This week the @WSJ reported that the upcoming MAHA report will include acetaminophen (also known as Tylenol in the United States, although it is used all over the world) use during pregnancy as a cause of autism. Acetaminophen is used in about 7.5 % of pregnant women. This is one of many environmental exposures that had previously been investigated in association with an autism diagnosis, but then disproven following rigorous and large scale studies with the right design. For example, is it acetaminophen or fever during pregnancy? Is it acetaminophen or some sort of underlying genetic susceptibility? This week’s ASFpodcast explores the association and what pregnant women should know.

Identifying subtypes for autism and narrowing down the heterogeneity of symptoms has been considered the holy grail of autism research.  If one person with autism is not like another person with autism, can they at least be put into groups to speed up studies into causes, intervention and services?  And how?  This podcast explains two different studies that used the same statistical method but different children with autism to identify different groups.  One of the things that helped define these groups was verbal ability and IQ.  For the first time, comorbid symptoms like medical issues and psychiatric diagnoses  are being taken into account.  Already, this approach is helping scientists better understand why fever improves symptoms in some people with autism.
