Autism Screenings Missing Some Children
Your Health Minute
In Your Health News,
Researchers in Norway followed more than 69 thousand 18 months olds who tested negative for autism.
They found several differences in behavior between children who were later diagnosed with the disorder and those who were not.
Autistic children tended to have delays in social interaction, communication and motor skills.
Those with milder or more infrequent symptoms were less likely to be diagnosed early.
