A new study has suggested to Chrysalis Not For Profit that depression and anxiety can be genetic; that parents can potentially pass the risk of developing these mental health conditions onto their children.
Depression and anxiety
Figures from the Royal College of Psychiatrists show that one in five people will experience depression at some point in their lifetime. Meanwhile, data collected by mental health information portal Mental Healthy, indicates that 16% of the UK population will experience anxiety at any one time.
A study published in the journal ‘Proceedings of the National Academy of Sciences,’ has shed some light on why people experience depression and anxiety. The research indicates that parents pass the risk of developing these conditions onto their children.
Origins of mental health conditions
Experts at the UW School of Medicine and Public Health conducted an experiment with nearly 600 young rhesus monkeys, which are evolutionary cousins of humans. They used brain imaging to measure anxiety-related behaviours when the monkeys were confronted with a situation that has been known to cause anxiety in children, e.g. being confronted by a stranger who refuses to make eye contact.
This experiment showed that family history can be used to explain 35% of variation in anxiety-like tendencies. It also found that there are three areas of the brain located in the brain-stem, which could be connected to hereditary mental illness. These are the prefrontal cortex (used by humans for higher-level reasoning), the limbic brain fear centre and the amygdala.
Neural underpinnings of inherited anxiety
The School’s Chair of Psychiatry, Ned Kalin, served as the senior author of the research. He was quoted by the Independent explaining: “Over-activity of these three brain regions are inherited brain alterations that are directly linked to the later life risk to develop anxiety and depression.
“Basically, we think that to a certain extent, anxiety can provide an evolutionary advantage because it helps an individual recognize and avoid danger, but when the circuits are over-active, it becomes a problem and can result in anxiety and depressive disorders.” Kalin concluded by commenting that “this is a big step in understanding the neural underpinnings of inherited anxiety and begins to give us more selective targets for treatment.”
