(WXYZ) - According to an ABC report, the first signs of autism may show up in the first month of a child's life.
Eye contact continues to decline in these babies up to two years of age. The findings – by researchers in Autism Speaks Baby Siblings Research Consortium – appeared Thursday in the journal Nature.
Researchers used eye tracking technology to study from birth to three years. They found that babies watched their mother's movement.
But, babies who were later diagnosed with autism followed their mom's eyes less, as early as one month old.
Parents shouldn't worry if an infant doesn't always meet their eyes, the researchers emphasize. The changes they documented with technology are not visible to the naked eye. Indeed, earlier studies without the eye-tracking technology failed to capture the pattern.
