What is Intergenerational Trauma? Can It Be Healed?
“Intergenerational trauma is found at the intersection of our biology and psychology.”
DR. MARIEL BUQUE
Trauma doesn’t just affect the individuals who experience it firsthand—it can ripple through families, impacting generations to come. This phenomenon, known as intergenerational trauma, often goes unnoticed, silently shaping behaviors, relationships, and emotional well-being across entire family systems. Even when the original traumatic event is long past, its echoes can still influence how descendants navigate their lives, often without them realizing why.
In this blog post, we’ll explore what intergenerational trauma is, how it manifests in families, and the lasting consequences it can have on emotional and mental health. We’ll also discuss how trauma is passed down, the symptoms that may indicate its presence, and, most importantly, the steps you can take to heal and break the cycle. Whether you’re grappling with your own family history or supporting others on their healing journey, understanding intergenerational trauma is a powerful step toward creating a healthier, more resilient future.
What is Intergeneration Trauma?
Intergenerational Trauma refers to the transmission of trauma effects across generations. This occurs when traumatic experiences or stressors suffered by one generation, such as war, genocide, abuse, or displacement, impact the mental and emotional well-being of their descendants.
Trauma doesn't just affect the individual who directly experiences it. The psychological, behavioral, and even biological consequences of trauma can be passed down to future generations through several pathways:
Behavioral Transmission: Individuals who experience trauma often develop coping mechanisms, emotional responses, or relational patterns that can influence their children. For example, a parent who has endured trauma may struggle with emotional regulation, impacting their parenting style and shaping how their children respond to stress or relationships.
Psychological Transmission: Unresolved trauma can lead to anxiety, depression, or PTSD in one generation, which may make it difficult for them to create a stable, emotionally supportive environment for their children. Children raised in these environments might internalize these issues, affecting their own mental health.
Cultural or Social Transmission: Trauma can be passed down through cultural or societal narratives. This is particularly common in marginalized or oppressed communities, where shared histories of trauma, such as colonization, slavery, or war, become a part of the group’s identity, influencing the collective psyche.
Epigenetic Transmission: Recent studies in epigenetics suggest that trauma can alter the expression of genes related to stress and emotion regulation. These changes may be passed on biologically, making descendants more vulnerable to mental health challenges such as anxiety, depression, or heightened stress responses.
What causes intergenerational trauma?
Intergenerational trauma is caused by traumatic events or experiences that deeply impact one generation and are subsequently passed down to their descendants. It is often caused by large-scale traumatic events that impact individuals, families, and entire communities. These events disrupt safety, identity, family dynamics, and community cohesion, making it challenging to break cycles of trauma without recognition and healing and often leave lasting emotional, psychological, and even biological effects that ripple across multiple generations.
Here are key causes of intergenerational trauma, along with examples:
1. Historical Trauma
Definition: Trauma that affects a large group of people, often tied to a specific historical event or period of systemic oppression, such as war, genocide, slavery, or colonization. The collective suffering endured by a community gets embedded in their identity and passed down through generations.
Examples:
Indigenous Peoples: Many Indigenous communities worldwide, including in Canada, Australia, and the United States, have experienced centuries of colonization, forced assimilation, land dispossession, and cultural suppression. The trauma of these experiences continues to affect newer generations through higher rates of substance abuse, mental health disorders, and loss of cultural identity.
Holocaust Survivors: Descendants of Holocaust survivors often experience heightened levels of anxiety, hypervigilance, and PTSD-like symptoms, even though they did not directly experience the genocide. The trauma of genocide, loss of family members, and displacement often affects their sense of security and emotional well-being.
2. Racism and Systemic Oppression
Definition: Racial trauma is a result of longstanding discrimination, segregation, or institutionalized racism that affects marginalized groups. Even if later generations do not experience the same level of direct violence or discrimination, the legacy of oppression can still deeply affect them.
