intergenerational transmission of trauma

When we focus solely on the negative consequences of trauma, we may overlook the positive. When we generalize, we lose sight of the individual as well as the individual ways in which people interpret and make meaning from or find meaning in their life experience. Every survivor had a history and a personality before the horrific event, during it, and after. Consequences are unpredictable most people will recover from trauma though everyone, depending on context and at different times, can experience either vulnerability or resilience. Kellermann reminded us that vast majority of survivors and their children function well. The most frequent diagnosis is depression followed by anxiety which may be accompanied by substance abuse.ĭr. Novac stressed that PTSD is actually the least common diagnosis, though the most severe and needing the most treatment. For those of us who work with survivors of any sort of trauma, Dr. We tend to use the term “PTSD” for any negative consequence of trauma. Once an alarm is triggered, the organism doesn’t calm down-and it turns out children of people diagnosed with PTSD are more likely to develop PTSD themselves if experiencing trauma. But people diagnosed with PTSD show below normal levels of cortisol. For most people, this then triggers the release of cortisol which has an initial calming effect. Instead it releases a flood of adrenaline. In people who’ve been traumatized, the amygdala doesn’t wait for the stimulus to be evaluated. Andrei Novac explained, when a person perceives a potential threat, the impulse goes first through the frontal lobe which evaluates whether or not the alarm needs to be heeded. Today there’s a lot of interest in the biological or epigenetic factors, the way the biological stress response in the mother is transmitted to the child during pregnancy. For example, survivors may be overprotective while others have no patience with any sign of weakness. The second generation feels the effects even if the mechanism is not clear. Tactics that helped a person survive there may carry over in habits here. On the other hand, sometimes there’s too much talk of the traumatic experience, repetitive and obsessive. When the parent’s trauma remains silenced, psychoanalytic theory would say the repressed experience is transmitted as a shadow over the child, and it’s the child who must now process the experience. He asks about content, process, and timing: what the child learned, how it was told, and when-and how the child reacted to this knowledge. Natan Kellermann pointed out, even within a single family, not every child inherits the burden of secondary trauma. Instead we have to look at the individual, at the interplay of biological and psychosocial factors.Īs Dr. How is it transmitted? There’s no single explanation. This installment, however, will briefly share theories about the transgenerational effects of trauma. Politicians are complicit in the slaughter. Millions of parents and kids affected as well, as they realize, once again, that there is no place of safety, that in our society guns have more rights than human life. Hundreds more traumatized by what they’ve gone through. Right now? I’ve just watched footage of still another school shooting. In that spirit, I’ve tried to apply what I heard that day very broadly. doi:10.“When a crime against humanity occurs, all of humanity is affected,” said Christie Tcharkhoutian, speaking at the symposium, Inheriting Genocide: Intergenerational Transmission of Trauma.
