You're not imagining it. A growing body of research suggests some emotional pain travels through families, passed down from ancestors who never got the chance to heal it themselves. Scientists call this intergenerational or ancestral trauma, and it's gaining traction in both clinical research and holistic healing spaces.
This article breaks down what ancestral trauma actually is, how to recognize it, what the science says about genetic transmission, and the paths people are using to heal it, including Family Constellation work.
Key Takeaways
- Ancestral trauma is emotional pain inherited from previous generations through biology, behavior, and family dynamics
- Signs include unexplained anxiety, repeated relationship patterns, and a sense of "carrying" something that isn't yours
- Healing combines awareness, professional support, and nervous system regulation, not willpower alone
- Family Constellation work addresses the whole family system, often producing shifts in a single session
What Is Ancestral Trauma?
Ancestral trauma (also called intergenerational or transgenerational trauma) describes trauma passed from a survivor to their children and grandchildren. It's not a formal clinical diagnosis. It's a recognized pattern that researchers and therapists are still working to fully map out.
Two pathways carry it forward:
- Epigenetic transmission — biological changes affecting how genes express themselves
- Cultural and behavioral transmission — learned coping patterns, family silence, and stories passed down (or deliberately not told)
Leah and Bruce Kalish, who facilitate Family Constellation work in Los Angeles, describe it this way: people often repeat feelings and dynamics that aren't theirs but are rooted in tragedies from their family's past.
What the Research Shows
A 2014 study of First Nations adults found that psychological distress increased with the number of generations affected by Indian Residential Schools, even after controlling for age, gender, and income (Bombay et al., 2014).
A broader 2025 systematic review of 18 studies spanning genocide, war, and displacement found consistent evidence of biological and psychological effects on descendants. The authors cautioned that small sample sizes and self-report data still limit firm conclusions.
Common historical sources include war, genocide, slavery, forced migration, colonization, and displacement. What separates ancestral trauma from personal trauma like PTSD is simple: the descendant carries symptoms without having lived through the triggering event themselves.
How Do You Know If You Have Ancestral Trauma?
Ancestral trauma doesn't come with a diagnostic checklist. Instead, it shows up as patterns that feel disconnected from your own lived experience.
Watch for these indicators:
- Recurring fears you can't trace to a personal event
- Family patterns of addiction, estrangement, or silence around certain topics
- A sense of being "responsible" for pain that predates you
- Feeling stuck in cycles that seem to repeat across generations
What Are the Signs of Emotional Trauma in Adults?
Adults carrying inherited trauma often report symptoms that overlap with standard trauma responses, but without a clear personal cause:
- Chronic anxiety or hypervigilance
- Emotional numbness or difficulty trusting others
- Sleep disturbances
- Unexplained physical symptoms (headaches, tension, chronic pain)
These signs can differ from classic PTSD because there's no direct memory attached. One LCSW who worked with Leah and Bruce Kalish described learning to recognize when past trauma was quietly driving her thoughts and behaviors.
Adoptees and people with unclear family histories often notice these patterns most acutely. Karen, a client of the Kalishes, said a single Family Constellation session changed how she felt about being adopted and finally named feelings she had carried for years.
Can Ancestral Trauma Be Passed Down Genetically?
Not through changes to the DNA sequence itself. The science that matters here is epigenetics: shifts in gene expression—the settings that turn genes up or down—without rewriting the underlying code. Think of DNA as the hardware and epigenetic markers as software settings that can switch on or off.
The most-cited study here comes from Rachel Yehuda's team, who examined Holocaust survivors and their adult offspring. They found altered methylation at the FKBP5 gene, a site tied to stress regulation, in both survivors and their children compared to controls (Yehuda et al., 2016).
What this means in practice:
- These markers may influence risk for anxiety, depression, and PTSD in later generations
- What may carry forward is an expression pattern, not a rewritten genetic code
- Epigenetic marks are not necessarily permanent
That last point matters. Epigenetic changes involve "writer" and "eraser" enzymes that can, in principle, shift patterns over time.
Researchers stress this is not proof that any single intervention reverses inherited trauma. It does suggest healing work may hold biological relevance alongside its emotional impact.
How Ancestral Trauma Affects Mental Health, Relationships, and Identity
Inherited trauma doesn't stay contained. It ripples across three areas of life.
