ADHD symptoms linked to early childhood exposure to polyfluoroalkyl substances UCPH_Research ADHD childhealth symptoms
By Dr. Liji Thomas, MDMar 28 2023Reviewed by Lily Ramsey, LLM A study published in Science of the Total Environment Journal explores the association of polyfluoroalkyl substances exposure with attention deficit-hyperactivity disorder symptoms.
The most well-known chemical from this group is probably Teflon, used worldwide for nonstick cookware, carpets, food packaging, and firefighting foams. During the first three years of life, children are prone to epigenetic changes mediated by endocrine-disrupting chemicals . Indeed, ADHD is reported to affect over one in fifteen children worldwide, beginning early in life. Epigenetic change may be partially mediated by the effects of heavy metals, phthalates, and possibly PFAS, but the latter is still a research area.
What did the study show? Antibodies eBook Compilation of the top interviews, articles, and news in the last year. Download a free copy The study included almost equal numbers of boys and girls. Six PFAS' were found to be present in over 90% of the children at both two and four years, but the mean concentrations dropped at the later time point. Only two were found more frequently at four years compared to two years, namely, PFPeA and PFTrDA.
When the level of exposure to all six PFAS was used as a summative value, it was observed that the ARS scores increased by a fifth commensurate with a doubling of the summed values. The peak correlation seems to be at the third quartile.
