Possible genetic link to depression

Scientists believe they have discovered a genetic link to one of the world's most common and costly mental illnesses.

They are calling it the first solid evidence that variations on some people's genes may cause depression.

Also, in a rare occurrence, a British led international team's findings of a DNA region linked to depression has been replicated by another team from the u-s. They were studying an entirely separate group of people.

Both groups found exactly the same region in two separate studies.

Scientists are hoping the findings will bring them closer to developing more effective treatments for patients with depression since currently available medicines for depression only work in around half of patients.

Both studies are published in the Journal of Psychiatry.
