Trauma alters gene expression. This can get passed down family lines. It is designed to prepare both individuals and their descendants to deal with a dangerous and chaotic world. Unfortunately when this goes too far and can’t switch back off, it can become a family curse. It can turn into a self fulfilling prophesy leading to continuous cycles of pain and frustration.
This curse comes in the form of altered glucocorticoid- and immune-related gene expression. These can have broad reaching effects on the body. They influence psychological states, ability to focus, and function socially.
Offspring of trauma survivors are more likely to develop PTSD, mood, and anxiety disorders and demonstrate genetic alterations. The expression of these genes can cause wide ranging damage from obesity to insomnia and infertility.
Families may be affected financially as well because having intergenerational trauma may make it harder to focus and plan, all of which have long term financial consequences for families often resulting in intergenerational poverty.
