Possible association between air pollution exposure, especially at young age, and alterations in brain structure

A study published in the journal Environmental Pollution has found an association, in children aged 9‑12, between exposure to air pollutants in the womb and during the first 8.5 years of life and alterations in white matter structural connectivity in the brain. The greater the child's exposure before age 5, the greater the brain structure alteration observed in preadolescence. The study was led by the Barcelona Institute for Global Health (ISGlobal).
