Children of mothers with clinical depression are at three times greater risk to develop depression themselves than are their low-risk peers. Researchers are working to understand the neural underpinnings of the risk, and some studies have shown altered brain processing of reward in at-risk children as young as 6. An outstanding question remains as to whether children with a maternal history of depression have a biological predisposition to blunted neural reward responding or whether it depends more on social factors. Now, new work finds those dampened responses depended on maternal feedback, suggesting the latter.