Mental health. Research on Holocaust survivor offspring found notably higher rates of generalized anxiety disorder (18.4% vs. 3.1% in the general population) and major depressive episodes (13.7% vs. 6.7%), based on a study of 190 adult children (VA Research, 2016).
Substance use often follows the same pattern, as people reach for ways to quiet inherited anxiety and low mood.
Relationships. Descendants of trauma survivors frequently show:
- Insecure or anxious attachment styles
- Persistent trust issues with partners and family
- Repeating parental dynamics they never consciously chose
Couples work with the Kalishes often surfaces impasses that trace back to unconscious systemic entanglements—two partners acting out roles inherited from their family systems.
Identity. Some people feel disconnected from their heritage or carry guilt and shame that doesn't match anything in their own history. In individual and couples sessions, the Kalishes return to a clear reframe: family events happened before the client, not because of them.
Adoptees report this identity confusion with particular intensity. They're often navigating two family systems at once, which is why clinicians who specialize in inherited trauma treat adoption-related wounds as a distinct focus.
How Can Ancestral Trauma Be Healed?
Healing ancestral trauma takes more than insight. It calls for awareness, professional support, and steady work with the nervous system. Foundational first steps:
- Learn your family history, including the parts that were kept quiet
- Acknowledge the emotions tied to those events, even secondhand
- Seek trauma-informed therapy to process patterns safely
Family Constellation Work
Family Constellation therapy, developed by Bert Hellinger in the 1980s, treats the entire family system as the client—not only the person in the room. A 2021 systematic review of 12 studies (568 participants) found a statistically significant improvement in mental health outcomes after the intervention, with a moderate effect size (Hedges' g = 0.531). Leah and Bruce Kalish facilitate this work in Los Angeles and via Zoom. Mark Wolynn, founder of the Family Constellation Institute, has called them "masterful facilitators, bringing warmth, depth, wisdom and compassion to those whose hearts they touch." Their sessions focus on:
- Nervous system regulation and easing chronic stress patterns
- Adoption-related identity and family healing
- Release of long-held ancestral wounds, sometimes with marked shifts in a single session One client, psychotherapist Hala Khouri, described their sessions as a "solid container" where inherited trauma patterns can surface and shift. Complementary practices worth adding:
- Rituals that honor ancestors
- Storytelling that gives voice to unspoken family history
- Forgiveness work that releases what no longer needs carrying—without excusing harm
How Can Adults Heal From Childhood Trauma?
Personal and ancestral healing aren't separate tracks. They intersect constantly.
Working through your own unresolved trauma often surfaces deeper ancestral patterns underneath it. Research on refugee families found that parent-child attachment and communication quality were key pathways for transmitting (or interrupting) trauma across generations (Sangalang & Vang, 2017).
Healing your own patterns is one of the more concrete ways to keep from passing the cycle forward.
The most complete approach usually combines:
- Individual therapy for personal trauma processing
- Family-systems work like Family Constellations for inherited dynamics
- Somatic or nervous-system-based practices so the body, not just the mind, can release what it has held
Leah Kalish describes her own healing as requiring both modalities: Family Constellation work to address inherited imprints, and Embodiment Process sessions to address developmental and accident-related trauma stored in the body.
Frequently Asked Questions
How do you know if you have ancestral trauma?
Look for recurring emotional patterns, unexplained fears, or family history clues like addiction or estrangement that repeat across generations. Symptoms often appear without a personal traumatic event to explain them.
What are the signs of emotional trauma in adults?
Common signs include chronic anxiety, hypervigilance, emotional numbness, difficulty trusting others, and relationship struggles. These can occur even without a direct memory of a triggering event.
Can ancestral trauma be passed down genetically or change DNA?
Epigenetics changes how genes express themselves, not the DNA sequence itself. Studies on Holocaust survivors' offspring found altered stress-related gene markers, though this isn't the same as inherited DNA mutation.
How can ancestral trauma be healed?
Healing typically requires awareness of family history, professional support, and nervous-system-based work. Family Constellation work and trauma-informed therapy are two approaches often used to address these patterns.
How can adults heal from childhood trauma?
Combining individual therapy with family-systems approaches, like Family Constellations, helps process personal trauma while addressing inherited patterns. Working with a facilitator trained in both helps you release what is yours and stop carrying what never was.
