There is mounting talk of a link between Paracetamol/Acetaminophen/Tylenol and autism.

A study published in JAMA in 2024 concluded that there is no evidence for that claim (https://jamanetwork.com/journals/jama/fullarticle/2817406):

Question: Does acetaminophen use during pregnancy increase children’s risk of neurodevelopmental disorders?

Findings: In this population-based study, models without sibling controls identified marginally increased risks of autism and attention-deficit/hyperactivity disorder (ADHD) associated with acetaminophen use during pregnancy. However, analyses of matched full sibling pairs found no evidence of increased risk of autism (hazard ratio, 0.98), ADHD (hazard ratio, 0.98), or intellectual disability (hazard ratio, 1.01) associated with acetaminophen use.

Meaning: Acetaminophen use during pregnancy was not associated with children’s risk of autism, ADHD, or intellectual disability in sibling control analyses. This suggests that associations observed in other models may have been attributable to confounding.

It tends to be poor scholarship imho.

Autistic moms are more likely to have chronic illness, sensory issues, auto immune issues, etc thus are more likely to be taking medications. In the end, the autistic mom just passes her autistic genes to the baby.
