MedCram review links acetaminophen to autism through oxidative stress
Start here
A MedCram expert-review video argues that acetaminophen may contribute to autism risk. Metabolised by CYP450 enzymes, roughly 5-9% of the drug converts to the toxic NAPQI, which depletes glutathione and causes oxidative stress that could affect fetal brain development across the placenta. The review cites a majority of 27 studies showing a positive association between acetaminophen and autism, and references a UCL-linked hypothesis that declining long-wave sunlight over nearly 200 years may explain latitude and seasonal patterns in autism prevalence. The claims remain unverified, and the correlation reported in the cited studies does not establish causation. Whether the oxidative-stress mechanism operates in human pregnancy, and whether the sunlight hypothesis holds up, are open questions.
