The presence of any of three abnormal physical features — an asymmetrical face, tufts of hair growing in the wrong direction or a prominent forehead — can help diagnose autism, according to a study published 6 June in the Journal of Autism and Developmental Disorders1.
Which characteristic is most common to autism?
These are some of the characteristics of ASD:
- problems with social interaction with others.
- unusual interest in objects.
- need for sameness.
- great variation in abilities.
- under or over reaction to one or more of the five senses: sight, touch, taste, smell, or hearing.
- repeated actions or body movements.
What is the hallmark symptom of autism?
The hallmark feature of autism spectrum disorder (ASD) is impaired social interaction. A child’s primary caregivers are usually the first to notice signs of ASD. As early as infancy, a baby with ASD may be unresponsive to people or focus intently on one item to the exclusion of others for long periods.

What are the facial features of a boy with autism?
Face map: Boys with autism have broader faces and mouths, flatter noses and narrower cheeks than controls do. Boys with autism have a distinct facial structure that differs from that of typically developing controls, according to a study published 14 October in Molecular Autism1.
What is the autistic facial phenotype?
In all of these, the participants with autism appeared closer to what’s typically characterized as a male face. Other findings were in line with similar studies that have defined the autistic facial phenotype as an increased height and mouth width, and decreased midface height.
Is an asymmetrical face a sign of autism?
First, they classified children with an asymmetrical face as part of the autism group. When they compared this designation with the children’s true diagnoses, they found that only three percent of the controls meet this criterion.
Are hair whorls a sign of autism?
The researchers also placed children with abnormal hair whorls — multiple tufts of hair growing in the opposite direction from the rest — as well as children with a prominent forehead in the autism group. These three factors accurately identified 96 percent of the autism sample and misclassified 17 percent of controls.
