Diagnosing autism spectrum disorder can be difficult because there is no medical test (like a blood test) to diagnose the disorder. Rather, psychologists evaluate the individual’s developmental history and behavior to make the diagnosis. At first glance, some people with autism may appear to have an intellectual disability, sensory processing issues, or problems with hearing or vision. Thorough diagnostic assessment by a trained psychologist is necessary for proper diagnosis. Also, early intervention is important, and if you are concerned about your child’s development, please refer to resources from the CDC, such as https://www.cdc.gov/ncbddd/actearly/pdf/FULL-LIST-CDC_LTSAE-Checklists2021_Eng_FNL2_508.pdf
