Hidden Triggers That Could Unravel the Mystery of Autism Spectrum Disorder

9. Low Birth Weight

The survival rate of premature infants has increased dramatically in recent decades, leading to more research on long-term developmental outcomes. Studies show that infants weighing 2,000 grams (4.4 pounds) or less at birth have a fivefold higher autism prevalence in adulthood. Neurodevelopmental disorders are more common among those born prematurely with low birth weight, likely due to altered brain development and increased medical stress during early life. One study used a screening questionnaire rather than pre-existing diagnoses, revealing previously unrecognized autism traits among participants, particularly those with strong social skills.

10. No Connection To Vaccines

There is no scientific evidence linking vaccines to autism—none. The study that originally suggested a connection was later exposed as fraudulent, and its lead author lost his medical license. Since then, extensive research has debunked this claim, with dozens of studies finding no correlation between vaccines and autism. The CDC has specifically studied thimerosal, a preservative once used in vaccines, and found no link to autism. Despite this, vaccine hesitancy persists, fueled by misinformation. Protecting public health through vaccination is essential, and continued efforts to combat myths surrounding autism and vaccines remain critical.
