In the February 8, 2010 issue of Newsweek, Sharon Begley writes in The Depressing News about Antidepressants of a moral dilemma that arose when a friend shared his desire to "beat his chronic depression once and for all," and asked her if she knew of any research that might help him decide whether a new medication his doctor recommended might actually work. The problem was that she knew of numerous studies, but their results tended to show little difference in the effectiveness of medications and placebos.
Irving Kirsch (University of Connecticut) and other researchers have looked at published drug manufacturer conducted clinical trial reports (1998), and both published and unpublished clinical trial reports (2002), and found that patients on a placebo improved about 75 - 82 percent as much as those on drugs. A report published in the January 6, 2010, issue of The Journal of the American Medical Association found that "the magnitude of benefit of antidepressant medication compared with placebo increases with the severity of depression symptoms and may be minimal or nonexistent, on average, in patients with mild or moderate symptoms."
The question then becomes "How do the drugs work?" Kirsch concluded that "the lion's share of the drugs' effect comes from the fact that patients expect to be helped by them, and not from any direct chemical action on the brain, especially for anything short of very severe depression."
Thus the moral dilemma: "In any given year, an estimated 13.1 million to 14.2 million American adults suffer from chronic depression. At least 32 million will have the disease at some point in their life. Many of the 57 percent who receive treatment (the rest do not) are helped by medication. For the benefit to continue, they need to believe in their pills." To read more . . .
