The Body Keeps the Score

by Bessel van der Kolk MD

  I have extensively interviewed and treated six people who survived plane crashes. Two reported having lost consciousness during the incident; even though they were not physically injured, they collapsed mentally. Two went into a panic and stayed frantic until well after we had started treatment. Two remained calm and resourceful and helped evacuate fellow passengers from the burning wreckage. I’ve found a similar range of responses in survivors of rape, car crashes, and torture. In the previous chapter we saw the radically different reactions of Stan and Ute as they relived the highway disaster they’d experienced side by side. What accounts for this spectrum of responses: focused, collapsed, or frantic?

  Porges’s theory provides an explanation: The autonomic nervous system regulates three fundamental physiological states. The level of safety determines which one of these is activated at any particular time. Whenever we feel threatened, we instinctively turn to the first level, social engagement. We call out for help, support, and comfort from the people around us. But if no one comes to our aid, or we’re in immediate danger, the organism reverts to a more primitive way to survive: fight or flight. We fight off our attacker, or we run to a safe place. However, if this fails—we can’t get away, we’re held down or trapped—the organism tries to preserve itself by shutting down and expending as little energy as possible. We are then in a state of freeze or collapse.

  This is where the many-branched vagus nerve comes in, and I’ll describe its anatomy briefly because it’s central to understanding how people deal with trauma. The social-engagement system depends on nerves that have their origin in the brain stem regulatory centers, primarily the vagus—also known as the tenth cranial nerve—together with adjoining nerves that activate the muscles of the face, throat, middle ear, and voice box or larynx. When the “ventral vagal complex” (VVC) runs the show, we smile when others smile at us, we nod our heads when we agree, and we frown when friends tell us of their misfortunes. When the VVC is engaged, it also sends signals down to our heart and lungs, slowing down our heart rate and increasing the depth of breathing. As a result, we feel calm and relaxed, centered, or pleasurably aroused.

  The many-branched vagus. The vagus nerve (which Darwin called the pneumogastric nerve) registers heartbreak and gut-wrenching feelings. When a person becomes upset, the throat gets dry, the voice becomes tense, the heart speeds up, and respiration becomes rapid and shallow.

  Three responses to threat.

  1.The social engagement system: an alarmed monkey signals danger and calls for help. VVC.

  2.Fight or flight: Teeth bared, the face of rage and terror. SNS.

  3.Collapse: The body signals defeat and withdraws. DVC.

  Any threat to our safety or social connections triggers changes in the areas innervated by the VVC. When something distressing happens, we automatically signal our upset in our facial expressions and tone of voice, changes meant to beckon others to come to our assistance.11 However, if no one responds to our call for help, the threat increases, and the older limbic brain jumps in. The sympathetic nervous system takes over, mobilizing muscles, heart, and lungs for fight or flight.12 Our voice becomes faster and more strident and our heart starts pumping faster. If a dog is in the room, she will stir and growl, because she can smell the activation of our sweat glands.

  Finally, if there’s no way out, and there’s nothing we can do to stave off the inevitable, we will activate the ultimate emergency system: the dorsal vagal complex (DVC). This system reaches down below the diaphragm to the stomach, kidneys, and intestines and drastically reduces metabolism throughout the body. Heart rate plunges (we feel our heart “drop”), we can’t breathe, and our gut stops working or empties (literally “scaring the shit out of” us). This is the point at which we disengage, collapse, and freeze.

  FIGHT OR FLIGHT VERSUS COLLAPSE

  As we saw in Stan’s and Ute’s brain scans, trauma is expressed not only as fight or flight but also as shutting down and failing to engage in the present. A different level of brain activity is involved for each response: the mammalian fight-or-flight system, which is protective and keeps us from shutting down, and the reptilian brain, which produces the collapse response. You can see the difference between these two systems at any big pet store. Kittens, puppies, mice and gerbils constantly play around, and when they’re tired they huddle together, skin to skin, in a pile. In contrast, the snakes and lizards lie motionless in the corners of their cages, unresponsive to the environment.13 This sort of immobilization, generated by the reptilian brain, characterizes many chronically traumatized people, as opposed to the mammalian panic and rage that make more recent trauma survivors so frightened and frightening.

  Almost everyone knows what that quintessential fight/flight response, road rage, feels like: A sudden threat precipitates an intense impulse to move and attack. Danger turns off our social-engagement system, decreases our responsiveness to the human voice, and increases our sensitivity to threatening sounds. Yet for many people panic and rage are preferable to the opposite: shutting down and becoming dead to the world. Activating flight/flight at least makes them feel energized. That is why so many abused and traumatized people feel fully alive in the face of actual danger, while they go numb in situations that are more complex but objectively safe, like birthday parties or family dinners.

  When fighting or running does not take care of the threat, we activate the last resort—the reptilian brain, the ultimate emergency system. This system is most likely to engage when we are physically immobilized, as when we are pinned down by an attacker or when a child has no escape from a terrifying caregiver. Collapse and disengagement are controlled by the DVC, an evolutionarily ancient part of the parasympathetic nervous system that is associated with digestive symptoms like diarrhea and nausea. It also slows down the heart and induces shallow breathing. Once this system takes over, other people, and we ourselves, cease to matter. Awareness is shut down, and we may no longer even register physical pain.

