Bruce Perry: Attachment and Developmental Trauma

BrousBlog9a Perry head shotDr. Bruce Perry, MD (left) documents the brain science of how attachment problems can cause developmental trauma to a fetus, infant, or child – just when the brain is developing.

And he’s taking his “attachment first” approach to Washington.  In “Trauma Impacts the Brain: Healing Happens in Relationships,” Perry leads a full-day Pre-conference University on Sunday May 4, to kick off  the National Council for Behavioral Health’s Annual Conference ’14 on May 5-7 (click here for details).

“Experiences profoundly influence the development of young children. Adverse Childhood Experiences (ACEs) shape the brain’s organization, which, in turn, influences the emotional, social, cognitive, and physiological activities,” the conference website notes.

“So often, trauma happens in relationships, but it is also in relationships that healing occurs. Explore the latest research and clinical treatment with trauma researcher, treatment visionary, and bestselling author of The Boy Who Was Raised as a Dog, and Born for Love:  Why Empathy is Essential and Endangered, Dr. Bruce Perry.”

Dr. Perry’s relationship and attachment theory healing model first assesses each child as an individual, using his  Neurosequential Model of Therapeutics (NMT).  He emphasizes that there is no one label for child trauma. Rather, “there are very individualized patterns of exposure to trauma (all with unique timing, nature, and patterns)… So we don’t call ‘it’ anything,” he wrote me recently. “We describe it — and try to ‘illustrate’ each individual’s trajectory separately” with the NMT’s individualized brain mapping technique. [FN1]

Dr. Perry recommends his books above as the best summaries of his work.  His latest research and key slides are online from his National Council webinar last fall, “Helping Children Recover from Trauma,” National Council LIVE, Sept. 5, 2013 (scroll down to Sept. 2013.)  I really recommend this – and it will only be online through August 2014.

Survival Brain Develops First

BrousBlog9c Perry Slide1 Brain 4 PartsDr. Perry says we’ve got to learn about the neuro-biological growth of the brain in order of time sequence from  conception to later development in infancy and childhood.

His “Four Part Brain” slide (above) shows the time sequence from the bottom up: first the brain stem develops (pink); then the diencephalon cerebellum (yellow); they make up our primitive reptilian “survival” brain.  Next develop the emotional limbic brain which only mammals have (green), and finally the thinking brain aka frontal cortex (blue).

The fetus’ “survival brain” develop first, because infants require breathing, heart beat, and other survival functions at birth, Dr. Perry told a March 2013 UCLA conference. The rest of the brain develops largely after birth and as an outgrowth of the brain stem. [FN3]

So injury during brain stem development in the first 45 months harms development of the entire brain, the neurons around the viscera, and most of the body.

Dr. Perry next details three key threats to an infant’s developing brain:  Trauma in utero (intra-uterine insult); post-birth attachment trauma; and other post-natal trauma – all before the thinking brain comes on line around age 3.

A fetus in utero is designed to develop in nurturing oxcytocin and other “reward” chemicals released by a mother supported by her family, all joyous a baby is coming. Intra-uterine insult occurs when the mother instead uses substances, or is under stress so that her stress hormones impact the fetus’ developing brain. This can be visible stress to the mother: domestic abuse, work stress, violence.

A fetus, however, can also be subject to stress chemicals with no visible external stress to the mother, as in mothers who are anxious, themselves victims of attachment disorder, don’t want a baby, etc.  Often these mothers have no steady pattern to their heart rate, and since a baby’s brain grows according to the mother’s heart rate rhythm, the baby’s brain develops dysregulated.

All these “causes a cascade of mental and physical problems in every part of the body and brain,” Perry says. “Every part of the whole brain these neurons enervate will be dysregulated.”

Birth: the Mother of All Stress

Attachment trauma occurs easily because birth is incredibly stressful to a baby: suddenly there’s lack of oxygen, blinding light, shocking cold, terrifying noise, and pain. This floods a baby with stress hormones — which is essential because now it’s not having needs met as in the womb; thus it’s got to protest so someone comes. “If animals in the wild didn’t feel the stress of hunger they’d just lie around and die of starvation,” Perry notes.

Mom Smile Baby If all goes as designed, an attuned mother meets the baby’s needs, feeds it, swaddles it, turns down the lights, so the baby feels safe and is flooded with reward optiates like oxytocin. If animals didn’t feel opiate rewards when they get up and eat just what they need (not dirt, for example), they’d not get up.

Then they wouldn’t survive, so the stress hormones and the reward opiates are linked. “At the relief of hungry-thirsty-cold stress, we feel pleasure,” Dr. Perry says. An attuned mother “has a well-organized neurobiology to create a healthy organized neural network for the infant of attachment and regulation…

“And in the arms of that caregiver, that is that magic moment literally weaving together the neurobiology of all these different systems. The biology of attachment is that a baby learns by thousands of good experiences that this stress is tolerable because it leads to reward, and this pleasurable outcome is cathexsized to a person, Mom… Ultimately just seeing or hearing Mom makes you feel safe and pleasurable. Let a wounded soldier talk to his mom, he’ll need 45% less pain meds.”

Or not.

If mom instead is under too much stress herself to meet needs, has too many children and no support, or herself was raised by a mis-attuned mom, “she doesn’t get reward from responding to her baby’s distress,” Perry continues. “So the pull to respond isn’t there.”

Even if no stress to the mother is visible, “if she merely meets physical needs, without involving her own pleasure systems, then the weaving together of meeting needs and the reward/safety system is weak or absent. So her baby learns that stress can be life-threatening, that stress is terrifying,” Dr. Perry concludes. [FN3 op. cit.]

The “Or Not” baby’s brain learns: “that’s all she wrote.”

It develops in a state of perpetual stress in which the stress chemicals simply do not stop and the reward chemicals never or seldom come. In this state, fight/flight cortisol flood eventually leads to “freeze” dissociation, Judith Herman reported back in 1992. [FN4]

  1. Bruce Perry and Dan Siegel are part of a group of mental health researchers who are moving away from the medical model of mental health theory and practice. They even mention discarding diagnosis and the DSM in their non-diagnostic, non-medical approach to mental health in their workshops. They, along with Allen Schore and others who use an attachment model for both identify and treating developmental trauma, focus primarily on using a relational model of treatment. Their message about how to heal developmental trauma sounds something like this:
    Presence, attunement and resonance is the way to clinically create the essential condition of trust. This allows clients to experience healing love without fear, as they come to the neuroceptive evaluation of safety. This helps them create trust within their subjective experience.
    This group has bypassed much of the controversy generated by more traditional mental health practitioners. Instead, they’ve moved the focus of their research into validating a relational model of mental health based on the principles of interpersonal neurobiology.
    Dan Siegel and Allen Schore, who oversee a series of textbooks on Interpersonal Biology at W. W. Norton, are at the cutting edge of this.
