In recent months, it seems as if the public, and policymakers, have caught on to the science on adverse childhood experiences (ACEs, aka “toxic stress”) in a big way. The list of prestigious organizations and government entities collecting and reporting on ACEs data, providing summaries of the science, and implementing trauma-informed interventions include the World Health Organization, the Centers for Disease Control and Prevention, the Substance Abuse and Mental Health Services Administration, the Office of Juvenile Justice and Delinquency Prevention, the American Academy of Pediatrics, the Robert Wood Johnson Foundation, Harvard University, at least18 states, the city of Philadelphia—and Child Trends.*
Why is this new research about ACEs important?
1. It bridges the divide between the biological and the psychological.
Many of the old (and often stigmatizing) distinctions between “mental” and “physical” health just don’t make sense here. The research on toxic stress, particularly as it affects children, reveals how experience modifies the brain and other body systems (immune response, hormone activity). Chronic early stress alters children’s emotional responses, their impulse control, and their attentional and decision-making processes. It puts them at risk, in adulthood, for cardiovascular disease, obesity, substance abuse, and depression, as well as early death. Thanks to this research, we’re poised to take a more holistic view of wellness.
2. It reinforces the importance of child-caregiver relationships.
The ray of hope in this new knowledge is that a child’s safe, stable, and nurturing relationship with a caregiver plays a buffering role against these toxic effects. Good parenting (or, when that’s lacking, sensitive care from another adult) can protect children from the harms they might otherwise incur from overwhelming stress, or even, in some cases, can help undo the effects of prior trauma. Relationships matter.
3. It recasts much of the old debate about poverty.
Do you explain poverty as mainly the result of a number of unfavorable circumstances beyond one’s control, or do you ascribe it primarily to personal failings of one sort or another? The research on ACEs and the toxic stress they can create doesn’t resolve that debate, but it most certainly offers a different and potentially more productive frame for thinking about poverty. Living in poverty, we know now, frequently causes an accumulation of stress that becomes toxic. As surely as smoking or obesity, chronic poverty damages health—now, and in the future. Moreover, when it also handicaps cognitive and emotional functions, it becomes harder for the poor to escape poverty.
4. It puts a new spotlight on the toll violence takes on our society.
The ACEs research makes it clear that violence—both directly experienced, and witnessed—is both pernicious in its effects, and is a too-common experience of children. Violence is toxic. Children are wired to recoil from it and, when they cannot, they respond in ways that damage their health and blunt their capacities. It is the responsibility of adults to protect children from violence wherever it may occur, starting at home. It’s a need on a par with their needs for adequate food, clothing, shelter, education, and medical care.
Fortunately, as we learn more about toxic stress, research is also progressing about how to mend the damage it wreaks on children. However, that’s not always reversible. The clearest message here is prevention.
