What studies are saying

In a 2018 study, researchers did a meta-analysis of seven studies involving 132,738 pairs of mothers and children.

People were followed for periods ranging from three to 11 years, depending on the study, using questionnaires, interviews, and self-reports on medication use.

The analysis revealed a 20% higher risk of autism and a 30% higher risk of ADHD for children who had prolonged exposure to acetaminophen in the womb.

However, it noted that taking small amounts of acetaminophen during pregnancy — in one study, for fewer than eight days — didn’t increase risks.

Other studies since then have supported earlier findings that too much acetaminophen may increase one’s risk for autism and ADHD.

I think autism being "caused by" acetaminophen is too strong a statement

IF a pregnant woman takes A LOT of acetaminophen then the risk of autism increases. Less than 8 days is OK. Maybe it's like thalidomide or alcohol... Only has negative effects during certain times of fetal development. But the link isn't 1:1. There are many women who NEVER take acetaminophen who have autistic children, and many who do whose children are fine.

An interesting clue, tho. If they can figure out HOW this happens, they may be able to figure out how autism develops in general.
