Doubts Arising About Claimed Epigenetics of Holocaust Trauma
Holocaust and other trauma had been reported to be inheritable, but it's impossible to tease out the influence of genetic modification from that of horrific stories.
Is it even possible that the effects of trauma, such as experienced during the Holocaust or other horrifying events, can be inherited? That a father or mother can pass post-traumatic stress to their childen, through egg or sperm? Recent studies have insisted they can – but now doubts are emerging about the conclusions reached from the data.
Over decades, studies have linked post-traumatic stress disorder in Holocaust survivors with an increased risk of anxiety, depression, and PTSD in their children. More recently, research has suggested that such trauma may be transmitted via epigenetic means, which means: we can pass on not only our genes, but how our genes are expressed.
