As reported by Guardian, a simple computer test can help to detect children suffering from depression or anxiety disorders. The test is ideal for children in the first two years of secondary school and duration of screeing puplis is about twenty minutes.
For the study, the researchers drew on 238 boys and girls aged 15 to 18, from schools in Cambridge and Suffolk. Each had a genetic test to determine the forms of a certain gene they had inherited from their parents. The gene, called 5-HTTLPR, helps regulate the brain chemical, serotonin, and comes in short and long versions.(Guardian)
