flag Higher prenatal PFAS exposure linked to altered brain development in children by age five, per a Nordic study.

flag A new study links higher maternal PFAS levels during pregnancy to changes in children’s brain structure and function by age five, finding associations with key regions like the corpus callosum, occipital lobe, and hypothalamus, as well as altered brain connectivity. flag The research, based on 51 pregnant women in Finland and Sweden, shows certain PFAS types—especially those with carboxylic acid groups—had stronger effects. flag While PFAS are known to cross the placenta and blood-brain barrier, it remains unclear if the observed changes are harmful, beneficial, or neutral. flag Further research is needed to understand long-term impacts.
