Why is paramecetol safety so perplexing?
Another study on acetaminophen (known as paramecetol in Denmark) on probability of having a child with autism, this one with over 1.5 million pregnant women, 31k who were exposed to acetaminophen. The HHS Secretary is calling it “garbage in and garbage out” because it showed no link, but in fact,...

Wildfires, air pollution, autism and the EPA response
Air pollution, specifically one part of air pollution called PM 2.5 (named for the size of the crud in the air pollution) has been linked to autism. It’s also been tied to cancer, heart disease, asthma, obesity, and premature births. Air pollution typically comes from industrial sources and car...

Contextual Factors in Autism: What took us so long?
Contextual factors, or external factors, are environmental influences and can impact not just a diagnosis but the life course of a person with autism and their families. A recent commentary by autism researchers around the world highlights the importance of these factors and provides resources on...

More about the environmental influences in autism
New research points to a previously understudied but fascinating mechanism by which environmental factors may lead to autism: it’s called the “GABA/glutamate switch” which is a critical period in development when certain cells turn from turning on cell activity to turning them off. These...

A potential biomarker to AID, not MAKE, a diagnosis
The media has just called another biological marker a “diagnostic test”, when in this case, it was always intended to be an aid, not a test itself. It involves using baby hair strands to look a variation in metabolism of certain chemical elements across time. Remarkably, it showed similar results...

What causes autism? Genetics or the Environment? Or maybe both?
Is it genes or is it the environment? or is it a combination? This question has plagued researchers and scientists and caused a lot of confusion in families about what caused their own or their child’s ASD. This week we review the mechanisms by which de-novo mutations could be the work of gene x...

From being high to being aggressive
There are many many potential factors that influence a diagnosis of ASD that have been underexplored, and recreational drugs are one of them. Of course it would never explain all the cases of ASD, not one singular thing does, but does cannabis consumption during pregnancy lead to an increased...

Beyond what scientists already know about environmental factors
This week the ASF Podcast explores two ways to better understand the environmental influences in ASD diagnosis: 1. through potential cost savings of avoided cases of ASD due to reduced air pollution and 2. by studying pre-conception exposures going back as far as the grandparents exposure. These...

Age of parents and ASD. It’s complicated.
Questions have loomed around the finding of an increased risk of parents having a child with ASD if they are under 20 or over 35. Of course not every parent who is really young or older will have a child on the spectrum and plenty of those between those ages also have children on the … Continue...

Genes and Environment, Genes and Environment. Go together like aging and retirement.
Twins with autism, where either one or both is diagnosed, is crucial to understand the role of genetics and the environment to both autism diagnoses and now, autism traits. In a study this week, researchers using data from the California Twins Study examined the genetic and environmental…
