More than two decades after the September 11, 2001 attacks, researchers continue to discover new impacts caused by the largest terrorist attack in recent US history. A recent study suggests that the psychological effects of the trauma experienced by survivors, first responders, and people directly exposed to the tragedy may even reach the next generation, influencing the mental health of children and descendants.
Furthermore, the researchers highlight that extreme traumatic experiences can leave deep marks not only on those who experienced the event but also on the family environment and emotional patterns transmitted over time. For this reason, experts have begun to investigate more closely the so-called intergenerational or transgenerational trauma.
Study analyzes consequences that can span generations
The September 11 attacks left nearly 3,000 dead and thousands of survivors with lasting physical and emotional consequences. Since then, various studies have been following first responders, victims’ families, and people who were near the World Trade Center during the attacks.
Now, new analyses indicate that part of this suffering may also reflect in subsequent generations. According to researchers, children of people deeply affected by major traumas may show greater vulnerability to emotional problems, anxiety, stress, and mental health-related difficulties.

What is intergenerational trauma?
Intergenerational trauma occurs when the psychological effects of a traumatic event influence behaviors, emotions, and family relationships across generations.
Moreover, this transmission does not necessarily occur through direct genetic inheritance. In many cases, it is related to how parents and family members deal with traumatic experiences and how these experiences shape the environment in which children grow up.
Researchers are also investigating possible biological and epigenetic mechanisms that may contribute to this process, although there are still scientific debates about the extent of this phenomenon in humans.
Attacks left deep marks on American society
The September 11 attacks profoundly transformed the United States.
Besides the human losses, the episode caused changes in the country’s politics, national security, and social behavior. Many people developed post-traumatic stress disorder (PTSD), depression, anxiety, and other psychological issues that persisted for years.
Therefore, experts consider September 11 one of the most striking examples of collective trauma in contemporary history.
Children can feel effects even without experiencing the event
One of the most surprising aspects of the study is the possibility that descendants of traumatized people may exhibit emotional effects even without having directly experienced the tragedy.
Additionally, behaviors related to fear, insecurity, hypervigilance, and stress can be transmitted within the family environment over the years.
In this way, traumatic experiences end up influencing the emotional construction of new generations.
Research on transgenerational trauma gains strength
In recent years, scientific interest in transgenerational trauma has increased significantly.
Besides studies related to September 11, researchers analyze situations involving wars, genocides, domestic violence, slavery, natural disasters, and forced displacements. In many of these cases, persistent psychological impacts have been identified among descendants of survivors.
Consequently, the topic has become an important area in psychology, psychiatry, and neuroscience.
Treatment and support remain fundamental
Experts emphasize that the transmission of trauma effects is not inevitable.
On the contrary, psychological support, family support, and appropriate interventions can significantly reduce emotional impacts over time. Furthermore, recognizing and treating old traumas helps to break cycles of suffering that could perpetuate across generations.
Therefore, researchers argue that access to mental health should remain a priority for people exposed to extreme events.
Science seeks to understand the long-term effects
Although there are still many unanswered questions, studies on the psychological legacy of September 11 show that traumatic events can have much more lasting consequences than previously imagined.
Moreover, the research reinforces the importance of understanding how extreme experiences affect not only individuals but also entire families and communities. As new evidence emerges, scientists hope to develop more effective strategies to prevent and treat the effects of trauma across generations.
