WHat is Autism?
What is autism?
Autism spectrum disorder (ASD) encompasses a wide range of neurodevelopmental conditions marked by difficulties in social interaction, repetitive behaviors, and challenges with verbal and nonverbal communication. According to the Centers for Disease Control and Prevention (CDC), autism currently affects approximately 1 in 35 children and 1 in 45 adults in the United States.
Autism is a lifelong condition, and the strengths, needs, and challenges of autistic individuals can evolve over time. As they move through different stages of life, their required supports and accommodations may also change. Early intervention and tailored therapies can significantly improve skill development and long-term outcomes.
What causes autism?
Two main factors that influence autism are genetics and environment.
These factors seem to elevate the likelihood of developing autism and may influence the specific characteristics a child exhibits. However, it's important to remember that an increased risk does not equate to a direct cause. For instance, certain genetic variations linked to autism are also present in individuals without the condition. Likewise, many people exposed to environmental risk factors do not go on to develop autism—in fact, the majority do not.
Autism is a spectrum
Autism looks different for everyone, and each person with autism has a distinct set of strengths and challenges. Some autistic people can speak, while others are nonverbal or minimally verbal and communicate in other ways. Some have intellectual disabilities, while some do not. Some require significant support in their daily lives, while others need less support and, in some cases, live entirely independently.
Current diagnostic guidelines in the DSM-5-TR break down the ASD diagnosis into three levels, based on the amount of support a person might need: Level 1, Level 2, and Level 3.
Co-occuring conditions
Individuals diagnosed with autism can also exhibit accompanying conditions such as:
Gastrointestinal (GI) disorders
Seizures and sleep disorders
Attention-deficit/hyperactivity disorder (ADHD)
Anxiety and depression disorders

*NEW* Side eye glancing
Although there isn't concrete evidence to confirm the connection with this behavior to ASD, there have been many speculations that this could be a sign.
Side-eye glancing is defined as a quick, often discreet, sideways look at something or someone. In neurotypical individuals, this behavior can convey a range of emotions, such as skepticism, curiosity, or disapproval.
For those with autism, however, the interpretation of side-eye glances may differ significantly, often influenced by their unique experiences and sensory processing differences.
Contextual Interpretation of Side Eye Glances
The meaning attributed to side-eye glancing is highly contextual. Factors such as body language, facial expressions, and the specific social situation all contribute to the interpretation of this behavior. For instance, if an individual with autism gives a side-eye glance while in a crowded setting, it may indicate discomfort or a desire to observe their surroundings without engaging too intensely.
Conversely, a side-eye glance may also express curiosity or interest in what another person is doing or saying, albeit from a distance. Essentially, the complexity of this behavior highlights a broader truth about communication—meaning is rarely derived from a single action but rather shaped by multifaceted interactions and individual preferences.
Coping mechanism or social signal?
For many individuals on the spectrum, side-eye glancing can function as a coping mechanism in challenging social scenarios. The act of looking away might allow them to reduce sensory overload while still gathering necessary information about their environment.
In situations where direct eye contact could feel intrusive or overwhelming, side-eye glancing presents a less intense alternative, enabling them to stay connected without feeling threatened.
One must be cautious not to generalize this behavior as indicative of discomfort alone. The personal history and self-awareness of each individual will inform their use of eye movements, and side-eye glancing may sometimes signal a willingness to engage, albeit cautiously.
