A new study looks into the mysteries behind Autism Spectrum Disorder.
Researchers at UNC-Chapel Hill say a region of the brain responsible for processing faces and emotions is enlarged in young children with autism.
Researchers studied the brain abnormality through MRI brain scans of 2 and 4-year-olds. Doctors say this particular part of the brain plays a role in numerous functions, including how a person handles emotion.
The research is consistent with other studies that have linked autism with accelerated head circumference growth rates.
