In what context did Kennedy link autism to Tylenol use?

Kennedy's link between autism and Tylenol use primarily centers on the context of pregnancy. The argument is based on the hypothesis that the use of acetaminophen (the active ingredient in Tylenol) during pregnancy could potentially affect fetal brain development, leading to an increased risk of autism in children. This association is rooted in concerns about medication exposure in the womb and its implications for the developing nervous system of the fetus. Research has suggested that certain medications, including over-the-counter pain relievers like Tylenol, may have unintended effects during critical periods of brain development. Therefore, discussions around Tylenol and autism often emphasize the timing of exposure – specifically during pregnancy – highlighting the importance of being cautious with medication use during this crucial stage of development.
