The final nail in the mercury-autism hypothesis?

Another study. Another failure to link thimerosal to a higher risk of autism. Can we just bury the claim that thimerosal in vaccines causes autism, already?

Terrible Anti-Vaccine Study, Terrible Reporting

One of my goals in writing for this blog is to educate the general public about how to evaluate a scientific study, specifically medical studies. New studies are being reported in the press all the time, and the analysis provided by your average journalist leaves much to be desired. Generally, they fail to put the study into context, often get the bottom...

The genetics of autism

Autism and autism spectrum disorders (ASDs) actually represent a rather large continuum of conditions that range from very severe neurodevelopmental delay and abnormalities to the relatively mild. In severe cases, the child is nonverbal and displays a fairly well-characterized set of behaviors, including repetitive behaviors such as “stimming” (for example, hand flapping, making sounds, head rolling, and body rocking.), restricted behavior and...

Nine differences between “us and them,” nine straw men burning

I’ll start this post by admitting right up front: I blatantly stole the idea for the title of this post from Mark Crislip’s most excellently infamous post Nine questions, nine answers. Why? Because I really liked that post and felt like it. Also, there seems to be something about the number nine among anti-vaccine zealots: Nine “questions.” Nine circles of hell. Nine...

Andrew Wakefield Fights Back

Dr. Andrew Wakefield was almost single-handedly responsible for frightening the public about a possible association between autism and the MMR vaccine. His alarmist recommendations directly led to lower vaccination rates and a resurgence of measles to endemic levels in the UK. The MMR/autism interpretation of his 1998 article in The Lancet was retracted by 10 of his 12 co-authors. The article itself...

Bogus Diagnostic Tests

A few years ago a friend asked me to comment on advice given to her adult daughter by a psychiatrist whom she’d consulted for depression. The psychiatrist had recommended testing samples of saliva and urine for hormone and neurotransmitter levels, the results of which would likely indicate a need for supplements to correct deficiencies or imbalances. According to the psychiatrist, who had...

Social Factors in Autism Diagnosis

There is no question that the incidence and prevalence of autism are on the rise. Starting in the early 1990s and continuing to today, there has been a steady rise in the number of children diagnosed with autism. Prior to 1990 the estimates of autism prevalence were about 3 per 10,000. The most recent estimates from the CDC and elsewhere now have...

Steven Higgs: Another antivaccine reporter like Dan Olmsted in the making?

April is National Autism Awareness Month, and as of today April is nearly half over. Do you notice anything different compared to the last couple of years? I do. Can you guess what it is? The anti-vaccine movement’s usual suspects haven’t been all over the mainstream media, as they usually are this time every year, often as early as April 1 or...

Autism Onset and the Vaccine Schedule – Revisited

This week on Science-Based Medicine I wrote an article about a new study looking at the onset of autism symptoms, showing that most children who will later be diagnosed with autism will show clear signs of autism at 12 months of age, but not 6 months. This is an interesting study that sheds light on the natural course of autism. I also...

Yet another nail in the coffin of the myth that the MMR vaccine causes autism

Another study, another refutation of the myth that the MMR vaccine causes autism. The same as it ever was. Antivaccine activists won't listen. Also the same as it ever was.
