Autism facial features
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 Autism 1. Specifically, boys with autism have broader faces and mouths, flatter noses, narrower cheeks and a shorter philtrum — the cleft between the lips and nose — compared with controls, according to the three-dimensional facial imaging system used in the study. These distinctive features suggest that certain embryonic processes that give rise to facial features are perturbed during development, the researchers say. The participants in the study were all 8 to 12 years old, an age range during which the face is relatively mature, but not yet affected by the hormonal changes of puberty.
Is it autism? Facial features that show disorder
Autistic facial characteristics identified -- ScienceDaily
Childhood autism is a neurodevelopmental disorder characterized by impairments in social interactions, verbal and non-verbal communication and by a pattern of stereotypical behaviors and interests. The aim of this study was to estimate the dysmorphic facial features of children with autism and children with Asperger syndrome. The examination was conducted on 60 children 30 with childhood autism and 30 with Asperger syndrome. The photo anthropometric method used in this study followed the protocol established by Stengel-Rutkowski et al. The performed statistical analysis showed that in patients with childhood autism, the anteriorly rotated ears and the long back of the nose appeared more often. In the group of children with autism, there was a connection between the amount of dysmorphies and the presence of some somatic diseases in the first-degree relatives.
Facial features provide clue to autism severity
The face and brain develop in coordination, with each influencing the other, beginning in the embryo and continuing through adolescence. Now, University of Missouri researchers have found distinct differences between the facial characteristics of children with autism compared to those of typically developing children. This knowledge could help researchers understand the origins of autism. Knowing that point in time could lead us to identify a genetic cause, a window of time when the embryo may be susceptible to an environmental factor, or both. Aldridge and colleagues found the following distinct differences between facial characteristics of children with autism and those of typically developing children:.
Facial expressions smooth social interactions: A smile may show interest, a frown empathy. People with autism have difficulty making appropriate facial expressions at the right times, according to an analysis of 39 studies 1. Instead, they may remain expressionless or produce looks that are difficult to interpret.
