TRAUMA DAMAGE TO NEURODEVELOPMENT
Life and Death: An Example
Tracyās eyes sparkled and locked onto my own from the moment I met her. I was struck by her chunky cheeks, carefully braided hair, and cute button nose. Tracy smiled up at me as though she had known me for forever.
āThis is Tracy,ā her county social worker announced. Four-and-a-half-year-old Tracy reached out her hand and gently placed it into mine. Then, without a look behind at her social worker, Tracy began walking with me past doors, up stairs, through halls to my office, her steps confident and secure, her chin tilted upward, and her golden brown eyes gazing upward at me. I thought of Little Orphan Annie.
Tracy lived with her mother for her first eighteen months and then lived for two years with a friend of her motherās who brought her to child protective services, saying she could no longer care for her. Tracy was placed with a foster family where she had been living for almost a year. I asked Tracy to draw pictures of her foster mother, her biological mother, and her motherās friend. She smiled up at me and began to draw primitive sketches, even for her age, huge heads for each figure taking up half a page each, an imaginary line separating each of her mothers.
Each figure had immense, bulging oval eyes. On the picture of her mother, Tracy sketched a jagged slash through her motherās eye, her memory. (I later learned that Tracyās mother had cut her in the face with a knife.) Her motherās friend was drawn with similar jagged scars on the sides of her face.
After sketching her three mothers, I asked Tracy to include herself. She drew a smaller oval head than she had drawn for her mothers, but she included the same bulging eyes. Tracy added two short lines for legs, just as she had in the other pictures. Then, Tracyās face tensed and she pursed her lips. She bore down on her black marker and began scribbling from left to right, zigzag slashes, repeated over and over until she had totally obliterated her drawing.
āMe.ā Tracy said simply. She smiled, gazing up again into my eyes.
Tracy was going to be evicted from her foster family. Her foster mother was a manager with a demanding schedule and had bravely offered to care for schoolage children who could not live in their own families. The county case worker had begged her to take Tracy on a temporary, emergency basis. Weeks stretched into months, and Tracy was no closer to having a secure or lasting home. A year went by. Tracyās foster mother said she could not keep Tracy any longer. She had worked out a way to provide day care but she could no longer manage what caring for Tracy had done to her own life. Tracy screamed every night, a piercing howl that fractured her foster motherās sleep. She was exhausted.
Tracy showed me how the loss of a parent is similar to the obliteration of a childās identity and his or her very being. Despite losing three mothers, Tracy had not given up. She held my hand and gazed at me with an appealing smile. She was still looking for someone to love her.
I have seen hundreds of girls and boys such as Tracyāinfants, toddlers, young children, adolescents, and young adults who continue to search. Although they have learned that they cannot trust, deep down they keep wishing for someone to love them.
ATTACHMENT THEORY AND RESEARCH
Shaping a Life
Dependence on an parent is a fact of life for all children, and in fact, all primates. Humans, by nature, have the longest period of dependence of any animal and simply do not survive without the twenty-four-hour-a-day care and support of their parents. Attachment to a caring parent means survival. Abandonment to a young child means death.
Bonding begins before conception. The security of a childās future life begins with the resources a mother and father bring with them. The parentsā relationships, wealth, heritage, and community can support or constrain their union and their ability to support their child. Was this conception sanctioned or unsanctioned? Will the newborn be accepted and cared for, neglected, or rejected by parents, grandparents, extended family, neighbors, educators, and community leaders? What does the fetus represent, not only to the mother and father, but to the extended families now united through the growing embryo who forms the future of both families? Are the parents living in a neighborhood with playgrounds, enriched schools, and after-school activities or an impoverished battleground dominated by rival gangs and drug dealers. The answers form the emotional and social cradle that nourishes or impedes an infantās growth.
The brain has developed, according to neurological researchers (Schore, 1994, 2003a; Siegel, 1999, 2003), in sequence from more primitive functions such as the brain stem, which manages basic autonomic functions, to the limbic system, with the hippocampus mediating memory and learning, the amygdala processing emotional memories, and the anterior cingulate working rather like a coordinator of bodily responses to higher-level thinking. The prefrontal cortex provides verbal (left hemisphere) and visual, tonal, and emotional reasoning (right hemisphere), and the cortex serves many distinct functions necessary for visual, auditory, and affective processing. Some connections in the brain are classified as life critical and develop with little adaptation in order to manage basic life functioning such as the infantās heart rate and breathing. Higher-level connections have been found to be shaped by experiences (Siegel, 1999; Schore, 1994; Perry, 2001). Brain growth builds from conception with each stage of growth forming the foundation for higher levels of functioning.
