Offspring of trauma survivors show stress biological changes without direct exposure

Evidence

Yehuda, Rachel, James Schmeidler, Milton Wainberg, Karen Binder-Brynes, and Tamar Duvdevani. “Vulnerability to Posttraumatic Stress Disorder in Adult Offspring of Holocaust Survivors.” American Journal of Psychiatry 155, no. 9 (1998): 1163–1171. doi:10.1176/ajp.155.9.1163. The paper establishing that adult children of Holocaust survivors showed significantly elevated rates of PTSD and PTSD vulnerability, and dysregulated cortisol profiles consistent with HPA axis dysregulation, compared to demographically matched Jewish adults without Holocaust family history. This 1998 publication — eighteen years before the FKBP5 paper — established the intergenerational transmission claim at the physiological and epidemiological level, identifying the Holocaust offspring cohort as a model system for studying the biological transmission of stress effects before the term “epigenetics” had entered the trauma literature. — , The Rod and the Child, 7129
