A new study published by the University of Pittsburgh School of Medicine reports that researchers in the United States have discovered what they believe are early signs that indicate children’s (children’s food) vulnerability to depression. The study demonstrates for the first time that children who are prone to major depression have abnormal growth hormone production and that their brain chemistry may be more disrupted than normal. Researchers from the University of Pittsburgh School of Medicine tested 119 children. They found that children who were prone to depression due to a family history of psychiatric disorders produced “significantly” less growth hormone than control children after being administered growth hormone-releasing hormone (ghrh). Boris Biermacher, an associate professor at the University of Pittsburgh School of Medicine, said, “These findings suggest that a reduction in growth hormone production in children receiving ghrh is a marker for depression.”
