If the biological roots of such ailments could be identified, treatments might follow, or at least tests that could reveal a person’s risk level. In the 1990s, researchers focused on genes that might possibly be responsible for mental distress, but then hit a wall. Choosing so-called candidate genes up front proved to be fruitless. In...
