Study: Maternal anxiety affects the fetal brain

"These findings are pretty much in keeping with previous studies that show disturbances in connections reported in the years and decades after birth of children born to women with anxiety," says Dr. De Asis-Cruz. "That suggests a form of altered fetal programming, where brain networks are changed by this elevated anxiety even before babies are born."
Whether these effects during gestation themselves linger or are influenced by postnatal care is still unclear, adds Dr. Limperopoulos. Further studies will be necessary to follow children with these fetal differences in neural connectivity to determine whether these variations in neural circuitry development can predict future problems. In addition, it's unknown whether easing maternal stress and anxiety can avoid or reverse these brain differences. Dr. Limperopoulos and her colleagues are currently studying whether interventions that reduce stress could alter the trajectory of fetal neural development.
In the meantime, she says, these findings emphasize the importance of making sure pregnant women have support for mental health issues, which helps ensure current and future health for both mothers and babies.
"Mental health problems remain taboo, especially in the peripartum period where the expectation is that this is a wonderful time in a woman's life. Many pregnant mothers aren't getting the support they need," Dr. Limperopoulos says. "Changes at the systems level will be necessary to chip away at this critical public health problem and make sure that both mothers and babies thrive in the short and long term.
