Trauma Across Generations

Trauma is often discussed as an individual experience, but many researchers and clinicians now recognize that its effects can echo through families and communities across generations.

Reed’s Star explores how trauma can be carried, repeated, and sometimes transformed across generations within families, institutions, and communities shaped by war, instability, addiction, silence, and survival.

This page will continue to develop with plain-language explanations, selected research, historical context, and resources related to intergenerational trauma.

What Is Trauma?

Trauma isn't defined solely by what happened. Its effects can involve how a person’s nervous system, emotions, memories, relationships, and sense of safety respond afterward.

Post-Traumatic Stress Disorder (PTSD)

Post-traumatic stress disorder, or PTSD, can develop after experiencing or witnessing a traumatic event. Its effects may include intrusive memories or reminders of the event, avoidance, changes in mood and thinking, and heightened alertness or reactivity.

Not everyone who experiences trauma develops PTSD, and people may respond to similar experiences in very different ways.

Complex PTSD (CPTSD)

Complex PTSD, or CPTSD, is associated particularly with prolonged or repeated trauma. In addition to symptoms associated with PTSD, it can involve persistent difficulties with emotional regulation, a person's sense of self, and relationships with others.

CPTSD is recognized as a diagnosis in the World Health Organization’s International Classification of Diseases (ICD-11). It is not currently classified as a separate diagnosis in the American Psychiatric Association’s DSM-5-TR.

Intergenerational Trauma

Intergenerational trauma, sometimes called transgenerational trauma, refers to the ways the effects of trauma can continue beyond the person who originally experienced it.

Researchers, clinicians, and many families have observed that trauma can influence emotional patterns, relationships, behaviors, stress responses, parenting styles, addiction, silence, fear, and survival strategies across generations. This does not mean trauma is destiny, but it may shape the environments and coping patterns children grow up around.

Trauma can emerge from many experiences, including war and military environments, abuse or neglect, addiction, domestic violence, institutional systems, instability, poverty, sudden loss, or long-term fear and uncertainty.

In some families and communities, trauma is openly discussed. In others, it may remain hidden behind silence, emotional distance, hypervigilance, anger, addiction, or survival-focused behavior that becomes normalized over time.

Researchers continue exploring how trauma may affect emotional health, stress regulation, relationships, and even physical health across generations. At the same time, resilience, compassion, creativity, education, storytelling, supportive relationships, and community can also carry forward.

Epigenetics and Trauma

Epigenetics is the study of changes in how genes are expressed without changing the underlying DNA sequence. Researchers are investigating whether trauma and prolonged stress may influence biological processes in ways that could have effects across generations. This remains an evolving area of research, particularly in humans.

Understanding trauma is not about assigning blame. It is about recognizing patterns, increasing awareness, and creating opportunities for understanding, resilience, and healing.
