To the Editor:
Refractory depression is common in
clinical practice. At least 30% of patients fail to respond to
initial antidepressant therapy.1
In patients who have failed 1
course of antidepressants, there is evidence from 9 randomized
controlled trials suggesting that approximately 50% of
treatment-refractory patients do respond to lithium augmentation
compared with placebo (p < .001).2
