Individuals with cerebral folate deficiency have been observed to have developmental delays with autistic features (e.g., challenges with social communication, sensory processing, and repetitive behaviors), seizures, and problems with movement and coordination
However, when the researchers adjusted for other things , including siblings with autism, the increased risk was no longer statistically significant .[ref][ref] (Note that other researchers point out bias in that paper.[ref]) Another large study published in 2021 involving 73,000 children and mothers found that there was a 19% increase in relative risk of ASD with prenatal acetaminophen exposure.[ref] A 2025 meta-analysis of studies on acetaminophen use during pregnancy and infancy shows that the majority of studies and the higher-quality studies show a positive association between acetaminophen use and ADHD, ASD, or neurodevelopmental disorders.[ref] A couple of things to consider here
Given the extensive experimental data demonstrating health benefits from senescent cell clearance and significant advances in cellular senescence drug discovery, senolytics have emerged as a leading translational geroscience therapy
