The discovery of genes that are linked to the crippling condition throws up exciting new possibilities for its successful treatment
Depression runs in families, we know. But it is only very recently, and after considerable controversy and frustration, that we are beginning to know how and why. The major scientific discoveries reported last week by the Psychiatric Genomics Consortium in Nature Genetics are a hard-won breakthrough in our understanding of this very common and potentially disabling disorder.
If your parents have been depressed, the chances that you have been or will be depressed are significantly increased. The background risk of depression in the general population is about one in four – each of us has a 25% chance of becoming depressed at some point in our lives. And if your parents have been depressed, your risk jumps by a factor of three.