Neurobiologists have discovered how the infantās brain is altered by chemicals experienced in utero. Prenatally stressed infants may have difficult temperaments resulting from environmental stress, poor nutrition, and toxic chemicals on their developing nervous systems. A pregnant woman stressed from traumas produces increased hormones, such as cortisol. These hormones strengthen her body in the short term but increase the likelihood of blocking development of connections in the fetusās developing brain or decreasing the number of brain cells. Parts of the brain needed for memory and learning (e.g., the hippocampus) may be impaired. Studies have shown how cortisol decreases memory ability and the ability to sustain attention.
Similarly, norepinephrine, a critical hormone for self-protection, can have an adverse effect on infants and fetuses. Norepinephrine brings a human to the āfight-or-flightā level needed for survival. Too much, however, can lead to panic. If the infant is exposed to high levels of norepinephrine, the level of agitation can become a persistent state in which he or she is always on guard looking for threats and expecting harm. High levels of norepinephrine increase excitable neurons. The infantās system essentially becomes sensitized and even normal stressors can ignite the preprogrammed stress response generated by the development in utero or early infancy with too much norepinephrine. This has been called kindling, a level of neuronal excitability caused by repeated stress.
After birth, brain development continues to be shaped by environmental factors that stimulate the organization of neural interconnections (Kotulak, 1996; Shore, 1997; Siegel, 1999). Researchers have classified some neural connections as experience-expectant and thus greatly impacted by culture, heritage, nurture, and the experiences of a child. Experiences of the fetus and young child have a major impact on the cultivation and pruning of neural synapses, and key experiences have been found to be necessary within extended time periods, sometimes called windows of opportunity, for optimal development of different brain centers.
Stress on a parent and child accordingly impacts the infantās developing brain in different ways at different stages of development. The absence of stimulation through profound neglect, such as a baby being left in its crib, or over stimulation from trauma (e.g., abuse or violence) can result in the failure of the infant to complete certain tasks and distort development of neuronal functions. This is one of the reasons why siblings who experience violence, sickness, or loss at different ages respond to the same trauma in different ways. Parents may misunderstand how one child, who was one year old at the time of violence in the family, became hyperactive and was later expelled from kindergarten for aggressive behavior, while an older child, who was eight years old at the time of the violence, was able to continue to succeed at school, even though the child became preoccupied with the care and protection of a parent at home.
Overemphasis on the impact of damage during prenatal experiences can also lead policymakers and funding bodies to give up on children seen as irreparably damaged in utero. In the late 1980s, it was feared that babies born to crack-addicted mothers would be maimed for life. Instead, it has been learned that the familyās environment after birth may have a stronger effect on a childās temperament than the experience of cocaine in utero. Schore (2001) found that as many synapses develop in the nine months after birth as in the nine months in utero. Accordingly, the level of stress experienced growing up with a mother who was or had been crack-addicted, may have a stronger impact on a childās brain than the infantās experience of cocaine in utero. Well after an infantās diagnosis as having fetal cocaine or fetal alcohol effects, parenting, educational, and therapeutic interventions make a tremendous difference in his or her life.
A childās early years have now been well publicized as critical. The public, however, has been less informed about how a childās environment continues to shape brain development well through adolescence (Thompson and Nelson, 2001) and into young adulthood. Brain centers most relevant for cognition and higher-order thinking operations such as problem solving, reasoning, self-regulation, and strategic thinking develop well into adolescence. Moreover, the adult brain also has been found to reorganize based on life experiences (Greenough and Black, 1992; Elbert et al., 1995; Ramachandran, 1995) with growth of new neurons occurring through-out the life span (Eriksson et al., 1998; Gould, 1999). Although brain growth is especially vulnerable during the prenatal period and a childās early years, the lifelong process of brain development presents opportunities for remediation.
