Babies Still Affected From 9/11
Scientists at Mount Sinai School of Medicine and the University of Edinburgh studied the relationship between maternal posttraumatic stress syndrome disorder (PTSD) symptoms and salivary cortisol levels in 38 women and their infants. Mothers who experienced symptoms of PTSD in response to 9/11 had lower cortisol levels compared to mothers who did not develop this condition. Moreover, approximately one year after birth, the babies of mothers who had developed PTSD symptoms had significantly lower cortisol levels compared to that in babies of mothers who developed only minimal symptoms. This decrease in cortisol levels among the infants was similar to their mothers' hormonal response to PTSD. Since lower cortisol levels in relation to maternal PTSD were most apparent in babies born to mothers who were in their third trimester on 9/11, the data implicate the possibility of in utero effects as contributors to a putative biological risk factor for PTSD.
"The findings suggest that mechanisms for transgenerational transmission of biologic effects of trauma may have to do with very early parent-child attachments," says Dr. Yehuda, "and possibly even in utero effects related to cortisol programming."