Examples:
African Americans and the Legacy of Slavery: The descendants of African American slaves in the United States often grapple with intergenerational trauma linked to slavery, segregation, and ongoing racial discrimination. The effects include a persistent sense of injustice, socioeconomic disadvantage, and collective grief, all of which contribute to ongoing disparities in mental and physical health.
Apartheid in South Africa: Descendants of those who lived under apartheid experience ongoing trauma related to the violence, segregation, and disenfranchisement that occurred during this time. Many descendants still feel the effects of social, economic, and political inequalities, leading to mental health struggles and collective trauma.
3. War and Conflict
Definition: Wars, civil conflicts, and military occupations cause profound trauma, including death, displacement, and loss of a sense of safety. Children and grandchildren of war survivors can inherit the emotional scars of these experiences.
Examples:
Vietnam War: Many children and grandchildren of Vietnam War veterans suffer from secondary PTSD. This includes heightened stress responses, anxiety, and emotional detachment that stem from growing up with parents who suffered from combat trauma and PTSD.
Syrian Civil War: Children of refugees from conflict zones such as Syria may inherit trauma associated with displacement, loss of homeland, and witnessing violence. The trauma often extends to second-generation immigrants who struggle with identity, loss of cultural ties, and fear of instability.
4. Childhood Abuse and Neglect
Definition: Trauma from childhood abuse, neglect, or domestic violence can be passed down when the person affected does not process or resolve their trauma, influencing their parenting styles and relationships.
Examples:
Domestic Violence Survivors: Children who grow up in homes where domestic violence occurred may either adopt abusive behaviors or develop anxieties and difficulties in forming healthy relationships. These patterns often get transmitted to future generations, perpetuating cycles of dysfunction and emotional instability.
Parental Substance Abuse: Parents who struggle with addiction, often due to their own unresolved trauma, may create environments of neglect or emotional abuse for their children. These children are at risk of developing similar coping mechanisms, perpetuating substance abuse and related trauma through generations.
5. Forced Displacement and Migration
Definition: People forced to flee their homes due to war, persecution, natural disasters, or economic hardship often endure significant trauma. This includes the emotional toll of losing one’s home, separation from loved ones, and the challenges of adjusting to a new culture or country.
Examples:
Refugees and Asylum Seekers: Refugee families who have fled war or persecution, such as those from Bosnia, Syria, or Afghanistan, carry trauma related to violence, loss, and displacement. Children born in their new country may inherit emotional distress or identity struggles related to their parents' traumatic experiences and the challenges of adjusting to a foreign environment.
Residential Schools in Canada: The Canadian residential school system, where Indigenous children were forcibly removed from their families and placed in institutions aimed at erasing their cultural identity, caused profound trauma. Many survivors transmitted the emotional scars of abuse, loss of language, and disconnection from culture to their descendants.
6. Poverty and Economic Hardship
Definition: Long-term poverty can cause trauma, especially when combined with discrimination, poor living conditions, and a lack of access to basic needs such as healthcare and education. This trauma can persist in families for generations, limiting opportunities and creating cycles of instability.
Examples:
Great Depression: The trauma experienced during the Great Depression had lasting effects on families, even in subsequent generations. Economic hardship, food insecurity, and a fear of scarcity influenced how children and grandchildren approached finances, stability, and security.
Global South Migrant Workers: Families from developing countries who face extreme economic hardship, such as migrant workers from South Asia or Latin America, often transmit trauma linked to exploitation, poor working conditions, and the instability of constantly moving in search of better opportunities.
7. Natural Disasters
Definition: Natural disasters, such as earthquakes, hurricanes, or tsunamis, can cause massive loss of life, displacement, and long-term economic and social disruption. The trauma experienced by survivors can deeply impact future generations.
Examples:
Hurricane Katrina Survivors: The emotional trauma and displacement caused by Hurricane Katrina left many families struggling with PTSD, anxiety, and a sense of loss. Children of survivors may experience heightened fear of instability or distrust in authorities due to the inadequate response during the crisis.
