A recent study has revealed that exposure to air pollution may increase the risk of children developing autism spectrum disorder (ASD). The research indicates that pregnant women are particularly vulnerable to common air pollutants, which can have detrimental effects on the fetal brain during a critical period of development. The study highlights potential dramatic impacts on neurodevelopment.
According to Professor Haitham Amal, a lead author of the study, various neurological disorders, including ASD, may be linked to exposure to pollutants. The timing of exposure during prenatal development is crucial as vulnerability increases at this stage.
The study suggests that fine particulate matter and nitrogen oxides, commonly found in the atmosphere due to transportation and fossil fuels, have a significant impact on young brains. Individuals with a genetic predisposition to autism are especially at risk, as genetics may play a role in up to 80% of autism cases.
Scientists believe that pollutants can cross the placenta and affect fetal brain development by disrupting nerve communication, chemical reactions, and hormonal systems. While autism affects a small percentage of the global population, researchers are still investigating its causes, with some suggesting a combination of genetic and environmental factors.
The researchers hope that their findings will prompt healthcare professionals to implement protective measures for pregnant women in highly polluted areas. Read more:
