Sir: Table 2 of the recent ACADEMIC HIGHLIGHTS on preventing recurrent depression in patients with major depressive disorder (MDD)1 reports that, despite maintenance treatment with antidepressants, recurrences may occur in 6% to 66% of patients with MDD (vs. 23% to 100% of patients with MDD who received placebo). This apparent high risk of recurrence in MDD has been attributed to placebo response, nonadherence, and tachyphylaxis (explained as an emotional blunting due to selective serotonin reuptake inhibitors, not as a true recurrence). 1 Along with a possible loss of effect of antidepressants in the long run,2 the problem of the high proportion of bipolar depression, especially the depression of bipolar II disorder, misdiagnosed as MDD3–5 is not reported as a possible cause of recurrences.​
