limbic system damage.

Other changes: Memory loss, dizziness, headaches, involuntary urination or defecation, and loss of strength may suggest brainstem damage. Critically, these symptoms can appear hours or even days after the strangulation event — making continuous monitoring essential for survivors entering shelter or clinical care (Brown, 2019).

The Clinical Reality: Strangulation as Traumatic Brain Injury

Strangulation cuts off the blood vessels that deliver oxygen to the brain. Even a brief episode can result in a Traumatic Brain Injury (TBI) with lasting neurological and cognitive consequences. For clinicians, this is not an abstract concern — it directly affects how survivors present in session, how they recall events, and what treatment approaches will be most effective.

Cognitive impairments from TBI can make it genuinely difficult for survivors to clearly recount domestic violence events — in therapy, in safety planning conversations, and in court. Neurological impairments may affect daily functioning so profoundly that some survivors will require lifelong supportive services. When a clinician becomes aware of a history of strangulation during treatment, the appropriate response is to sincerely encourage the client to pursue neurological imaging to rule out medical contributors to their mental health presentation, and to adjust diagnostic and treatment planning accordingly (Kwako et al., 2011). A strangulation history should be incorporated into the intake and diagnostic assessment process — not treated as a footnote.

Legal Implications and the Advocate's Role

Under Ohio law, strangulation is defined as intentionally impeding the normal breathing or circulation of blood by applying pressure on the throat or neck, or by blocking the nose or mouth, in a manner that creates a risk of death or substantial bodily harm (Ohio Revised Code). Across the United States, at least 45 states have enacted specific criminal statutes addressing strangulation, with many classifying it as a felony. In Ohio, strangulation in the context of domestic violence carries serious criminal penalties.

For advocates and therapists, educating survivors — and ourselves — about the distinction between choking and strangulation, the legal weight of that distinction, and the medical urgency of any strangulation event is part of effective, life-saving advocacy. Strangulation screening should be added to the intake process. Medical attention should be strongly encouraged any time strangulation is disclosed, even if the survivor reports feeling fine. Symptoms can be delayed. Serious injuries — including carotid dissections, strokes, and blood clots — can develop with no immediate external evidence (Brown, 2019; Prosser et al., 2018).

What We Do With This Knowledge

Strangulation is not a minor incident that happened to leave no mark. It is one of the most terrifying, physically dangerous, and lethality-predictive events that can occur in a domestic violence relationship. When a survivor discloses that their partner "choked" them, the response from clinicians and advocates must be immediate, trauma-informed, and medically informed. Ask specific follow-up questions. Use accurate language. Encourage medical evaluation. Document thoroughly. And understand that the person in front of you may be carrying neurological damage they are not even aware of.

The faster we recognize and respond to strangulation, the more we can mitigate its impact — and potentially save a life. Knowledge is not just power in this context. It is protection.
