Brain training may ward off depression in vulnerable teens

This study tests whether computer-based training that targets emotional memory or attention can prevent major depression in young people who have depressive symptoms or have recovered from a depressive episode. Participants are randomly assigned to one of three active training programs or a placebo, completing daily sessions for two weeks, with a booster at six months. They are followed for five years to see if they develop a major depressive episode and to identify cognitive factors that predict depression onset.