  HOW WE BECOME HUMAN

  In Porges’s grand theory the VVC evolved in mammals to support an increasingly complex social life. All mammals, including human beings, band together to mate, nurture their young, defend against common enemies, and coordinate hunting and food acquisition. The more efficiently the VVC synchronizes the activity of the sympathetic and parasympathetic nervous systems, the better the physiology of each individual will be attuned to that of other members of the tribe.

  Thinking about the VVC in this way illuminates how parents naturally help their kids to regulate themselves. Newborn babies are not very social; they sleep most of the time and wake up when they’re hungry or wet. After having been fed they may spend a little time looking around, fussing, or staring, but they will soon be asleep again, following their own internal rhythms. Early in life they are pretty much at the mercy of the alternating tides of their sympathetic and parasympathetic nervous systems, and their reptilian brain runs most of the show.

  But day by day, as we coo and smile and cluck at them, we stimulate the growth of synchronicity in the developing VVC. These interactions help to bring our babies’ emotional arousal systems into sync with their surroundings. The VVC controls sucking, swallowing, facial expression, and the sounds produced by the larynx. When these functions are stimulated in an infant, they are accompanied by a sense of pleasure and safety, which helps create the foundation for all future social behavior.14 As my friend Ed Tronick taught me a long time ago, the brain is a cultural organ—experience shapes the brain.

  Being in tune with other members of our species via the VVC is enormously rewarding. What begins as the attuned play of mother and child continues with the rhythmicity of a good basketball game, the synchrony of tango dancing, and the harmony of choral singing or playing a piece of jazz or chamber music—all of which foster a deep sense of pleasure and connection.

 
We can speak of trauma when that system fails: when you beg for your life, but the assailant ignores your pleas; when you are a terrified child lying in bed, hearing your mother scream as her boyfriend beats her up; when you see your buddy trapped under a piece of metal that you’re not strong enough to lift; when you want to push away the priest who is abusing you, but you’re afraid you’ll be punished. Immobilization is at the root of most traumas. When that occurs the DVC is likely to take over: Your heart slows down, your breathing becomes shallow, and, zombielike, you lose touch with yourself and your surroundings. You dissociate, faint and collapse.

  DEFEND OR RELAX?

  Steve Porges helped me realize that the natural state of mammals is to be somewhat on guard. However, in order to feel emotionally close to another human being, our defensive system must temporarily shut down. In order to play, mate, and nurture our young, the brain needs to turn off its natural vigilance.

  Many traumatized individuals are too hypervigilant to enjoy the ordinary pleasures that life has to offer, while others are too numb to absorb new experiences—or to be alert to signs of real danger. When the smoke detectors of the brain malfunction, people no longer run when they should be trying to escape or fight back when they should be defending themselves. The landmark ACE (Adverse Childhood Experiences) study, which I’ll discuss in more detail in chapter 9, showed that women who had an early history of abuse and neglect were seven times more likely to be raped in adulthood. Women who, as children, had witnessed their mothers being assaulted by their partners had a vastly increased chance to fall victim to domestic violence.15

  Many people feel safe as long as they can limit their social contact to superficial conversations, but actual physical contact can trigger intense reactions. However, as Porges points out, achieving any sort of deep intimacy—a close embrace, sleeping with a mate, and sex—requires allowing oneself to experience immobilization without fear.16 It is especially challenging for traumatized people to discern when they are actually safe and to be able to activate their defenses when they are in danger. This requires having experiences that can restore the sense of physical safety, a topic to which we’ll return many times in the chapters that follow.

  NEW APPROACHES TO TREATMENT

  If we understand that traumatized children and adults get stuck in fight/flight or in chronic shut-down, how do we help them to deactivate these defensive maneuvers that once ensured their survival?

  Some gifted people who work with trauma survivors know how to do this intuitively. Steve Gross used to run the play program at the Trauma Center. Steve often walked around the clinic with a brightly colored beach ball, and when he saw angry or frozen kids in the waiting room, he would flash them a big smile. The kids rarely responded. Then, a little later, he would return and “accidentally” drop his ball close to where a kid was sitting. As Steve leaned over to pick it up, he’d nudge it gently toward the kid, who’d usually give a halfhearted push in return. Gradually Steve got a back-and-forth going, and before long you’d see smiles on both faces.

  From simple, rhythmically attuned movements, Steve had created a small, safe place where the social-engagement system could begin to reemerge. In the same way, severely traumatized people may get more out of simply helping to arrange chairs before a meeting or joining others in tapping out a musical rhythm on the chair seats than they would from sitting in those same chairs and discussing the failures in their life.

  One thing is certain: Yelling at someone who is already out of control can only lead to further dysregulation. Just as your dog cowers if you shout and wags his tail when you speak in a high singsong, we humans respond to harsh voices with fear, anger, or shutdown and to playful tones by opening up and relaxing. We simply cannot help but respond to these indicators of safety or danger.

