Placebo power: Depressed people who respond to fake drugs get the most help from real ones

When it comes to treating depression, how well a person responds to a fake medicine may determine how well they'll respond to a real one, new research finds. Those who can muster their brain's own chemical forces against depression, it appears, have a head start in overcoming its symptoms with help from a medication. But those whose brain chemistry doesn't react as much to a fake medicine, or placebo, struggle even after getting active drug.
