Everybody’s Doing It
One argument that often comes up when skeptics and proponents of so-called complementary and alternative medicine (CAM) debate is the question of the popularity of various CAM practices. Advocates of CAM often claim these practices are widely used and growing rapidly in popularity. Obviously, CAM proponents have an interest in characterizing their practices as widely accepted and utilized. Even though the popularity of an idea is not a reliable indication of whether or not it is true, most people are inclined to accept that if a lot of people believe in something there must be at least some truth to it. The evidence against this idea is overwhelming, but it is a deeply intuitive, intransigent notion that can only rarely be dislodged.
It might therefore be useful to get some idea of whether or not the claims of great popularity for CAM treatments are true. If they are not, fruitless debates about the probative value of such popularity could potentially be avoided, and it might be possible to diminish the allure associated with the belief that “everybody’s doing it.” Read more »

For the last week I have had a cold. I usually get one each winter. I have two kids in school and they bring home a lot of viruses. I also work in a hospital, which tends (for some reason) to have lots of sick people. Although this year I think I caught my cold while traveling. I’m almost over it now, but it’s certainly a miserable interlude to my normal routine.
One thing we can say for certain about the common cold — it’s common. It is therefore no surprise that there are lots of cold remedies, folk remedies, pharmaceuticals, and “alternative” treatments. Finding a “cure for the common cold” has also become a journalistic cliche — reporters will jump on any chance to claim that some new research may one day lead to a cure for the common cold. Just about any research into viruses, no matter how basic or preliminary, seems to get tagged with this headline. (It’s right up there with every fossil being a “missing link.”)
But despite the commonality of the cold, the overall success of modern medicine, and the many attempts to treat or prevent the cold — there are very few treatments that are actually of any benefit. The only certain treatment is tincture of time. Most colds will get better on their own in about a week. This also creates the impression that any treatment works — no matter what you do, your symptoms are likely to improve. It is also very common to get a mild cold that lasts just a day or so. Many people my feel a cold “coming on” but then it never manifests. This is likely because there was already some partial immunity, so the infection was wiped out quickly by the immune system. But this can also create the impression that whatever treatment was taken at the onset of symptoms worked really well, and even prevented the cold altogether.
What Works
There is a short list of treatments that do seem to have some benefit. Nonsteroidal anti-inflammatory drugs (NSAIDs), like aspirin, ibuprofen, and naproxen, can reduce many of the symptoms of a cold — sore throat, inflamed mucosa, aches, and fever. Acetaminophen may help with the pain and fever, but it is not anti-inflammatory and so will not work as well. NSAIDs basically take the edge off, and may make it easier to sleep. Read more »

Three recent stories lead me to my opening topic for the year: The value of open-mindedness. This characteristic — a state of receptiveness to new ideas — affects how we perceive and process information. It’s a quality I look for in my doctors, and which I admire especially in older people.
Piece #1 — On the brain’s maturity, flexibility and “cognitive fitness”
For the first piece, I’ll note a Dec 31 op-ed piece that appeared in the New York Times: This Year, Change Your Mind, by Dr. Oliver Sacks, the neurologist and author. In this thoughtful essay, he considers the adult brain’s “mysterious and extraordinary” power to adapt and grow: “I have seen hundreds of patients with various deficits — strokes, Parkinson’s and even dementia — learn to do things in new ways, whether consciously or unconsciously, to work around those deficits.”
With appropriate and very-real respect, I question Sacks’ objectivity on this subject — he’s referred some of the most outstanding (i.e. exceptional) neurological cases in the world. And so it may be that his careful reports are perfectly valid but not representative; for most of us, the adult brain’s capacity to establish new circuitry for language learning or music appreciation may be limited. What his stories do show is that unimaginably strange things happen in our brains, at least occasionally. And maybe we should just accept that and take notes (as he does so carefully), and keep an open mind. Read more »

If you go to the website of the National Center for Complementary and Alternative Medicine (NCCAM), you’ll find that one of its self-identified roles is to “provide information about CAM.” NCCAM Director Josephine Briggs is proud to assert that the website fulfills this expectation. As many readers will recall, three of your bloggers visited the NCCAM last April, after having received an invitation from Dr. Briggs. We differed from her in our opinion of the website: One of our suggestions was that the NCCAM could do a better job providing American citizens with useful and accurate information about “CAM.”
We cited, among several examples, the website offering little response to the dangerous problem of widespread misinformation about childhood immunizations. As Dr. Novella subsequently reported, it seemed that we’d scored a point on that one:
…Dr. Briggs did agree that anti-vaccine sentiments are common in the world of CAM and that the NCCAM can do more to combat this. Information countering anti-vaccine propaganda would be a welcome addition to the NCCAM site.
In anticipation of SBM’s Vaccine Awareness Week, I decided to find out whether such a welcome addition has come to fruition. The short answer: Nope. Read more »

I’ve been warning folks about this for years – and alas, fake medicine and quackery has finally oiled its way into the healthcare reform bills. We are in the midst of a growing primary care shortage, and on the brink of vastly expanding health insurance coverage without increasing the supply of physicians and nurses. How will our country solve the supply/demand mismatch? Potentially by allowing people without appropriate training in science and medicine to become your “medical home.” That’s right – your next doctor or nurse may be someone with an online degree in snake oil salesmanship.
I know it’s hard to believe… But please read this press release (reproduced below) for more information – and call your Senator to complain. Maybe we’ll be able to get these sections removed before a bill passes? Read more »
