New Insights Could Help Predict and Prevent Depression

New understanding could help identify people with an increased risk of developing depression. The findings of the study suggest that people with the highest genetic propensity are more likely to be treated in a psychiatric hospital for depression.

In a new study, researchers from the Danish iPSYCH project demonstrate that people with the highest genetic propensity are over two and a half times as likely to be treated in a psychiatric hospital for depression compared to people with the lowest propensity. This knowledge could be utilized to strengthen prevention efforts for those who are at risk.

In Denmark, 15.5 percent of woman and nine percent of men receive treatment for depression at a psychiatric hospital at some stage of their lives. Depression is a common but very serious condition which is very costly for both the individual and society as a whole.

Researchers have now completed a study in which they followed 34,500 Danes for up to 20 years and measured their genetic risk for developing depression.

"The study showed that the risk of being treated for depression at a psychiatric hospital was more than two and a half times higher for people with a high polygenic risk score," explains professor at iPSYCH and contributor to the study Esben Agerbo.

Depression � A Holistic Approach-Signs, Symptoms and Treatment
Depression is a common disorder and many worldwide suffer from depression. Early recognition of symptoms and signs of depression can help in taking a holistic approach to the management of depression.

Polygenetic means that the disease is not connected to only one disease gene, but to many genes. Put another way, it means there are many genes that determine whether a person is predisposed to developing depression.

Easier to Identify People

Depression - Types, Causes, Symptoms, Diagnosis, Treatment
Depression is one of the most common mental disorders affecting approximately 340 million people in the world. No one is immune from depression - it occurs in people of all social classes, all countries and all cultural settings.

"We know that depression is partly determined by genetic factors, and today it's possible to measure the genetic propensity directly - rather than having to rely on family history as a way of guessing at genetic disposition for developing depression," explains Esben Agerbo.

The polygenetic score was not related to factors such as mild, moderate, severe or psychotic symptoms, treatment setting or age at the first hospital visit, which could mean that these aspects are determined more by environmental factors.

"Our hope is that by utilizing genetic information in conjunction with known risk factors in the environment, we will be able to develop better methods to identify people who are at risk of developing depression," says postdoc at iPSYCH, Katherine L. Musliner, who is behind the study.

However, the results also show that the relationship between genetics and mental illness is complex. There is no ' depression gene,' and even those with the highest genetic propensity will not necessarily develop depression.

"The ability to identify people with an increased risk of developing depression is useful, because it will make it possible for us to target preventative efforts towards the people who will benefit most from them," says Katherine L. Musliner.