Tsunami in Southeast Asia: Communities in Southeast Asia affected by the 2004 tsunami faced overwhelming grief, loss, and displacement. Children born after the disaster may feel the emotional burden of their parents’ loss, fear of water-related events, or economic instability linked to destroyed infrastructure.
8. Cultural Suppression or Genocide
Definition: The deliberate destruction of a culture, religion, or ethnic group through genocide or cultural suppression can have long-lasting effects on the descendants of those affected, leading to a loss of identity, language, and cultural practices.
Examples:
Armenian Genocide: Descendants of survivors of the Armenian Genocide continue to deal with the loss of cultural identity, family members, and homeland. Many also struggle with the ongoing denial of the genocide, contributing to feelings of unresolved grief and trauma.
Rwandan Genocide: The Rwandan genocide left deep scars not only on survivors but also on their children. These descendants often face emotional challenges tied to the collective grief, loss, and interethnic tension that continues to affect Rwanda’s societal fabric.
What are the symptoms of intergenerational trauma?
The symptoms of intergenerational trauma can manifest in diverse ways, from emotional and psychological struggles to physical health issues and relational difficulties. These symptoms are often rooted in unprocessed trauma from previous generations, and without intervention or healing, they can perpetuate cycles of pain and dysfunction across families and communities. Recognizing these symptoms is the first step toward addressing and healing intergenerational trauma.
Here are some common symptoms:
1. Emotional Symptoms
Chronic Anxiety or Fear: Individuals may experience persistent feelings of anxiety, fear, or hypervigilance, often without a clear cause. This can stem from inherited trauma-related fears or heightened stress responses passed down through the family.
Depression: Feelings of hopelessness, sadness, or emotional numbness can be present. Descendants of trauma survivors may struggle with a sense of meaninglessness, unresolved grief, or a heavy emotional burden, even if they haven’t directly experienced trauma themselves.
Emotional Dysregulation: Difficulty managing emotions, such as sudden outbursts of anger, frustration, or intense sadness, can be common. Trauma survivors often struggle with emotional control, and this may be passed down to their children or grandchildren.
Unresolved Grief: A pervasive sense of loss or sorrow, even when there’s no clear reason, can signal intergenerational trauma. This could be linked to the unresolved trauma or grief experienced by ancestors, such as loss of homeland, culture, or family members.
2. Psychological Symptoms
Post-Traumatic Stress Disorder (PTSD) Symptoms: Although not directly exposed to trauma, individuals may experience PTSD-like symptoms, such as nightmares, flashbacks, or intrusive thoughts. These symptoms can arise from hearing family stories about trauma or internalizing the stress responses modeled by caregivers.
Low Self-Esteem or Identity Confusion: Struggles with self-worth or feeling disconnected from one’s identity can emerge. This may be particularly common in descendants of communities that faced cultural erasure, such as Indigenous peoples, refugees, or those affected by slavery or genocide.
Guilt or Shame: Descendants may carry a deep sense of guilt or shame, often linked to survivor’s guilt passed down from ancestors who survived trauma. They might feel guilt about privileges they have that their ancestors did not or for not being able to "fix" the past.
3. Behavioral Symptoms
Substance Abuse or Addictive Behaviors: Descendants of trauma survivors are at higher risk for substance abuse or other addictive behaviors as a way of coping with inherited emotional pain or stress.
Self-Sabotaging Behavior: Some individuals may engage in patterns of self-sabotage or self-destruction, such as pushing away loved ones, failing to reach potential, or engaging in risky behaviors. These behaviors often stem from feelings of unworthiness, learned helplessness, or unresolved trauma.
Perfectionism or Overachievement: In contrast, some descendants may become perfectionistic or overachievers as a way of coping with deep-seated feelings of inadequacy, fear of failure, or a need to prove their worth.
Hypervigilance or Overprotectiveness: This can show up as being overly cautious, always expecting something to go wrong, or being extremely protective of loved ones. Individuals may feel an overwhelming need to control their environment or keep everyone safe.
4. Relational Symptoms
Difficulty Forming Relationships: Trauma can affect attachment styles, leading to difficulties in forming secure, trusting relationships. Individuals may have trouble opening up to others, experience fear of abandonment, or exhibit emotional detachment in personal relationships.
