Understanding Intergenerational Trauma: How Trauma Can Be Passed Down Through Generations

Updated: May 27

Trauma is not only something that affects us individually but can ripple through families, communities, and generations. Whether stemming from childhood abuse, neglect, or collective experiences like war or systemic oppression, trauma can leave lasting marks. One aspect of trauma that often goes unaddressed is its transgenerational impact—how trauma can be passed down from one generation to the next, often unconsciously.


At Curious Mind Counseling, we understand the profound impact of intergenerational trauma and how it can manifest in ways we may not immediately recognize. Understanding this concept can be a powerful step toward healing, not just for yourself, but for your family and future generations. In this post, we will explore what intergenerational/transgenerational trauma is, how it works, and how it can be healed.

What is Transgenerational Trauma?

Transgenerational trauma refers to the transmission of trauma from one generation to another. This transmission can occur in a variety of ways, both emotionally and biologically, and can affect individuals, families, and entire communities. Children and grandchildren of trauma survivors may carry the emotional scars of events they never directly experienced, yet these experiences can impact their mental health, attachment styles, and worldview.


One example of this is the effects of childhood abuse. Parents who were abused as children may struggle with parenting, unintentionally passing down cycles of abuse, neglect, or emotional unavailability to their children. Similarly, individuals who have experienced racial or cultural trauma may inadvertently pass down the burden of that trauma to their children through behaviors, attitudes, or emotional responses.


The Mice Study: Trauma Transference in Action

To understand how intergenerational/transgenerational trauma might work biologically, one fascinating study involving mice demonstrated that trauma could affect offspring, even across generations. Researchers from the Emory University School of Medicine conducted a study where they exposed male mice to a traumatic experience: they were exposed to a specific scent (acetophenone) while receiving a mild shock.


The interesting finding came when these male mice went on to father offspring. The mice’s offspring showed heightened stress responses when exposed to the same scent, even though they had never experienced the shock themselves. The shock-paired scent triggered a fear response, demonstrating how trauma could be passed down through sensory cues—without the next generation having experienced the trauma itself.


Even more surprising was that this response was observed in grandchildren of the original male mice. The trauma response seemed to have been genetically transmitted, affecting the offspring’s ability to cope with stress. This groundbreaking research hinted at the biological underpinnings of intergenerational trauma—showing that trauma can potentially alter genetic expression and be passed down.


While this study was conducted in mice, similar theories are being explored in human research, suggesting that trauma can leave biological “marks” on our genes, influencing future generations’ ability to cope with stress, anxiety, and fear.

How Does Intergenerational Trauma Affect Us?

The impact of intergenerational trauma is complex and can affect various aspects of our lives. Here are a few examples of how it might show up:

• Mental Health Struggles: Children of trauma survivors may have higher rates of anxiety, depression, or PTSD, even if they haven’t experienced traumatic events themselves.

• Attachment Issues: Children may struggle with forming secure attachments if their parents were emotionally unavailable, due to their own unresolved trauma.

• Behavioral Patterns: The behavior patterns of trauma survivors, such as avoidance, hypervigilance, or emotional dysregulation, can be passed down and modeled to the next generation.


In addition to these individual and relational impacts, intergenerational trauma can affect communities. For example, the descendants of enslaved individuals or those who experienced genocide may inherit collective trauma that influences their sense of identity, self-worth, and cultural connection.


Healing from Intergenerational Trauma

Healing from intergenerational trauma requires a multi-faceted approach. Here are some ways you can begin the journey:

1. Recognize the Patterns: The first step in healing is recognizing the ways in which you may be carrying the weight of past trauma. Identifying these patterns can be powerful and transformative, allowing you to make conscious choices moving forward.

2. Seek Therapy: Trauma-informed therapy can be a safe space for exploring the ways in which past generations’ experiences may be affecting you. Through therapy, you can work on breaking the cycles of trauma and learn healthier ways of coping and interacting.

3. Practice Self-Compassion: Healing is not linear. Be kind to yourself as you navigate this journey, knowing that it’s okay to experience setbacks. Self-compassion is an essential tool in working through the heavy emotions associated with intergenerational trauma.

4. Build New Relationships: Healthy, secure relationships can help create new patterns of attachment that are healing and positive. Support from a trusted community or loved ones can help replace old, harmful dynamics with healthier ones.

5. Intergenerational Dialogue: Sometimes, healing can also come from having open, honest conversations with family members about the trauma that has been passed down. These conversations can be difficult, but they can also bring greater understanding and the opportunity for collective healing.
