Toxic Stress Caused by Adverse Childhood Experiences (ACES)
HOW DEVELOPMENT IS DISRUPTED
Learning how to cope with difficulty is an important part of healthy development. When we experience stress or adversity, our brain’s stress response system is activated and goes on alert. When the stress is relieved, the stress response system winds down and the body returns to normal.
For young children, this return to normal depends upon the presence of supportive adult caregivers who can help relieve the stress a child experiences—whether the stress is normal and essential (positive), more severe and longer-lasting (tolerable) or strong, frequent and prolonged (toxic).
When caring adults are not present, stressful situations such as exposure to violence or neglect cause a child’s stress response system to stay activated. Constant activation of the stress response overloads developing systems in the brain, leading to serious lifelong consequences. When the stress response system is set on high alert for prolonged periods, scientists call this toxic stress.
Toxic stress can reduce important neural connections in areas of the brain, just when those connections should be growing. The release of stress hormones causes neurons to die off instead of making vital connections. To prevent toxic stress from harming children, the Council promotes environments that are nurturing, interactive and stable.
ADVERSE CHILDHOOD EXPERIENCES
The incidence and effects of childhood trauma—also called Adverse Childhood Experience (ACE)—was the subject of a large-scale study from 1995-1997. In this study, 17,000 members of the Kaiser Permanente Health Plan (average age 57) were asked to complete a confidential survey that contained questions about childhood maltreatment and family dysfunction, as well as their current health status and behaviors. The study was a collaboration between the federal Centers for Disease Control and Prevention and Kaiser Permanente. It was perhaps the largest scientific research study of its kind, analyzing the relationship between multiple categories of childhood trauma and health and behavioral outcomes later in life. Co-principal investigators were Robert F. Anda, MD, MS, and Vincent J. Felitti, MD. Dr. Felitti has become a friend to Maine and has helped guide the Council’s work.
