About 1 percent of the world population has autism spectrum disorder. ( https://child-testing.com/autism-spectrum-disorder/ ) Prevalence in the United States is estimated at 1 in 68 births. Prevalence of autism in U.S. children increased by 119.4 percent from 2000 (1 in 150) to 2010 (1 in 68). Autism is the fastest-growing developmental disability. There is no cure for ASD as it is a genetic and thus lifelong condition. Some examples of famous icons believed to have a form of ASD include Bill Gates, Susan Boyle, Sir Isaac Newton, Albert Einstein. Research has found that most standard IQ tests do not tap the true cognitive ability of many children on the autistic spectrum.