  Sadly, our educational system, as well as many of the methods that profess to treat trauma, tend to bypass this emotional-engagement system and focus instead on recruiting the cognitive capacities of the mind. Despite the well-documented effects of anger, fear, and anxiety on the ability to reason, many programs continue to ignore the need to engage the safety system of the brain before trying to promote new ways of thinking. The last things that should be cut from school schedules are chorus, physical education, recess, and anything else involving movement, play, and joyful engagement. When children are oppositional, defensive, numbed out, or enraged, it’s also important to recognize that such “bad behavior” may repeat action patterns that were established to survive serious threats, even if they are intensely upsetting or off-putting.

  Porges’s work has had a profound effect on how my Trauma Center colleagues and I organize the treatment of abused children and traumatized adults. It’s true that we would probably have developed a therapeutic yoga program for women at some point, given that yoga had proved so successful in helping them calm down and get in touch with their dissociated bodies. We would also have been likely to experiment with a theater program in the Boston inner-city schools, with a karate program for rape survivors called impact model mugging, and with play techniques and body modalities like sensory stimulation that have now been used with survivors around the world. (All of these and more will be explored in part 5.)

  But the polyvagal theory helped us understand and explain why all these disparate, unconventional techniques worked so well. It enabled us to become more conscious of combining top-down approaches (to activate social engagement) with bottom-up methods (to calm the physical tensions in the body). We were more open to the value of other age-old, nonpharmacological approaches to health that have long been practiced outside Western medicine, ranging from breath exercises (pranayama) and chanting to martial arts like qigong to drumming and group singing and dancing. All rely on interpersonal rhythms, visceral awareness, and vocal and facial communication, which help shift people out of fight/flight states, reorganize their perception of danger, and increase their capacity to manage relationships.

  The body keeps the score:17 If the memory of trauma is encoded in the viscera, in heartbreaking and gut-wrenching emotions, in autoimmune disorders and skeletal/muscular problems, and if mind/brain/visceral communication is the royal road to emotion regulation, this demands a radical shift in our therapeutic assumptions.

  CHAPTER 6

  LOSING YOUR BODY, LOSING YOUR SELF

  Be patient toward all that is unsolved in your heart and try to love the questions themselves. . . . Live the questions now. Perhaps you will gradually, without noticing it, live along some distant day into the answer.

  —Rainer Maria Rilke, Letters to a Young Poet

  Sherry walked into my office with her shoulders slumped, her chin nearly touching her chest. Even before we spoke a word, her body was telling me that she was afraid to face the world. I also noticed that her long sleeves only partially covered the scabs on her forearms. After sitting down, she told me in a high-pitched monotone that she couldn’t stop herself from picking at the skin on her arms and chest until she bled.

  As far back as Sherry could remember, her mother had run a foster home, and their house was often packed with as many as fifteen strange, disruptive, frightened, and frightening kids who disappeared as suddenly as they arrived. Sherry had grown up taking care of these transient children, feeling that there was no room for her and her needs. “I know I wasn’t wanted,” she told me. “I’m not sure when I first realized that, but I’ve thought about things that my mother said to me, and the signs were always there. She’d tell me, ‘You know, I don’t think you belong in this family. I think they gave us the wrong baby.’ And she’d say it with a smile on her face. But, of course, people often pretend to joke when they say something serious.”

  Over the years our research team has repeatedly found that chronic emotional abuse and neglect can be just as devastating as physical abuse and sexual molestation.1 Sherry turned out to be a living example of these findings: Not being seen, not being known, and having nowhe
re to turn to feel safe is devastating at any age, but it is particularly destructive for young children, who are still trying to find their place in the world.

  Sherry had graduated from college, but she now worked in a joyless clerical job, lived alone with her cats, and had no close friends. When I asked her about men, she told me that her only “relationship” had been with a man who’d kidnapped her while she was on a college vacation in Florida. He’d held her captive and raped her repeatedly for five consecutive days. She remembered having been curled up, terrified and frozen for most of that time, until she realized she could try to get away. She escaped by simply walking out while he was in the bathroom. When she called her mother collect for help, her mother refused to take the call. Sherry finally managed to get home with assistance from a domestic violence shelter.

  Sherry told me that she’d started to pick at her skin because it gave her some relief from feeling numb. The physical sensations made her feel more alive but also deeply ashamed—she knew she was addicted to these actions but could not stop them. She’d consulted many mental health professionals before me and had been questioned repeatedly about her “suicidal behavior.” She’d also been subjected to involuntary hospitalization by a psychiatrist who refused to treat her unless she could promise that she would never pick at herself again. However, in my experience, patients who cut themselves or pick at their skin like Sherry, are seldom suicidal but are trying to make themselves feel better in the only way they know.

  This is a difficult concept for many people to understand. As I discussed in the previous chapter, the most common response to distress is to seek out people we like and trust to help us and give us the courage to go on. We may also calm down by engaging in a physical activity like biking or going to the gym. We start learning these ways of regulating our feelings from the first moment someone feeds us when we’re hungry, covers us when we’re cold, or rocks us when we’re hurt or scared.
