Autism incidence higher than expected

Four in every 1,000 children aged 6 to 12 in China have autism, an incidence that experts say is higher than expected.

The figure has been uncovered in the first national epidemiological investigation into the prevalence of autism spectrum disorder.

Symptoms include differences and disabilities in many areas including social communication skills, motor skills, and sometimes intellectual skills as well as unusual responses to sensory input such as unusual sensitivity to light and sound, or sensory cravings.
