What is the average age of autism diagnosis

A developmental screen is a short test using a validated screening tool to tell if a child is learning basic skills, and it can help determine if there might be a delay. This evaluation can include clinical observation, parental reports of developmental and health histories, psychological testing, and speech and language assessments.

A comprehensive developmental evaluation is often a key step in getting services, including through the school system. Diagnosis occurs when a developmental pediatrician, a child neurologist, a child psychiatrist, or a child psychologist uses the results of the comprehensive evaluation to determine if a child has ASD. Neurological and genetic testing can rule out other disorders and can check for genetic or neurological problems that sometimes occur along with ASD.

In addition, delays of more than two years between when parents first discuss concerns with a provider and receiving an autism diagnosis were associated with higher use of complementary and alternative medicine, which is considered more controversial. The strongest evidence for effective treatment for autism is for behavioral intervention therapy directed at core autism symptoms, such as social skills and inflexible behaviors. Other therapies, including complementary and alternative medicine and medication treatments for autism, are more controversial and are not as strongly supported by scientific studies.

Researchers, led by Katharine Zuckerman, M. They evaluated the children at least once more from age 5 to 9. Of the children, 99 were diagnosed with autism at age 3 and were diagnosed with related conditions.

However, another 14 children, including 1 from the control group, received an autism diagnosis after age 5. The team used a statistical model to search for patterns in the age 3 assessments that might herald a late diagnosis. When the team analyzed the data at both time points, a different set of patterns emerged.

Half of the late-diagnosed children scored well below the cutoff for an autism diagnosis at age 3, but their scores increased significantly at ages 5 to 9.

The other half scored just below the autism cutoff at age 3, and their scores bumped up slightly in that time.
