Some of the frequent facial features of autism are a broader upper face, shorter middle face, wider eyes, bigger mouth, and the philtrum [19]. The use of facial features as a physical marker to detect autism is one of the most exciting topics in autism research.
In previous studies, children with autism have been found to have unusually wide faces and wide-set eyes. The cheeks and the nose are also shorter on their faces (Aldridge et al., 2011).
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 studies1. Instead, they may remain expressionless or produce looks that are difficult to interpret.
There is no one specific facial feature that is characteristic of autism. However, some studies have suggested that individuals with autism may have a broader forehead or wider-set eyes than neurotypical individuals.
Our findings suggest that individuals with autism are impaired in their ability to evaluate beauty, at least when beauty is associated with an objective parameter intrinsic to works of art (proportion in the case of classical representations).
Yes. A study by Washington State University shows autistic children had a different visual response to light. Their pupils reacted 16 milliseconds slower for low-level flashes and 40 milliseconds for brighter beams than their non-autistic peers. Eye-tracking technology can also help diagnose ASD in infants.
Myth 1 – autistic people cannot make eye contact
This is well known but factually inaccurate. Whilst many autistic people struggle to make eye contact, some are able to, so don't assume someone who identifies as being autistic won't be able to meet your gaze.
Siblings of autistic children, like those with the condition, tend to have faces that are more masculine than average, according to a new analysis1. The analysis classified features such as a wide forehead and long nose as masculine.
There are other brain disorders that mimic autism symptoms, like ADHD and anxiety disorders, including selective mutism. Autism can be misdiagnosed as another disorder with some shared symptoms.
Main signs of autism
finding it hard to make friends or preferring to be on your own. seeming blunt, rude or not interested in others without meaning to. finding it hard to say how you feel. taking things very literally – for example, you may not understand sarcasm or phrases like "break a leg"
Some children with autism smile to show they're happy but don't share their enjoyment. Others show little facial expression or have flat affect and rarely smile so you may not know when they're happy.
Facial expressions between autistic and typical people may be mismatched. Conversations between an autistic and a typical person involve less smiling and more mismatched facial expressions than do interactions between two typical people, a new study suggests1.
Smiling may not come easily to you if you are autistic or neurodiverse. It might feel unnatural or insincere. It doesn't mean you're in a bad mood if you don't smile. You could be neutral or really focused on your work.
Girls with autism tend to have smaller heads and bodies than their typically developing peers, whereas boys with the disorder tend to have average-sized heads and slightly larger bodies, report two studies published in July.
UNIVERSITY PARK, Pa. — The ability to recognize faces varies greatly, but individuals with autism spectrum disorders can especially struggle, having huge implications for social interaction.
It is a spectrum disorder, meaning there is a broad variation in the types and severity of symptoms. No two people with ASD have the same symptoms. Borderline autism is not an official term or diagnosis. Instead, it is an informal term referring to less severe ASD symptoms.
Although the exact cause of autism is still unknown, there is evidence to suggest that genetics play a significant role. Since autism is less prevalent in females, autism was always thought to be passed down from the mother. However, research suggests that autism genes are usually inherited from the father.
Asperger's syndrome.
This is on the milder end of the autism spectrum. A person with Asperger's may be very intelligent and able to handle their daily life. They may be really focused on topics that interest them and discuss them nonstop. But they have a much harder time socially.
As a group, children with ASDs appear to be taller than their unaffected siblings. Children with Asperger's Syndrome and Autism, specifically, appear taller than those with PDD-NOS who, in turn, do not differ from unaffected siblings in height. (See Figure 1.)
Therefore, it appears that while some individuals may be aware they are autistic, others may not fully understand why they have difficulties connecting with people socially or engaging in conversation - yet still realize they are 'different.
“Research suggests these girls may show more social interest. And any repetitive behaviors or restrictive interests may be less apparent. It can be more difficult to notice and for healthcare providers to diagnose.” For example, kids with autism tend to prefer to play alone, rather than engage in group activities.
A tendency to avoid eye contact is an early indicator of Autism Spectrum Disorder (ASD), and difficulties with eye contact often persist throughout the lifespan. Eye contact difficulties may underlie social cognitive deficits in ASD, and can create significant social and occupational barriers.
One theory is that the reason that eye contact is difficult for most but not all autistics is that alexithymia may mediate this experience. Research shows that irrespective of autism, alexithymia appears to play a role in avoidance of other people's eyes.
Summary: Individuals with autism spectrum disorder often find it difficult to look others in the eyes as they find eye contact uncomfortable or stressful.
