When Biography Affects Biology: The Lifetime Impact of Childhood Trauma

It has been called “the greatest public health issue of our times,” a condition that a strong body of scientific research shows can make people two times more likely to smoke, seven times more likely to struggle with alcoholism, 10 times more likely to use drugs, and 12 times more likely to attempt suicide. Children with this condition are 32 times more likely to exhibit behavioral problems in school. As adults, they are twice as likely to be diagnosed with cancer and four times more likely to have emphysema as well as other medical issues. The condition? Significant childhood adversity.

This information was new to me, even having been a practicing social worker for more than 10 years. (Current social work students are taught about this research.) It was less surprising to Chana, a wonderful wife and mother, who shared with me that she had experienced at least four adverse experiences as a child, including having a parent with an addiction and mental health issues and another parent who was verbally abusive. She also remembers experiencing significant stress and anxiety as a child when witnessing her parent hurting some of her siblings in an out-of-control rage.

Chana definitely feels that the cumulative effect of these experiences contributed to a number of physical and mental health challenges that she experienced as a young adult. “Baruch Hashem, I am in a completely different place now, but when I was eighteen, I struggled with severe anxiety, rapidly cycling moods (with extreme highs and lows), self-harm, and suicidal ideation among other issues. Because my inner world was so crazy and painful, I was attracted to unhealthy relationships that made things even worse for me.”

In addition to her mental challenges, Chana struggled with a number of medical issues including a hormone imbalance that sometimes got so bad that she would get migraines, vomiting, and severe cramping. “I also had a pain that is hard to explain,” continues Chana. “It was a hot crawling sensation so intense that made me want to rip my skin off.”

Shira is another survivor of childhood adversity. Her childhood was less dramatic than Chana’s but traumatic nevertheless. “I grew up in a very stressful and chaotic home. When I was at home, I always felt stressed out and anxious. I did not feel like I could speak to my parents about my feelings – or like they cared about my inner world.” Today, as a mother to five challenging children, Shira experiences a lot of stress in her life and has had a number of medical issues that she feels may be related to her early childhood experiences, including frequent headaches and irritable bowel syndrome. She has also struggled with anxiety and depression throughout her adulthood.

The groundbreaking study that clarified Chana’s and Shira’s conditions was done by Kaiser Permanente and the CDC in 1997. A group of 17,000 individuals was asked about 10 specific types of adverse childhood experiences (called ACEs). They included various types of abuse and neglect, exposure to domestic violence, household substance abuse, household mental illness, parental separation or divorce, or an incarcerated household member.

Two thirds of the subjects reported experiencing at least one adverse childhood experience and 40 percent had experienced two or more. The number of ACEs experienced correlated with increased health, social, emotional, and behavioral challenges as people aged. More surprisingly, ACE scores also correlated with many health issues, including depression, heart disease, cancer, and chronic lung disease. Those with especially high ACE scores lived, on average, 20 years less than their peers.

This groundbreaking study demonstrated a clear connection between early childhood experiences and later life behavioral, emotional and medical issues. These challenges persist even as people age, with new research showing an increase in dementia rates among those who experienced significant adversity as children.

Shira’s experience with physical illness can be understood in light of new ACE research. At the time of the original ACE study, it was unclear how childhood trauma could impact a person’s body and brain in such a long-lasting way. Since then, many biological mechanisms have been identified and studied. In particular, it is now understood that significant adversity or trauma causes the brain to be thrust into “fight or flight” mode. According to Donna Jackson Nakazawa, an author of a number of books related to ACEs and health, this state of hyper-arousal can become chronic – which means that the person is being exposed to numerous stress hormones and inflammatory chemicals on a daily basis. This is especially destructive for children, whose brains and bodies are still developing. Nakazawa explains that this causes long-term physiological damage and chronic inflammatory health problems such as high blood pressure, diabetes, strokes, autoimmune disease, asthma, bowel issues and even heart disease.

