Autism and Prenatal Vitamins
Science has found no evidence that vaccines cause autism; but the true cause(s) of autism have not yet been determined. So far the available evidence has pointed towards a largely genetic cause with possible interaction with environmental factors. A new study supports that interpretation. It also supports previous evidence that autism is triggered prior to birth, rather than at the time of...
Anti-vaccine warriors vs. research ethics
Three weeks ago, the anti-vaccine movement took a swing for the fences and, as usual, made a mighty whiff that produced a breeze easily felt in the bleachers. In brief, a crew of anti-vaccine lawyers headed by Mary Holland, co-author of Vaccine Epidemic: How Corporate Greed, Biased Science, and Coercive Government Threaten Our Human Rights, Our Health, and Our Children, published a...
Delusional Parasitosis
A new study looks into the disorder known as delusional parasitosis, which many dermatologists believe is the true diagnosis behind the controversial disorder called Morgellon’s disease. Morgellons is a controversial disorder because many patients with symptoms believe they are being infected by an unusual organism, causing excessive itching, but no offending organism has been found. Some patients claim they have strange fibers...
Fungus yields new prescription drug for multiple sclerosis
The following post appeared earlier this week at my Chemical & Engineering News CENtral Science blog, Terra Sigillata. For some odd reason – perhaps this week’s frantic academic schedule of commencement activities – it was not highly read there. I thought that our Science-Based Medicine readers would appreciate it because this new prescription drug is derived from a family of fungi that...

When you can’t win on science, invoke the law…
Late last week, the anti-vaccine underground was all atwitter. The reason was the announcement of an impending press conference, scheduled for yesterday at noon in Washington, DC that proclaimed: Investigators and Families of Vaccine-Injured Children to Unveil Report Detailing Clear Vaccine-Autism Link Based on Government’s Own Data Report Demands Immediate Congressional Action Directors of the Elizabeth Birt Center for Autism Law and...
Autism Prevalence Higher than Thought
Crossposted from NeuroLogica Blog Over the last 20 years the prevalence of autism (now part of autism spectrum disorder, ASD) has been increasing. The medical community is largely agreed that this increase is mostly due to expanding the diagnostic category and greater efforts at surveillance. There remains some controversy over whether or not these factors explain all of the measured increase, or...
Chemical castration of autistic children leads to the downfall of Dr. Mark Geier
One of the most persistent myths is one that’s been particularly and doggedly resistant to evidence, science, clinical trials, epidemiology, and reason. It’s also a myth that I’ve been writing about a long time. Specifically, I’m referring to the now scientifically discredited myth that the mercury-containing thimerosal preservative that used to be in quite a few childhood vaccines causes autism. The myth...
“Motivated reasoning,” alternative medicine, and the anti-vaccine movement
One theme that we at Science-Based Medicine keep revisiting again and again is not so much a question of the science behind medical therapies (although we do discuss that issue arguably more than any other) but rather a question of why. Why is it that so many people cling so tenaciously to pseudoscience, quackery, and, frequently, conspiracy theories used by believers to...
CCSVI Update
I have been following the story of Dr. Zamboni, an Italian vascular surgeon who claims that multiple sclerosis (MS) is primarily caused by blockages in the veins that drain blood from the brain. This results in backup of blood in the brain, leading to inflammation around the blood vessels and MS. He sought to find the cause and cure for MS because...
EMDR and Acupuncture – Selling Non-specific Effects
The scientific approach to understanding the world includes the process of carefully separating out variables and effects. Experiments, in fact, are designed specifically to control for variables. This can be especially challenging in medicine, since the body is a complex and variable system and there are always numerous factors at play. We often characterize the many variables that can influence the outcome...
