What we know about autism's causes
"What is autism? Autism isn't a disease. It's a complex developmental condition better known as autism spectrum disorder that affects different people in different ways. It can include delays in language, learning or social and emotional skills. For some people, profound autism means being nonverbal and having intellectual disabilities, but the vast majority of people with autism experience far milder effects."
"Autism rates have been going up for decades There are two main reasons. First, the definition of autism broadened as scientists expanded their understanding of its wide range of traits and symptoms. That led to changes in the criteria doctors use to diagnose autism and improvements in screening. At the same time, parents increasingly sought a diagnosis as autism became better known and schools began offering educational services they hoped could help their kids."
White House officials suggested that Tylenol use during pregnancy may contribute to rising autism rates in the U.S., and President Trump commented that he thinks an answer has been found. Health Secretary Robert F. Kennedy Jr. pledged earlier to determine autism's cause by September, a claim that baffled brain experts. Experts say autism has no single cause and that rhetoric may overlook decades of genetic and environmental research. Autism spectrum disorder is a complex developmental condition affecting language, learning, social and emotional skills. Diagnostic criteria broadened and screening improved, raising prevalence estimates from about 1 in 150 to about 1 in 31 children. The increase is not primarily among the most profound cases.
