Researchers at Canada’s McMaster University have developed computerized tests using eye-movement sensors to predict the risk of autism in children as young as 9 months old – almost two years earlier than specialists generally start spotting signs of the disorder.
Yale University's Toddler Developmental Disabilities Clinic is using similar eye-tracking technology to study patterns in gaze behavior in children ages 3 months to 3 years. And the Massachusetts Institute of Technology's Media Lab is developing software and an in-home recording device to analyze the habits of newborns, looking for subtle signs of early autism.
Autism specialists say such new technologies can provide useful clues, but that a proper diagnosis requires human observation to consider various possible symptoms.
