Some researchers have also pointed to the high incidence of depressed children in families with a depressed parent and suggested that depression is a learned response to stress. That is, children respond to stress in their lives in much the same way that they have seen their parents do. When their parents react to pressure and frustration with depression, the children will do the same. However, it is important to note that the increased risk of childhood depression in the offspring of depressed adults probably also has to do with inheriting a genetic vulnerability to develop the disorder. In other words, just as the parent was susceptible to depression for biochemical reasons, so is the child. For that reason, when a child is evaluated for depression, the mental health professional will always ask about family history of mood disorder.
