The early signs of autism can be detected in babies as young as six months, according to a new study by researchers at the University of North Carolina.

As part of the study, 92 infants underwent a special type of MRI called diffusion tension imaging. Researchers say the scans suggest autism doesn't appear abruptly, but instead develops over time during infancy.

The study's authors caution the findings do not mean that autism can be diagnosed with brain scans, but the research can help with earlier treatment.

The study can be found in the American Journal of Psychiatry.
