Identifying autistic kids as early as possible is very important so that appropriate clinical interventions and upbringing can have the most beneficial effect.
Now a new study in the Proceedings of the National Academy of Sciences has shown that analyzing the unique signature of children’s pre-speech vocalizations can be a pretty good way to identify potential cases of autism. Read more »

I can’t speak for anyone else who blogs here at Science-Based Medicine, but there’s one thing I like to emphasize to people who complain that we exist only to “bash ‘alternative’ medicine.” We don’t. We exist to champion medicine based on science against all manner of dubious practices. Part of that mandate involves understanding and accepting that science-based medicine (SBM) is not perfect. It is not some sort of panacea. Rather, it has many shortcomings and all too often does not live up to its promise.
Our argument is merely that, similar to Winston Churchill’s invocation of the famous saying that “democracy is the worst form of government except all the others that have been tried,” science-based medicine is the worst form of medicine except for all the others that have been tried before. (Look for someone to quote that sentence soon.) It’s not even close, either. Read more »

There’s a noteworthy column in Psychiatric Times, “Normality Is an Endangered Species: Psychiatric Fads and Overdiagnosis,” by Allen Frances, M.D. He was chair of the task force that worked on the Diagnostic & Statistical Manual — DSM-IV — one edition of the “bible of psychiatry.” He is professor emeritus of psychiatry at Duke University School of Medicine. There’s a lot of common ground between what Dr. Frances writes and what Dr. Daniel Carlat (the subject of an earlier blog posting) writes about. Dr. Frances is concerned about the directions that might be taken in the authoring of DSM-V, now underway.
Excerpts:
“Fads in psychiatric diagnosis come and go and have been with us as long as there has been psychiatry. The fads meet a deeply felt need to explain, or at least to label, what would otherwise be unexplainable human suffering and deviance. In recent years the pace has picked up and false “epidemics” have come in bunches involving an ever-increasing proportion of the population. We are now in the midst of at least 3 such epidemics–of autism, attention deficit, and childhood bipolar disorder. And unless it comes to its senses, DSM5 threatens to provoke several more (hypersexuality, binge eating, mixed anxiety depression, minor neurocognitive, and others). Read more »

In the latest media barrage on autism, fertility treatment has come into question as a possible cause for this increasingly common developmental disorder. The reason is two research abstracts recently presented at the International Meeting for Autism Research in Philadelphia.
One study assessed the history of IVF (in vitro fertilization) among 574 children evaluated at a special center for autism in Israel. The researchers found that 10% of the group diagnosed as autistic had had IVF, compared to a background rate in the overall population which they quote as 3.5%. Not surprisingly, maternal age was higher in the IVF group and the rate of prematurity was higher in the autistic children.
The second study was a look into a pre-existing database — the Nurse’s Health Study — which collects data from a cohort of nurses over time. The researchers compared the reproductive history reported by women who also reported having a child with autism and compared it to that of women who did not report having an autistic child. Of those with autistic children, 48% reported infertility with 34% having used ovulation inducing drugs, compared with 33% and 24%, respectively, in women without autistic children, a difference that was statistically significant when controlled for maternal age and self-reported pregnancy complications.
A Time article getting a lot of media play calls the results of the second study “some of the strongest evidence to date” linking autism to fertility treatment. Unfortunately, that’s just not true. Read more »

I came across a TED video of Michael Specter’s talk about the dangers confronting us as the war against science progresses. Here’s TED’s description of the video:
Vaccine-autism claims, “frankenfood” bans, the herbal cure craze — they all point to the public’s growing fear (and, often, outright denial) of science and reason, says Michael Specter. He warns the trend spells disaster for human progress.

It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…

Book Review: Is Empathy Learned By Faking It Till It’s Real?
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
The Spirit Of The Place: Samuel Shem’s New Book May Depress You
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
Eat To Save Your Life: Another Half-True Diet Book
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
