Over the past two decades, the use of antidepressants has skyrocketed. One in 10 Americans now takes an antidepressant medication; among women in their 40s and 50s, the figure is one in four.
Experts have offered numerous reasons. Depression is common, and economic struggles have added to our stress and anxiety. Television ads promote antidepressants, and insurance plans usually cover them, even while limiting talk therapy. But a recent study suggests another explanation: that the condition is being overdiagnosed on a remarkable scale.
The study, published in April in the journal Psychotherapy and Psychosomatics, found that nearly two-thirds of a sample of more than 5,000 patients who had been given a diagnosis of depression within the previous 12 months did not meet the criteria for major depressive episode as described by the psychiatrists’ bible, the Diagnostic and Statistical Manual of Mental Disorders (or D.S.M.).
….Ironically, while many patients in the United States are inappropriately diagnosed with depression, many who actually have it suffer without treatment. Dr. Mark Olfson, a professor of clinical psychiatry at Columbia University Medical Center, noted that from the time they develop major depression, it takes Americans eight years on average to seek care.
Diagnosing depression is an inherently subjective task, said Dr. Jeffrey Lieberman, the president of the American Psychiatric Association.
