Research from 2019Trusted Source found that stress during pregnancy is one way intergenerational trauma can be passed down. Parental stress during pregnancy is associated with children who have:
autism spectrum disorders
schizophrenia
attention deficit hyperactivity disorder (ADHD)
Researchers first discoveredTrusted Source the generational impact of trauma on the children of people who lived through the Dutch famine (the “Hunger Winter”) during World War II.
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.
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.
Scientists also found that trauma can have a generational impact when they studied the children of Holocaust survivors, as one 2015 study found.
A 2018 reviewTrusted Source suggests a link between intergenerational trauma and depression, too. They found evidence that trauma can be passed between generations epigenetically, which means that trauma experienced by an ancestor might affect the way your genes are expressed.
I took this information from the following article which contains really interesting information about this question:
