Oct 20, 2025 Acetaminophen's alleged link to autism is unpacked with a focus on the importance of data interpretation. Dr. K explains autism as a complex spectrum influenced by numerous genetic and environmental factors. He highlights that rising diagnosis rates may stem from better detection rather than increased actual risk.

Episode notes
Autism Is A Spectrum Of Many Causes
- Autism is a neurodevelopmental spectrum shaped by many small, compounding factors.
- It represents millions of individual presentations we group because they appear similar.
Rising Rates Reflect Better Detection Too
- Reported autism rates have risen partly because we diagnose it better today.
- Increased detection doesn't necessarily mean a single new cause is driving prevalence.
Tylenol Shows Small Relative Risk Increase
- Some meta-analyses show acetaminophen use in pregnancy associates with a 20–30% increased autism risk.
- That relative increase translates to a small absolute risk change for most individuals.