Windows for Growth
Watching a new parent cradle an infant is a beautiful sight. The infant signals its needs through a whimper or cry. The parent responds with a smile, a caress, a nipple, or a bottle, removing pain and satisfying the needs of the infant. Eye to eye, coo matching coo, the infant feels united with a parent, building a linkage over time and the foundation for trust (Erikson, 1986). Attachment is an interactive process (Schore, 2003a; Siegel, 2003), brain to brain, limbic system to limbic system, a synchronicity of parent and child. Attachment in the childās first three years centers on communication between the right brains of both parent and child, especially visual, face-to-face images of one another, touch, and tone of voice. These experiences form indelible memories in a childās limbic system, long before a child develops the capacity to utilize language, including expectations of whether parents will respond to distress, whether the child will be soothed, and whether parents can modulate their own emotions at times of stress.
In the first stages of development, the infantās needs must come first, but the infant-parent dyad is controlled by the nurturing parent, typically the mother. This is the stage of development where the brain stem and thalamus are being shaped. The infant absorbs the care from the parent and essentially absorbs the self-regulatory system of the parent. When the infant is cared for fully, the infant grows up feeling wanted. When the infant experiences a lack of response, his or her regulatory system fails and the infant may die.
Infants learn whether they can trust that their needs will be met. They are shaped by the sensitivity and responsiveness of their parents. Those who experience a high level of stress at this point of development will often develop a state of hyperarousal. Infants who experience intermittent care learn that the world is unpredictable and become unpredictable in their own lives. Those who experience angry parents become frightened and easily triggered to rage. Infants who experience parents who are depressed and nonresponsive often tend to withdraw, and show a decrease in positive emotions.
From four to six months, the cerebellum and thalamus develop at a high rate. At this point, the infant needs to send clear signals to affect the necessary relationship with the parent. He or she mirrors the gaze and interactions of the parent, and the parent mimics and mirrors the child. Ideally, the infant experiences an attunement between the parent and his or her own behavior.
This is a wonderful stage in which the infant begins to show delight and positive excitement. On the other hand, the infant who has not received the care and stimulation needed will begin to avoid contact with his or her parent and show subdued or inhibited behavior. The infant who experiences inconsistent care will often act chaotic in his or her own behaviors. The infant who experiences a parent who periodically becomes abusive will often avert his or her gaze from the parent and demonstrate the fear learned from his or her parentās rages.
From six to twelve months, the prefrontal cortex develops at a rapid pace. This is the bridge between the survival functions of the limbic system and the higher-level cognitive functioning of the cortex. The development of regulatory functions is shaped by a childās experiences during these critical months. The process of attachment between infant and parent is especially critical from eight to eighteen months. The child learns whether the parent can be relied upon.
The child learns from the parent how to manage problems and stressors. With each month of development, the child increasingly takes a stronger role in signaling what he or she needs. The parentās response to these signals demonstrates whether the child can count on the world around him or her or must try to take control on his or her own of a world that seems out of control. In reality, no parent provides perfect attunement to a child, just as no parent or child lives in a stress-free world. The infant who experiences a sensitive, predictable, and reliable parent learns that his or her parent will regulate intense emotions.
Social and Emotional Development
Mahler, Pine, and Bergman (1975) and Greenspan and Lieberman (1988) described the developmental process of attachment and its impact on a childās cognitive, social, and emotional development. Schore (1994) denoted the critical impact of a mother and childās relationship on the physical development of the brain building the childās framework for future inter- and intrapersonal development. Schore stressed how attunement between a parent and child facilitated growth of the limbic system during the first year. Caregivers provide experiences that regulate hormones in the child and in turn shape gene transcription (Schore, 1997). Interactional experiences modulate genetic development and shape brain circuitry.
From twelve to twenty-four months, the child exercises a great deal of independent action. The parentās attunement provides the foundations for discipline, social skills, and the development of self-control. Researchers have also described the role of separation and shame in shaping a childās ability to integrate a sense of self that incorporates both good and bad behavior. When a child experiences a parent breaking attunement after misbehavior, he or she becomes anxious. Reprimands and withdrawal of attention induce discomfort in the child, that, in turn, shapes his or her behavior. This is critical in terms of developing inhibitory circuits.
Discipline within a caring, nurturing relationship helps the infant learn self-regulation and self-control. The parent scolds or withdraws affection, and then reattunes. Reattunement affirms the childās security with his or her parent. The child calms and over time learns how to regulate his or her own responses in order to keep the parentās attunement. The parentās reattunement helps a child develop a sense of autonomy within the security of a continuing bond. The child learns right from wrong and how to succeed. As the child develops, this learning progresses into verbal communication and use of words to understand and regulate his or her own behavior. Without reattunement, the child learns to live in an unstable, insecure, and often dangerous world in which his or her relationship to the parent is always at risk.