Parenting Struggles: Parents dealing with intergenerational trauma may unconsciously transmit it to their children through inconsistent or emotionally distant parenting. They may find it hard to connect emotionally with their children or struggle with overprotectiveness due to fears stemming from inherited trauma.
Attachment Issues: Descendants of trauma survivors may develop insecure attachment styles, such as anxious or avoidant attachment. This can manifest in clinginess, fear of abandonment, or difficulty trusting others in close relationships.
5. Cultural and Identity Symptoms
Cultural Disconnection: Descendants of groups affected by cultural trauma (e.g., Indigenous peoples, displaced communities, or those affected by slavery) may experience a loss of connection to their cultural heritage. This disconnection can lead to feelings of alienation, identity confusion, or a desire to reclaim cultural roots.
Internalized Oppression: For marginalized groups, intergenerational trauma can result in internalized racism, sexism, or other forms of self-oppression. This happens when the trauma of systemic oppression is passed down and individuals unconsciously adopt negative beliefs about themselves or their community.
Survivor’s Guilt: This refers to feelings of guilt for not having experienced the same hardships as previous generations. Descendants of trauma survivors may feel unworthy of success or happiness, believing that they must bear the weight of their ancestors' suffering.
6. Physical Symptoms
Chronic Stress or Fatigue: Individuals affected by intergenerational trauma may experience chronic stress or exhaustion, even if their current life circumstances are relatively stable. The inherited trauma can create a persistent feeling of being on edge or drained.
Physical Health Problems: Trauma can also contribute to physical health issues like cardiovascular problems, digestive disorders, autoimmune diseases, and chronic pain. These issues may be connected to the body's long-term response to stress, passed down through epigenetic changes or learned behaviors.
Somatization: Some individuals may experience physical symptoms, such as headaches, stomach aches, or muscle tension, without a clear medical cause. These physical manifestations of stress or anxiety are common in trauma survivors and can be passed down to descendants.
7. Cognitive Symptoms
Difficulty Concentrating: People affected by intergenerational trauma may struggle with focus, attention, or memory. This can stem from a heightened stress response or difficulty managing overwhelming emotions.
Negative Thought Patterns: Persistent negative thoughts or beliefs, such as feelings of helplessness, worthlessness, or fear of the future, can be common. These thought patterns often reflect the unresolved trauma carried by ancestors and can be passed down through family narratives or behaviors.
What are the consequences of intergenerational trauma?
Intergenerational trauma creates a ripple effect that touches many aspects of life, including mental health, family relationships, cultural identity, physical health, and socioeconomic status. The long-term consequences can result in cycles of pain and dysfunction that continue until the trauma is recognized, addressed, and processed through therapy, community healing, and systemic change.
These effects can manifest in several key areas:
1. Mental Health
Increased Vulnerability to Mental Illness: Descendants of trauma survivors often have a higher risk of developing conditions such as anxiety, depression, post-traumatic stress disorder (PTSD), and substance use disorders. These issues may stem from the unresolved trauma of previous generations and are often linked to altered stress responses, learned behaviors, and a lack of emotional regulation passed down through family dynamics.
Emotional Dysregulation: People affected by intergenerational trauma may struggle with processing and expressing emotions, leading to challenges in managing stress, anger, fear, or sadness. This emotional instability often mirrors patterns seen in previous generations who were directly affected by trauma.
2. Family Dynamics and Relationships
Parenting Challenges: Trauma can disrupt the ability of parents or caregivers to provide emotionally supportive and stable environments for their children. Survivors may either become overly protective or emotionally unavailable, impacting how children develop their sense of security, attachment, and self-esteem.
Dysfunctional Relationships: Intergenerational trauma can lead to difficulties in forming and maintaining healthy relationships. Issues like trust, communication problems, or emotional distance can ripple across family members, affecting interpersonal connections not only within families but also in friendships, romantic relationships, and professional settings.
