I've never had any of those parental instincts, that I at least assume that people tend to have. Some friends have told me that they have this urge to have children that I just can't relate to. Which is probably for the better for a plethora of reasons; traumatization can be passed down genetically, I have a tendency to both dissociate and panic which could potentially be extremely harrowing for a child that's attuned to me and well... They wouldn't be allowed to see their grandmother.
Trans-generational transmission of trauma has been shown, in many academic studies, to exist. It is easy to see in the children and grandchildren of former concentration camp inmates, but it is not passed down genetically. Here are some relevant parts:
The people who actually survived will often display arterial hypertension, chronic pains, digestive complains and a lack of affect as well as depression and feelings of guilt. Ofc this is in addition to the classic PTSD symptoms.
Common symptoms in the second generation (the children) are role-switching (feeling to have been the actual victim) with additional feelings of guilt and shame. They see themselves as "living memorial candles" and act accordingly. They have a higher psychological vulnerability and higher dependence. Neuroses, anxiety, fears and personality disorders are more frequent if compared to the general population. A reduced general resilience to stress is also common.
The third generation often displays an increased fear of dangers with emotional coldness but striving to stay close to the parents. Eating disorders are frequently found with an underlying feeling of anger and regret. They are often unable to unlink the events of the Second World War to unrelated current events. Other frequent feelings are an increased sense of responsibility and of minimising and regarding their own problems as worthless.
Nonetheless, the third generation of concentration camp survivors, compared to their parents and the general population, displays a better aptitude for intergenerational dialogue and have a need to help other people. They are often politically active and engaged in human rights protection. They tend to be more thankful for what they have, more prone to heroism and positive pride. They can transform their vulnerability in a positive manner and are more unlikely to be directly subject to post-traumatic distress syndrome.
Laboratory findings include a higher cortisol level and cortisol enzymes, a genetically altered expression of mRNA and methylation of the FKBP5 gene.
(ok this last paragraph may not be interesting).
This is so you know.
However this is in concentration camp survivors, which is a BIG trauma for those who were there. Regarding an individual trauma, imho it would need to be properly assessed, but those general findings are spot-on. Note no studies yet on the 4th generation. There aren't many.
And since you might ask:
