The eyes might disclose everything when it comes to ADHD and ASD. It's often said that “the eyes tell it all.” According to a recent study from Flinders University and the University of South Australia, regardless of their outward expression, the eyes may be able to signal neurodevelopmental problems like ASD and ADHD.
Eye tracking as a biomarker:
Eye tracking is especially useful for autism research because it can be used on young infants and children. This might allow researchers to develop biomarkers to diagnose autism at a young age, when early interventions are the most beneficial.
The behaviors that are attributable to both autism and vision problems can include lack of eye contact, staring at spinning objects or light, fleeting peripheral glances, side viewing, and difficulty attending visually. Autistic people may also have problems coordinating their central and peripheral vision.
The study found that children with autism have an unusually broad upper face, including wide-set eyes. They also have a shorter middle region of the face, including the cheeks and nose. Children with autism have a broader or wider mouth and philtrum - the groove below the nose, above the top lip.
Visual stimming is one of the self-stimulatory behaviours that children with autism often present with. It may include repetitive behaviours such as: Staring or gazing at objects, such as ceiling fans or lights. Repetitive blinking or turning lights on and off. Moving fingers in front of the eyes.
Autistic people often prefer to view inanimate objects over people interacting. This atypical gaze pattern may help clinicians flag autism before other traits appear. The average age of diagnosis in the United States is 4 years.

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.
People with autism sometimes may have physical symptoms, including digestive problems such as constipation and sleep problems. Children may have poor coordination of the large muscles used for running and climbing, or the smaller muscles of the hand. About a third of people with autism also have seizures.
Appear disinterested or unaware of those around them. Not know how to connect with others, seek out play, or make friends, or how to establish or maintain age-appropriate relationships. Not show enthusiasm/enjoyment during interactions or do not display shared enjoyment. Display aggression toward others.
Children on the autism spectrum typically have a number of similar behaviors that could be associated with a vision issue. Children with ASD may: Widen their eyes, squint or close an eye when asked to look. Stare intently at certain objects or patterns.
Main signs of autism
finding it hard to understand what others are thinking or feeling. getting very anxious about social situations. finding it hard to make friends or preferring to be on your own. seeming blunt, rude or not interested in others without meaning to.
Diagnosing autism spectrum disorder (ASD) can be difficult because there is no medical test, like a blood test, to diagnose the disorder. Doctors look at the child's developmental history and behavior to make a diagnosis. ASD can sometimes be detected at 18 months of age or younger.
The Autism Diagnostic Observation Schedule™ (ADOS™-2) is a standardized assessment of communication, social interaction, play, and restricted and repetitive behaviors in children. During an ADOS™-2 assessment, a specialist interacts directly with the child in social and play activities.
More than 15 percent of patients with autism or autism-related disorders exhibited strabismus, a type of eye movement disorder in which the eyes do not align properly; exotropia, or an outward turning of one or both eyes, was the most common form of strabismus seen.
Does The Father Or Mother Carry The Autism Gene? Autism was always thought to have a maternal inheritance component, however, research suggests that the rarer variants associated with the disorder are usually inherited from the father.
Defining the Traits and Behaviors of Level 1 Autism
Difficulty switching between activities. Problems with executive functioning which hinder independence. Atypical response to others in social situations. Difficulty initiating social interactions and maintaining reciprocity in social interaction.
It is possible to be mildly autistic, but many of the behaviors and preferences found in people with autism are also common to people who do not have autism. The difference is that people with autism engage in these behaviors in different ways and for different reasons.
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.
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.)
When a child or teen with autism is stared at, it's usually because s/he is displaying some type of social behavior that deviates from what society thinks of as normal. Usually, a person with autism does not appear different from others. (Although wearing headphones for noise reduction can attract attention).
Stimming behaviour is almost always present in people on the autism spectrum but does not, on its own, necessarily indicate the diagnosis. The biggest difference between autistic and non-autistic stimming is the type of stim and the quantity of stimming.
Excessive blinking is often accompanied by other tics and repetitive behaviors in children with autism. These behaviors can be categorized into two types: motor tics and vocal tics.