Of course, early adversity is very common and usually not apparent to outsiders. Unlike parental divorce or incarceration, ACEs like emotional abuse or other serious stressors that lead to a state of chronic stress are more subtle and easier to cover up but are just as harmful to development. Thankfully, some environmental factors, such as having a supportive caring adult involved in the child’s life, can buffer the effect of ACEs on a person’s life.

Neither Chana nor Shira initially identified their early trauma as the factor contributing to their challenges as adults but found healing when they eventually made the connection.

Over the years, Chana has found multiple interventions that have helped her. She participated in both individual and group therapy. The therapy that was most helpful for her, however, was the one that addressed her trauma directly and taught her to treat herself (and her “inner child”) with kindness. On a practical level, she found Dialectical Behavioral Therapy (DBT) – which includes tools for better coping, mindfulness, and communication – to be “life-changing” and extremely useful in her healing process. Chana shared, “In addition to therapy, improving my nutrition and incorporating yoga into my life has really helped my healing. I also feel grateful to have started a support group for women who have experienced similar issues and it gives me a lot of satisfaction.”

Shira also found therapy helpful. “Before seeing a therapist, I saw many medical professionals regarding my irritable bowel symptoms, but had minimal relief from the interventions I tried,” Shira said. “After starting therapy and addressing some of the experiences I had been through, my IBS has almost completely gone away and my mood has improved significantly. It also helped me understand some of the roots of the stress I experience when dealing with my children.”

Donna Jackson Nakazawa’s books are full of hope for those who have experienced early adversity. In Childhood Disrupted: How Your Biography Becomes Your Biology, and How You Can Heal, she writes, “No matter how old you are, or how old your child may be, there are scientifically supported and relatively simple steps that you can take to reboot the brain, create new pathways that promote healing, and come back to who it is you were meant to be.”

Chana says, “When I finally surrendered and handed my heart, brain, and hormones to Hashem, it was life-changing. Things calmed down a lot after that. I am doing so much better now, and I try to keep my life light, positive and simple. I also found that being in a healthy marriage with someone who is safe and feeling true love and belonging is healing beyond words.”

Like Chana, many others have found that healthy, supportive relationships and connecting to spirituality have helped them navigate the inevitable challenges that occur in their lives. And many individuals who have worked through the significant adversities they have experienced, emerge with a deeper perspective on their own challenges and those of others, and lead very successful, fulfilling lives.

Chana reflects, “I really feel that I have gifts that came from my experiences. While I would never want to go back there, I have gained invaluable life skills, perspective, and emunah that give me solid strength and joy on a daily basis.” As Nakazawa writes, “Ultimately,…you don’t just become who you might have been if you hadn’t so much childhood suffering…. You gain something better: the hard-earned gift of life wisdom, which you bring forward into every arena of your life.”

“Post-traumatic growth,” a concept from positive psychology, may explain this phenomenon. PTG suggests that, for some people, adversity or trauma can lead to a level of functioning that is even higher than their level of functioning was prior to the traumatic event. Tedeschi and Calhoun, researchers who first described this construct in the mid-1990s, explained that, “[PTG] is manifested in a variety of ways, including an increased appreciation for life in general, more meaningful interpersonal relationships, an increased sense of personal strength, changed priorities, and a richer existential and spiritual life.”

As Shira points out, “I really feel that my experiences, while very difficult and stressful, have helped me become a deeper and more sensitive person. I am able to relate better to those who are struggling around me and be a better wife and mother to a large family. I’m not sure I would ask for the challenges I had, but I definitely can see how they have helped me grow as a person.”

The ACE study demonstrated the need for us to take childhood trauma seriously and by doing so find ways to manage its impact on our health and mental health as a society. Thankfully, many solutions and interventions are being studied and recommended at this time, and there are multiple paths to healing and gaining the tools to help us lead long, healthy lives. Next month, in part two of this article, I will discuss these interventions in detail.
