INDIANAPOLIS — One in 31 American children has been diagnosed with autism spectrum disorders,
three times higher than in the early 2000s
. Diagnostic criteria have broadened significantly over time, likely contributing to this rise, though unlikely to be the sole reason for the increase.
WISH-TV medical expert Dr. Janel Gordon
shares the basics, debunks a few myths, and shares some advice for parents.
A
neurodevelopmental condition
characterized by persistent social communication challenges, restricted interests, and repetitive behaviors.
Twin studies have shown
that 60-90% of autism could be hereditary, with genetics playing a role. To date, there has been insufficient information regarding possible environmental factors, and additional research is needed.
This idea persists from a debunked study from the 1990s reporting that eight children who received the MMR vaccine later developed autism. The findings were retracted, and
several studies have shown no association
.
Additional studies looked into the vaccine preservative, Thimerosal, and showed no association with autism. Studies have also looked at the number of vaccines given to a child at one time and found no association with autism.
Prevalence is higher among Asian, Black, and Hispanic children. Boys are over three times more likely to be diagnosed. Reasons for these disparities have not yet been identified, and more research is needed. Despite the risks, it is estimated that one-third of individuals with autism can navigate life with minimal to no assistance.
Keep a record of the symptoms and signs and speak to your child’s doctor about your concerns. Reach out to your local health department if your child does not have a doctor. Get a second opinion if needed.
Routine screening should take place between 18-24 months of age and is typically performed during the well-child visit. If symptoms become noticeable after this time, please do not hesitate to seek evaluation.
