Researchers have found structural differences in the brains of children at high risk for depression due to parental depressive history. Depression is a common and debilitating mental health condition that typically arises during adolescence. While the causes of depression are complex, having a parent with depression is one of the biggest known risk factors.
According to the study, about one-third of the children were in the high-risk group because they had a parent with depression.
The research found that in the high-risk children, the right putamen a brain structure linked to reward, motivation, and the experience of pleasure- was smaller than in children with no parental history of depression.
