Toxic stress weakens the architecture of the developing brain, which can lead to lifelong problems in learning, behavior, and physical and mental health. When a child experiences toxic stress, the Hypothalamic Pituitary and Adrenal (HPA) hormone axis is over-activated.
Does stress affect brain development?
Neuroscientists are discovering that early childhood stress can affect brain development. High levels of stress, especially in early childhood, affect the development of the prefrontal cortex. So cognitively, the brain’s executive functions like working memory and self-regulation may not be fully developed.
How are children affected by stress?
The incidence of obesity, diabetes and heart problems, cancer and other diseases goes up when a child lives with toxic stress. Additionally, their chances of depression, substance abuse and dependence, smoking, teen pregnancy and/or sexually transmitted disease, suicide and domestic violence greatly increase.
Are there things that can hinder a child’s brain development?
Research shows that when children are exposed to negative experiences like neglect, mental illness in the household, trauma or abuse at a young age, the brain’s ability to build circuits that allow different regions of the brain to communicate and process information can be impeded.
Can stress stunt a child’s growth?
“Youngsters who live in very stressful situations have been found to have less growth hormone. If they are taken out of that unhappy situation, the hormone levels recover. Such young people do not necessarily turn into short adults – they just grow more slowly.
How stress affects the teenage brain?
Adolescent brains may be more sensitive to the stress hormone cortisol and may feel its effects more quickly. The part of the brain that is responsible for shutting down the stress response, called the prefrontal cortex, is less developed in adolescents, so stress may also be experienced for longer periods.
What is toxic stress in a child?
Toxic stress response can occur when a child experiences strong, frequent, and/or prolonged adversity—such as physical or emotional abuse, chronic neglect, caregiver substance abuse or mental illness, exposure to violence, and/or the accumulated burdens of family economic hardship—without adequate adult support.
What positive effects can stress have on children’s development?
Stress clearly has an impact on one’s mental well-being with more and more research suggesting “…that children who are mentally healthy are better able to meet life’s challenges. They are also better learners and have stronger relationships” (Kids Matters Webinar, 6 April 2016).
What are 3 factors that influence brain development?
How well a brain develops depends on many factors in addition to genes, such as:
- Proper nutrition starting in pregnancy.
- Exposure to toxins or infections.
- The child’s experiences with other people and the world.
What are 4 signs of stress or distress in toddlers?

- Focus on the positives.
- Schedule relaxing activities.
- Model approach behavior, self-care, and positive thinking.
- Reward your child’s brave behaviors.
- Encourage good sleep hygiene.
Which area of the brain is highly affected by stress?
Chronic stress has a shrinking effect on the prefrontal cortex, the area of the brain responsible for memory and learning. While stress can shrink the prefrontal cortex, it can increase the size of the amygdala, which can make the brain more receptive to stress.
How does toxic stress affect learning and behavior?
Toxic stress decreases the size and impairs the functioning of the regions of the brain responsible for learning, memory, executive functioning (prefrontal cortex, hippocampus). As a result, the child is placed at risk for having learning and behavior problems.
Is toxic stress a trauma?
Trauma is the emotional, psychological, and physiological residue left over from heightened levels of toxic stress that accompanies experiences of danger, violence, significant loss, and life-threatening events.
