  1. 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 …
  2. The curious case of Poul Thorsen, fraud and embezzlement, and the Danish vaccine-autism studies
    If there’s one thing about the anti-vaccine movement, it’s all about the ad hominem attack. Failing to win on science, clinical trials, epidemiology, and other objective evidence, with few exceptions, anti-vaccine propagandists fall back on attacking the person instead of the evidence. F…
  3. Freeways, autism, and correlation versus causation
    I have a love-hate relationship with epidemiology. On the one hand, I love how epidemiology can look for correlations in huge sample sizes, sample sizes far larger than any that we could ever have access to in clinical trials, randomized or other. I love the ability of epidemiology to generate hypot…
  4. The final nail in the mercury-autism hypothesis?
    PROLOGUE: BAD LUCK AND BAD TIMING Two and a half years ago, very early in the history of this blog, I wrote one of my usual logorrheic (although I prefer the word “comprehensive”) posts entitled Mercury in vaccines as a cause of autism and autism spectrum disorders (ASDs): A failed hypot…
  5. Dedicated to Jake Crosby and Age of Autism…
    Yes, despite the best efforts of Jake Crosby, Age of Autism, and AoA commenters, I’m still standing. Stay tuned tomorrow for as much of the story as I can tell you. …
  6. 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, incl…
  7. Autism One: The yearly antivaccine autism “biomed” quackfest begins
    In the world of the anti-vaccine underground, there is one time of the year that looms large. Over the last few years, this time has generally come right around the end of May, usually coinciding with the Memorial Day weekend and the unofficial beginning of the summer vacation season here in the U.S…
  8. 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 rece…
  9. Vaccinations and autism: are we number 1?
    It has been alleged by Great Minds such as Jenny McCarthy that the US recommends far more vaccinations than other countries.  Her precise statement was, “How come many other countries give their kids one-third as many shots as we do?” She put this into the context of wondering if our current va…
  10. 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…
