Polycyclic aromatic hydrocarbons — usually shortened to PAH — are a component of air pollution. And new research suggests they may raise the risk of ADHD in children whose mothers are exposed to them.

ADHD is often treated with stimulants, which some researchers and parents are concerned could limit children's growth. But new research may relieve those concerns.
