Parental advisory: Maternal and paternal stress can impact offspring neurodevelopment. Some might find it helpful to consider the scientific basis for post-traumatic growth and resilience as they sort out how previous generations have impacted them. No one can be expected to demonstrate growth or recovery before they are ready, especially in the face of trauma spurred on by systemic racism or socioeconomic status. Know resilience and post-traumatic growth are possibleįacing any form of trauma is incredibly hard, and perhaps especially so when the trauma derives from your family of origin. There’s a good chance these efforts might impact your future children. Try to expose and immerse yourself in positive surroundings and healthy relationships where your needs can be met. The study, published in Nature, found that the offspring of mice are impacted by both positive and negative experiences of their parents. Research from 2016 found that enriching our environments may impact us and future generations. Thanks to neuroplasticity, our brain can change. Studying that list may lead to psychological insight.īoth positive and negative environments impact our brain. Make a list of the personal history your ancestors endured and perhaps discuss it with living family members if there is mutual openness and safety.Consider the cultural and religious values of certain eras that may have influenced your family’s belief system.List the wars, political movements, and other major historical events that your ancestors lived through and consider the ways those events shaped your family.Here are some research ideas to get you started: Discover your family historyĮven if you don’t know about the trauma history of your lineage, learning about your family history might help you consider how what your family went through in their lifetimes may or may not have affected you. While more research is needed, below are some paths toward healing to consider. A lot of work still to be done here,” Bale says. “Healing trauma is so important, but not easy to do, and certainly something we don’t understand at the biological level. When researchers from Columbia University studied the death records of children of the Dutch famine for a 2013 study, they found that prenatal famine was linked to lower mortality. Several studies conducted in the 1970s found that the children of pregnant women during this famine were more prone to higher-than-average body mass and diabetes, thus forming the basis for future research on intergenerational, or transgenerational, trauma. Researchers first discovered the generational impact of trauma on the children of people who lived through the Dutch famine (the “Hunger Winter”) during World War II. ![]() dysfunctional dynamics between you and your family members that result from trauma, such as codependency, unhealthy attachment styles, or parental dissociation.Some nonbiological ways trauma can be passed down between generations include: attention deficit hyperactivity disorder (ADHD).Parental stress during pregnancy is associated with children who have: Research from 2019 found that stress during pregnancy is one way intergenerational trauma can be passed down. Here are some ways trauma can impact generations: While experts are still researching the biological factors of inherited trauma, research does offer us a view into how trauma from generations past can impact future generations. ![]() This suggests that some aspects of trauma may be inherited.Ī study from 2018 explored the notion that trauma may be passed down through epigenetic mechanisms, possibly impacting DNA and gene function, but it concluded that more research is needed. What’s less understood or talked about is how it impacts the next generation.Īlthough post-traumatic stress disorder (PTSD) is usually linked with personally experiencing trauma, some twin studies have estimated that the heritability of PTSD is between 30% and 70%. It’s no secret that trauma can change us.
