What if the struggles you face today began long before you were born?
Most families believe a comforting myth: What happened in the past stays in the past.
Mental illness was thought to die with the person.
Family secrets were believed to be buried in the grave.
Shame was something you simply never talk about again.
As long as the family doesn’t know, the next generation will be safe. But science — and systemic family work — suggest something very different. From a Family Constellation and systemic perspective, what is hidden rarely disappears. It moves through the family system. And this is not just philosophy or theory.
Research in psychology, neuroscience, and epigenetics shows that trauma can influence future generations biologically and psychologically.
Studies of descendants of Holocaust survivors found that trauma exposure in parents can produce epigenetic changes affecting stress-response genes in their children, even when those children never experienced the trauma themselves.
Scientists have found that severe stress can alter how certain genes related to stress hormones are expressed — changes that may be passed to the next generation through biological mechanisms such as epigenetic regulation.
In other words, PTSD does not always stop with the soldier who went to war. It can echo through the nervous systems of their children and grandchildren.
Research across populations — including Holocaust survivors, genocide survivors, and war-affected families — shows that descendants may have heightened vulnerability to stress, anxiety, or trauma-related symptoms.
This doesn’t mean trauma is destiny. But it means something important: Silence does not erase what happened. Unspoken grief, hidden shame, and family secrets often continue to shape the emotional lives of future generations.
At Family Constellation Lab, we explore these hidden family patterns that influence present-day mental health. Not to blame previous generations. But to understand a deeper truth:
What one generation refuses to face, the next generation often feels. And when someone finally acknowledges what was hidden, the cycle of inherited trauma can begin to change.
