For the past 10 years, the Autism rate in the United States has risen by a staggering 175%. These rates have intrigued and concerned scientists, prompting many studies and research in order to understand the possible causes of this alarming trend. One particular study done by Israeli scientists discovered a correlation between genetic predisposition to autism and exposure to four commonly found pollutants.
The four pollutant
The four pollutants pointed out were small particles of dust and smoke, sulfur dioxide, nitrogen oxides, and ozone. These pollutants are often associated with respiratory issues and have now been linked to potential impact on brain development, specifically in the risk of Autism Spectrum Disorder.
Senior Author of the study, Amal, explains that pregnant mothers and their unborn children are most vulnerable to these pollutants. This, of course, doesn’t mean that environmental factors are the sole contributors to ASD; it’s already established that genetics also play a major role in the development of this disorder. It’s a combination of factors, including genetics and environment, that influence the development of Autism Spectrum Disorder in children.
How pollutants affect the brain
As for the exact mechanism by which these pollutants disrupt brain development, scientists haven’t reached a concrete conclusion but have proposed potential pathways for further research. Previous studies conducted by Harvard researchers found that exposure to fine particulate matter during early childhood and prenatal periods increased the risk of ASD by 64% and 31%, respectively.
It’s a concerning fact, especially considering that pollution levels are on the rise. Just recently, the American Lung Association’s latest report, State of the Air 2024, revealed that an alarming 131.2 million people in the United States, making up 39% of the population, live in areas with unhealthy air pollution levels.
California is actually home to four of the top five most polluted cities in the United States, including Bakersfield and Sacramento, as mentioned previously.
Future plans
Hopefully, this study serves as a wake-up call for policymakers to prioritize environmental regulations and policies that aim to reduce pollution levels. More research is needed to fully understand the exact impact of air pollution on brain development and its role in ASD. Still, this study brings us one step closer to understanding this complex disorder. Do you or your loved one need help related to Autism Spectrum Disorder?