3. Cultural and Identity Struggles
Loss of Cultural Identity: In communities that have experienced collective trauma (e.g., Indigenous peoples, communities affected by genocide or war), trauma can contribute to the erosion of cultural practices, traditions, and language. For descendants, this can lead to a struggle with identity, alienation, or a sense of disconnection from their heritage and community.
Collective Grief and Historical Trauma: Communities that have experienced systemic oppression or historical trauma often carry a shared sense of grief or loss, which can manifest as persistent feelings of injustice, helplessness, or anger. This can influence the emotional landscape of individuals who may feel the weight of past generations' suffering, even if they didn’t experience the original trauma themselves.
4. Socioeconomic Impact
Cycle of Poverty: Trauma, especially when systemic (e.g., colonialism, slavery), can limit educational and employment opportunities for generations. This may lead to cycles of poverty, which further exacerbate stress, mental health issues, and limited access to mental health resources.
Educational Barriers: Trauma can also impact educational achievement. Parents and children dealing with trauma may struggle to focus in school, maintain consistent attendance, or engage in healthy social interactions, which can limit future opportunities for academic or professional advancement.
5. Physical Health
Chronic Health Conditions: The stress of unresolved trauma can contribute to chronic health problems in descendants, such as heart disease, diabetes, or autoimmune disorders. These conditions can be influenced by epigenetic changes, poor coping mechanisms, and lifestyle choices shaped by trauma responses, such as substance abuse or poor diet.
High Stress Response: Intergenerational trauma can cause an overactive stress response system, where descendants are more sensitive to perceived threats or stressors. This "hypervigilance" can lead to physical symptoms like insomnia, digestive problems, or fatigue, often rooted in an overactive fight-or-flight response.
6. Behavioral Patterns
Maladaptive Coping Mechanisms: Descendants of trauma survivors may adopt maladaptive coping strategies, such as substance abuse, self-harm, or other risky behaviors. These behaviors often emerge as attempts to manage unprocessed emotions or to escape from overwhelming feelings of stress or anxiety.
Perfectionism or Avoidance: Some individuals may develop perfectionistic tendencies, driven by a desire to avoid the mistakes or suffering of previous generations. Others may engage in avoidance behaviors, where they struggle to face conflict, emotion, or responsibilities due to deep-seated fear or feelings of inadequacy.
7. Social and Systemic Issues
Disconnection from Community: Intergenerational trauma can contribute to isolation, both within families and communities. Those affected may withdraw from social interactions or community support networks due to feelings of shame, fear, or mistrust, making it difficult to foster social resilience or break cycles of trauma.
Perpetuation of Inequality: In cases where trauma is linked to systemic oppression, like racial or colonial trauma, the effects of this inequality are passed down, continuing to limit access to resources, justice, and opportunities for healing. This can perpetuate cycles of discrimination, marginalization, and inequity in future generations.
8. Epigenetic Impact
Biological Changes: Trauma has been shown to cause epigenetic changes that can affect how genes related to stress and emotional regulation are expressed. This means descendants may have a heightened stress response or be more vulnerable to anxiety and depression, even without direct exposure to the original trauma.
Is it possible to heal from intergenerational trauma?
Yes, it is possible to heal intergenerational trauma, though the process can be complex and requires awareness, support, and intentional effort. Healing often involves breaking patterns of behavior, understanding the root causes of trauma, and finding ways to process both the historical and emotional impacts of that trauma.
Here are several key approaches to healing intergenerational trauma:
1. Acknowledge and Understand the Trauma
Awareness: Healing begins by recognizing that intergenerational trauma exists. Understanding how trauma has impacted previous generations and shaped behaviors, emotional responses, and family dynamics is crucial. This often involves educating oneself about the historical context or personal stories behind the trauma.
Family Dialogue: Open conversations within families can help uncover and process the trauma. While this can be difficult, discussing the effects of trauma openly can break the cycle of silence and denial that often perpetuates it. However, in cases where family members are unwilling to engage, individual exploration of family history can still be beneficial.
