Intergenerational trauma is a complex phenomenon that can have lasting effects on individuals and their families. My-Linh Le, for example, grew up in a household where her parents’ unresolved traumas manifested as unpredictable anger and explosive reactions to small mistakes. As a child, Le believed this behavior was normal for Vietnamese families, until she found herself reacting in the same way as her mother during a phone call with her boyfriend.
Le’s parents had experienced deep losses, with her father losing his first wife and son in a tragic accident, and her mother leaving a daughter behind in Vietnam out of fear. These unspoken traumas had a profound impact on the emotional landscape of their family and were passed down to Le and her siblings.
Intergenerational trauma is not simply the repetition of traumatic events from one generation to the next. It also includes the increased risk that children have of experiencing the consequences of that trauma, such as post-traumatic stress disorder, mood disorders, behavioral problems, and disrupted attachment.
Research shows that individuals can respond very differently to traumatic events, even within the same family. Factors such as genetics, the severity and chronicity of the trauma, and individual coping mechanisms all play a role in determining how trauma affects an individual.
Understanding how trauma affects the brain can shed light on why it can have such long-lasting effects. Traumatic memories are processed differently in the brain than regular memories, triggering the fight or flight response and flooding the body with stress hormones. When trauma is not addressed or discussed, survivors may struggle to process and understand their experiences.
How families communicate about trauma can also impact how it is experienced and passed down through generations. Complete silence about traumatic events can leave lasting effects on children, as seen in the case of Japanese Americans who never discussed their experiences in internment camps. On the other hand, constantly repeating traumatic stories within a family can also be detrimental, leading to a phenomenon known as “substitute traumatization.”
Insight into intergenerational trauma can help individuals understand the root causes of their struggles and make informed choices about how to break the cycle. By recognizing the impact of trauma on parenting behaviors and relationships, individuals can work towards healing and creating a healthier environment for future generations.
