Quizplus · Accepted Answer

Autism spectrum disorder is a neurodevelopmental disorder with a complex etiology, involving a combination of genetic, neurological, and environmental factors. The exact causes of ASD are still not fully understood, but recent research points to a combination of genetic and environmental factors. It is not caused by vaccinations. The prevalence of ASD has increased over the past decade, although it is unclear whether this is due to an actual increase in cases or greater awareness and diagnosis. As of 2018, the Centers for Disease Control and Prevention (CDC) estimated that 1 in 59 children in the United States has ASD. The percentage of students with disabilities who have ASD varies by state, but it is generally around 7 to 8 percent.
