Autism spectrum disorder in children
Among 14 U.S. states with areas that were monitored for autism spectrum disorder in 2022, California had the highest prevalence rates of autism spectrum disorder (ASD) among children aged eight years. In 2022, California’s prevalence rate was estimated to be **** cases per 1,000 children, while the rate was about **** cases per 1,000 children in Indiana. ASD is more common among male than female children, with an estimated ** male cases per 1,000 children and ** female cases per 1,000 children in California in 2022.Â
Limitations in a child with autism can vary between individuals and develop over time. In California, the median age of diagnosis among children with an ASD diagnosis with an IQ greater than 70 was **** of age, in comparison to **** for children with an ASD diagnosis and an IQ less than or equal to 70, indicating a co-occurring intellectual disability.
The prevalence of ASD has increased significantly since the late 1960s by about ** to ** times. Many studies suggest that this is due to improved awareness and recognition, as well as diagnostic capabilities. Autism is likely caused by a combination of genetics and environmental factors, where people with ASD may have abnormal levels of brain serotonin, which could disrupt early brain development.
