Air pollution linked to brain changes in teens, even at safe levels.
Exposure to common air pollutants like particulate matter, nitrogen dioxide, and ozone may harm brain development in adolescents, a study by OHSU researchers finds.
Analyzing data from nearly 11,000 children, the study links early exposure to these pollutants with atypical cortical thinning in brain regions critical for mood, memory, and executive function.
Though no immediate symptoms appear, the changes may disrupt long-term cognitive and emotional development, potentially affecting attention, learning, and behavior.
The effects were seen even at pollution levels within current safety standards, raising concerns about air quality's impact on youth mental and neurological health.