2. Get Therapeutic Support
Trauma-Focused Therapy: Therapy, particularly trauma-informed approaches like Cognitive Behavioral Therapy (CBT), Eye Movement Desensitization and Reprocessing (EMDR), or Somatic Therapy, can help individuals work through the emotional and psychological impact of trauma. These methods can assist in identifying trauma responses and developing healthier coping mechanisms.
Family Therapy: Family therapy can be an effective way to address and heal intergenerational trauma. It encourages open communication, fosters understanding, and helps family members support each other in healing.
Cultural Healing Practices: For communities affected by cultural or historical trauma (e.g., Indigenous or marginalized communities), traditional healing practices such as ceremonies, rituals, and reconnecting with cultural roots can be deeply restorative. These practices help restore a sense of identity and belonging.
3. Break Behavioral Cycles
Recognizing Patterns: One of the first steps in healing is identifying unhealthy behaviors or emotional patterns that have been passed down. This can include dysfunctional coping mechanisms like substance abuse, emotional withdrawal, or avoidance of intimacy.
Developing New Coping Strategies: Healing involves learning and practicing healthier ways of coping with stress, fear, and emotional pain. This could mean adopting mindfulness techniques, stress management practices, or healthier communication strategies.
Self-Compassion: A key part of healing is practicing self-compassion. This involves acknowledging that trauma can influence behaviors and feelings, without blaming oneself for inherited emotional pain. Self-compassion helps create space for healing and growth.
4. Build Resilience
Interpersonal Connections: Strong, supportive relationships can provide a foundation for healing. Positive, healthy relationships can help break cycles of emotional isolation or disconnection that often accompany intergenerational trauma.
Community Support: Engaging with supportive communities or peer groups, especially those who have experienced similar traumas, can provide solidarity and shared understanding. Collective healing spaces often provide safety, validation, and empowerment.
5. Reclaim Identity and Cultural Strength
Cultural Reconnection: For those whose trauma is tied to colonization, racism, or cultural suppression, reclaiming cultural identity can be a powerful step in healing. This can involve learning about one’s heritage, language, and traditional practices, or participating in cultural events and rituals.
Empowerment and Advocacy: Engaging in advocacy, activism, or community-based efforts to address historical wrongs can be healing. Working toward social justice or helping others can provide a sense of agency and purpose, which can counter the feelings of helplessness often associated with trauma.
6. Address Epigenetic Factors
Healthy Lifestyle Changes: Research shows that trauma can impact gene expression through epigenetics. While this biological transmission may seem daunting, positive changes in diet, exercise, and stress management can reverse some of these effects. Practicing self-care can help mitigate the long-term physiological impacts of inherited trauma.
Stress Reduction: Reducing stress through mindfulness, meditation, or other stress-relief practices can help manage the physical symptoms of trauma and prevent the passing of heightened stress responses to future generations.
7. Educate Future Generations
Passing on Healthy Coping Skills: By healing one’s own trauma, individuals can model healthier emotional and behavioral responses for their children and future generations. Teaching children emotional regulation, healthy communication, and coping strategies can break the cycle of trauma transmission.
Creating a Supportive Environment: Establishing an emotionally safe, supportive environment for children and family members helps prevent the perpetuation of trauma. This can involve open communication, showing love and support, and modeling resilience in the face of stress.
Healing intergenerational trauma is not only possible but can create profound changes for individuals, families, and entire communities. The process involves recognizing the trauma, seeking therapeutic support, breaking unhealthy patterns, and building resilience. By confronting and processing these deep-rooted wounds, individuals can transform their lives and prevent the trauma from being passed down to future generations. Healing is a journey, but with intentional effort, it can lead to restoration, growth, and a healthier emotional legacy.
Whatever it is, we’re here for you.
Life is uncertain. Jobs are stressful. Parenting is hard. Relationships take work. Families can be dysfunctional. And sometimes, love hurts. When you’re confronted by feelings, events, or issues that are making your life challenging, it’s okay to ask for some help.
