Study affirms genetic link in depression

By Staff Writer

An individual’s ability to rebound from trauma and avoid depression may have a lot to do with their genes, according to new study published in the Archives of General Psychology that challenges previous skepticism of a genetic link to depression.

Since the early 2000s, scientists have believed that there is likely a hereditary underpinning in many cases of depression. However, that assertion was called into question following the release of a 2009 study, which indicated that this may not be the case.

However, researchers from University of Michigan have revived the idea of a genetic link in depression. For the study, they examined the results of 54 previous investigations that looked into the role that genes play in the regulation of the neurotransmitter serotonin, which is associated with feelings of well-being.

The team found that individuals who have a certain type of serotonin gene were less able to cope with trauma and more likely to develop depression.

Researchers said that their findings could help medical professionals identify individuals who are most likely to suffer from depression and enable them to find appropriate treatment.
