Intergenerational Trauma
The transmission of unresolved trauma from one generation to the next through psychological, behavioral, and epigenetic pathways — so that the unprocessed wounds of parents and ancestors shape the nervous systems, beliefs, and relational patterns of their descendants.
Intergenerational trauma — also called transgenerational or multigenerational trauma — refers to the way that unresolved traumatic experience is transmitted across generations, shaping the psychology, nervous systems, and relational patterns of descendants who did not directly experience the original wounding.
The mechanisms of transmission are multiple: behavioral (traumatized parents parent in ways that re-traumatize children), psychological (unprocessed grief, shame, and fear are communicated through family narrative and relational dynamics), and epigenetic (emerging research suggests that traumatic experience can alter gene expression in ways that are heritable).
How It Transmits
Intergenerational trauma transmits most directly through parenting: a parent who has not processed their own trauma will have a dysregulated nervous system, limited affect regulation capacity, and unconscious behavioral patterns that create an environment for the child similar to the one that wounded the parent. The parent is not usually aware they are doing this.
It also transmits through silence: the things that cannot be spoken in a family system carry enormous weight. Children are exquisitely attuned to the emotional atmosphere and will often carry, in their own bodies, the grief or fear that their parents were unable to hold consciously.
Historical and collective trauma — war, displacement, famine, systemic oppression — transmits through all these pathways simultaneously, across communities and cultures.
How It Shows Up
Intergenerational trauma shows up as fears, shame responses, and relational patterns that seem disproportionate to one's own life experience. As anxiety that cannot be traced to a personal history. As the sense of carrying a heaviness that doesn't fully belong to you.
How It Heals
Healing intergenerational trauma requires both personal therapeutic work — metabolizing what one's body carries — and the larger work of naming the inherited patterns, grieving what was passed down, and consciously choosing not to pass it further.
