Cleaner Air May Protect Children’s Eyesight and Slow Myopia

New research reveals that cleaner air may protect children’s eyesight and help slow the rise of myopia, especially in younger children. Using machine learning, scientists found that children living in less polluted areas had better vision, even after accounting for genetics and screen time.

Air Pollution Linked to Toxic Protein Clumps Driving Lewy Body Dementia

A new study reveals a molecular link between fine particulate air pollution (PM2.5) and Lewy body dementia, a devastating neurodegenerative condition. By combining human epidemiological data and animal experiments, researchers showed that PM2.5 exposure triggers toxic clumps of alpha-synuclein in the brain, similar to those seen in patients.

Air Pollution May Impair Language Skills, Brain Health

Long-term exposure to nitrogen dioxide and fine particulate matter may harm cognitive health, particularly language ability, in older adults. In a new study of individuals aged 65 and over, those living in England’s most polluted areas consistently scored lower on cognitive assessments, especially in language-based tasks.

Air Pollution Linked to Autism Risk During Developmental Stages

A new review highlights how air pollution, particularly fine particles and nitrogen oxides, can elevate autism risk by disrupting critical brain development processes. Key mechanisms, including nitrosative stress, neuroinflammation, and neurotransmitter disruptions, reveal how prenatal and early childhood exposure impact neurological health. Small particles, such as PM2.5, can cross the placenta, potentially harming fetal brain development, especially for genetically predisposed individuals.

Air Pollution Linked to Poor Learning and Memory in Kids

Exposure to ammonium nitrate, a component of fine particulate pollution from agricultural emissions, is associated with reduced learning and memory in children. This type of pollution, also linked to neurodegenerative risks in adults, highlights how air quality impacts brain health across ages.

Air Pollution Linked to White Matter Changes in Children

A recent study links exposure to air pollutants during pregnancy and childhood with lasting changes in the brain's white matter microstructure, affecting cognitive development through adolescence. The research, which followed over 4,000 participants, found that pollutants like PM2.5 and nitrogen oxides (NOx) were associated with developmental delays in white matter integrity.

Air Pollution Exposure Linked to Parkinson’s Risk: Study Identifies U.S. Hot Spot

Exposure to air pollution has previously been linked to an increased risk of Alzheimer's disease. Now, researchers provide preliminary data linking air pollution to an increased risk of Parkinson's disease. The new study, which considered geographical data and diagnosis rates for Parkinson's, revealed those who live in the Mississippi-Ohio River Valley are at particularly higher risk of being diagnosed with Parkinson's.

An Association Between Exposure to Air Pollution in the First 5 Years of Life and Alterations in Brain Structure

Assessing a child's exposure to air pollution on a monthly basis from conception to the age of 8.5, researchers found the greater the exposure to air pollution before the age of 5, the greater the alteration in brain structure by preadolescence.

Air Pollution and Stress Alter Brain Development and Social Behavior

Air pollution along with housing insecurity and stress during pregnancy leads to an increased risk of autism-like social behaviors and differences in neural anatomy in male mice offspring. Researchers believe the changes could be due to the immune system.
