The finding does not prove causation, but it does suggest that the developing brain may be quietly shaped by the air surrounding it long before any harm becomes visible. At a moment when air quality policy tends to focus on acute, measurable threats, this study asks whether the slo

Millions of US children with ADHD may have experienced preventable neurodevelopmental harm from long-term air pollution exposure.
