![]() 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.

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.
