A recent systematic review in PLOS One raised the question whether acupuncture and other alternative therapies are as effective as antidepressants and psychotherapy for depression. The authors concluded
differences were not seen with psychotherapy compared to antidepressants, alternative therapies [and notably acupuncture] or active intervention controls
or put it differently,
antidepressants alone and psychotherapy alone are not significantly different from alternative therapies or active controls.
There are clear messages here. To consumers: Why take antidepressants with their long delay and uncertainty in showing any benefits–but immediate side effects and potential risks–when a few sessions of acupuncture work just as well? To promoters of acupuncture and alternative therapies: you can now cite an authoritative review in the peer-reviewed PLOS One as scientific evidence that your treatments is as effective as scary antidepressants and time-consuming psychotherapy when you make appeals to consumers and to third-party payers.
The systematic review had five co-authors, of whom three have been involved in previous meta-analyses of the efficacy of antidepressants. However, fourth author Irving Kirsch will undoubtedly be the author most recognizable to consumers and policymakers, largely because his relentless media campaign claiming antidepressants are essentially worthless, no better than placebo. For instance, in an interview with CBS 60 Minutes Irving Kirsch: The difference between the effect of a placebo and the effect of an antidepressant is minimal for most people.

Marcia Angell has written a two-part article for The New York Review of Books: “The Epidemic of Mental Illness: Why?” and “The Illusions of Psychiatry.” It is a favorable review of 3 recent books:
and an unfavorable review of the most recent version of the Diagnostic and Statistical Manual of Mental Disorders, DSM-IV-TR. It paints a disturbing picture of psychiatry. It raises a number of serious concerns but it borders on psychiatry-bashing, a sport that I deplored in a previous post. (more…)
Antidepressant drugs have been getting a bad rap in the media. I’ll just give 3 examples:
- On the Today show, prominent medical expert Tom Cruise told us Brooke Shields shouldn’t have taken these drugs for her postpartum depression.
- In Natural News, “Health Ranger” Mike Adams accused pharmaceutical companies and the FDA of covering up negative information about antidepressants, saying it would be considered criminal activity in any other industry.
- And an article in Newsweek said “Studies suggest that the popular drugs are no more effective than a placebo. In fact, they may be worse.”
Yet psychiatrists are convinced that antidepressants work and are still routinely prescribing them for their patients. Is it all a Big Pharma plot? Who ya gonna believe? Inquiring minds want to know:
- Are antidepressants more effective than placebo?
- Has the efficacy of antidepressants been exaggerated?
- Is psychotherapy a better treatment choice?
The science-based answers to the first two questions are clearly “Yes.” The best answer to the third question is “It depends.” (more…)
If there’s one thing about the so-called “complementary and alternative medicine” (CAM) movement that I’ve emphasized time and time again, it’s that its adherents have a definite love-hate relationship with science. They hate it because it is the single greatest threat to their beliefs system and the pseudoscience that underlies it. At the same time, they crave the legitimacy that science confers. They crave it not because they have any great love for science. Quite the contrary. It is simply that they recognize that science actually delivers the goods. Of course, they believe that they deliver the goods too, but they come to this belief not through science but rather through all the cognitive shortcomings and biases to which humans are prone, such as confusing correlation with causation, confirmation bias, not recognizing regression to the mean, and being fooled by the placebo effect. Whether it’s through a misunderstanding of science or less innocent reasons, they go to great lengths to torture it into superficially appearing to support their claims through a combination of cherry-picking of studies that seem to support them and misrepresenting ones that don’t, discussions of which abound right here in this very blog.
The other thing I’ve emphasized about the CAM movement is that, even more than scientific credibility, they crave legitimacy. To them, however, science is but one pathway to legitimacy, because, unlike practitioners of science-based medicine, they are more than willing to bypass science to obtain the legitimacy–or at least the appearance of the legitimacy–they so crave. If it means doing an end run around science by trying to hijack the Obama health insurance reform bill that is currently being negotiated to resolve the differences between the Senate and House versions, so be it. Indeed, earlier this year, I described how Senator Tom Harkin has tried to promote CAM through the National Center for Complementary and Alternative Medicine (NCCAM) and trying to insert provisions into the bill that would mandate that government-subsidized insurance exchanges pay for CAM. Meanwhile, prominent CAM advocates have been carpet-bombing the media with dubious arguments in support of CAM, as in when Deepak Chopra, Rustum Roy, Dean Ornish, and Andrew Weil teamed up in different combinations to promote the idea that CAM is all about “prevention” and that science-based medicine, in all its reductionistic evil, is nothing more than pushing pills.
They’re at it again.
Psychiatry is arguably the least science-based of the medical specialties. Because of that, it comes in for a lot of criticism. Much of the criticism is justified, but some critics make the mistake of dismissing even the possibility that psychiatry could be scientific. They throw the baby out with the bathwater. I agree that psychiatry has a lot of very dirty bathwater, but there is also a very healthy baby in there that should be kept, cherished, nourished, and helped to grow – scientifically.
Common criticisms in the media
- We are over-medicating our children, producing a generation of drugged zombies.
- We are using medication indiscriminately for people who don’t fit the diagnosis (i.e. antidepressants for people who only have normal mood fluctuations and life problems).
- Antidepressants lead to violence and suicide.
- Psychotropic medications all have terrible side effects.
- Antidepressants are no better than placebo.
- Psychotherapies are no better than talking to a friend.
- Electroconvulsive therapy (ECT) is a barbaric, damaging assault with no redeeming value.
- And we all remember how Tom Cruise attacked Brooke Shields on the issue of postpartum depression.
Thomas Szasz: Mental illness is a myth
Thomas Szasz goes even further: he rejects the whole concept of mental illness and considers it a plot to interfere with people’s human rights. He says:
- Psychiatric diagnoses are not valid because they are based on symptoms rather than on objective tests. (Steve Novella has pointed out that there are other well-established diagnoses like migraine that cannot be verified by any objective tests.)
- Mental illness is a myth: unusual behavior does not constitute a disease.
- Psychiatric diagnoses are an arbitrary construct of society to facilitate control of individuals whose behavior does not conform.
- Involuntary commitment is never justified even for the protection of the patient: patients always have the right to refuse treatment even if that means they will die. (more…)
