Stress and brain development

Chronic stress during pregnancy has been a rather neglected topic, with some suggesting that there is no value in quantifying its effects on the fetus, newborn and beyond, because what is the point. The evidence is overwhelming for profound effects of stress during pregnancy on neurodevelopment. I and many others maintain that early identification of fetuses of mothers affected by chronic stress harbor the chance of early therapeutic intervention before or early after birth to help reduce long-term neurodevelopmental cost.

We and others have studied several avenues of such short and long term cost, ranging from programming of increased risk for autism spectrum disorder to Parkinson's and Alzheimer's. Early tackling of chronic stress' impact on brain development is well worth it, but it is a long game which poses its challenges in pursuing this line of research. We hope the research papers listed below contribute to the big picture and point to some solutions how to detect the effects of chronic stress early and how to tackle its sequelae when the butterfly effect is still small. This paper has been particularly inspirational to me from standpoint of connecting the notions of chronic stress and metabolic cost.
