Sensory Issues in Autism

Sensory issues are common in children with autism. You might often catch them fidgeting, running around, or touching everything they see. Other times, they might appear uninterested or even avoidant of their surroundings.

Every child with autism is unique and will experience the world differently. The key to providing the right kind of support involves understanding what triggers these sensory issues and what doesn’t. This article will discuss the common sensory issues in children with autism and what kind of therapy may be appropriate for your child.

Sensory Issues in Autism

Sensory issues in autism are a result of differences in how the brain receives and interprets information. Normally, the brain receives signals through sensory receptors and relays them through various neural pathways. Autism may change this sensory experience because of how the brain alters these circuits and pathways [*].

Simply put, the autistic brain is wired differently. For example, when a neurotypical child has a conversation with a friend, they might automatically drown out background noise. For a child with autism, all sounds compete at a similar volume, even if they aren’t pertinent to the discussion.

Here are a few common sensory issues autistic children may experience differently:

• Pain: Autistic children may feel pain more intensely or appear not to be affected at all. They may have low body awareness.
• Smell: Sometimes, children with autism may find certain smells extremely unpleasant or find that they really enjoy smelling certain things.
• Sight: Some kids with autism may find themselves staring at certain visual stimulants (such as flashing lights or falling leaves) for a long time or become overwhelmed by certain sights.
• Touch: Many children with autism find textures and physical contact very uncomfortable. They may struggle to cope with touching certain things because of how it makes them feel.
• Hearing: Children with autism may find that certain noises bother them, even if they don’t typically bother other people.

Not every person with autism has sensory issues. According to recent studies, between 60% to 96% of children experience sensory symptoms [*]. Sensory issues aren’t exclusive to autism either, as people diagnosed with ADHD or anxiety can also experience them.

Hypersensitivity vs. Hyposensitivity: Two Different Experiences

Autism sensory issues can manifest as hypersensitivity (being over-responsive) and hyposensitivity (being under-responsive). In many cases, children with autism experience both.

When autistic children are hypersensitive, their environment may feel too fast, strong, or intense. They might feel apprehensive towards certain triggers or have meltdowns. Conversely, autistic children with hyposensitivities may not be as reactive to stimulants and appear aloof.

What Sensory Issues Look Like

Often, an autistic child’s sensory issues are highly visible. Here’s what you might observe:

• Sensory avoidance: Hyper-reactive children may quickly become physically overwhelmed when they can’t adjust to their environment. If the trigger is a noise, they might cover their ears. If they have tactile issues, they might try removing tags from their clothes or refuse to get a haircut.
• Sensory seeking: For children who are hypo-reactive, they might manifest their sensory issues by seeking out intense physical experiences. These experiences might include roughhousing, running around, touching everything they see, or putting things in their mouths. They might engage in something called stimming, which looks like constant fidgeting and restlessness.
• Behavioral shutdowns: When a child is overstimulated, their mind and body will react in a way that protects them. In some cases, this may look like a behavioral shutdown. The child might withdraw socially, refuse to talk, or self-isolate to create space between themselves and their environment.
• Behavioral meltdowns: Occasionally, a child who doesn’t experience shutdowns may have a meltdown instead. They might scream, cry, kick, and thrash as a response to being overstimulated.

What Sensory Issues Feel Like

Children with autism aren’t being picky or overly sensitive. In some cases, sensory issues feel like an assault on the body. For example, in a classroom setting, hearing the teacher talk, cars passing by outside, and their classmates participating can feel like being trapped in a small room with several televisions on at full blast.

If your child has tactile sensitivities, something as simple as touching a microfiber towel can feel like they’re running their hands over a sheet of sandpaper. Certain sights can feel equally as intrusive. Fluorescent lights may be too bright, and visual clutter might feel “loud.”

Another issue the autistic brain struggles with is predictive processing (sometimes called predictive coding). This issue makes it difficult for children with autism to expect what something feels like, even if they’ve experienced it before.

Coping Strategies for Sensory Issues

Helping a child with sensory issues doesn’t mean eliminating the sensitivities themselves. Instead, it involves empowering them to regulate their responses. The approach will differ depending on whether you’re dealing with hyposensitivity or hypersensitivity.

Here’s what you can do for children with hypersensitivities:

• Make small environmental modifications at home: While you won’t have control over the outside environment, you can make your home a little more comfortable for your child. Decorate sparingly so they aren’t visually overstimulated. You can also create a quiet space in various areas of the home, such as their room or the living area. This quiet space might have a weighted blanket or small tent to keep their environment “outside” for a short moment. Buy clothes that your child is comfortable wearing and cut off tags as necessary.
• Create structure: Children with autism lack the concept of predictability. No matter how many times they’ve experienced something in the past, it will be just as scary or uncomfortable as the first time they experienced it, especially when they lack regulation skills. Creating a clear, visual schedule or integrating sensory breaks throughout the day can help them cope with their environment more effectively.

Children with hyposensitivities may require different accommodations. These include the following:

• Introduce balanced movement: Hyposensitive children often under-register their surroundings and require deliberate movement. Provide daily intervals for balanced movements through play or exercise, such as spending time outdoors or trying yoga.
• Provide sensory outlets: Sometimes, a hyposensitive child will do more to feel more. You can provide safe outlets, such as medical-grade silicone chews or sensory bins filled with materials like rice or kinetic sand. Ensure the stim toys you provide are appropriate for your child's age.
• Incorporate deep pressure: Resistance exercises and heavy work can stimulate the joints in ways that hyposensitive children don’t usually experience. Helpful items like weighted blankets or exercises like pushing something heavy (such as a full laundry basket) can create calming, deep-pressure effects.

Can Sensory Issues in Autism Be Improved?

Yes, it’s possible to improve sensory issues in children with autism with the right therapeutic support. The effectiveness of treatment varies from child to child and depends on their individual needs. They may include:

• Occupational therapy with Ayres Sensory Integration: This play-based intervention takes the child’s lead as therapists offer safe “challenges.” These challenges include simple physical activities, such as using weighted items, playing on a swing, or tossing a ball. OT-ASI aims to increase body awareness and gradually reduce hypo- and hyper-sensitivity during mundane tasks, such as helping with the chores or sitting through a class [*].
• Environmental modification strategies: Creating a safe environment at home matters as much as clinical therapy. Employ simple modifications, such as switching out strong fluorescent lighting with dimmer LEDs or dampening sound with acoustic panels, to keep unexpected sensory transitions at a minimum.
• Feeding-focused multidisciplinary care: If your child has severe food selectivity, occupational therapists take a Sequential Oral Sensory (SOS) approach to increase a child’s tolerance to certain tastes, smells, and textures [*]. They take small steps to introduce new foods to the child with no pressure to taste or even try them.
• Cognitive-behavioral therapy (CBT): Mindfulness-focused cognitive-behavioral therapy activities can help children with hyper-sensitivity manage their anxiety and distress over specific triggers.

The Bottom Line

While sensory issues are common in children with autism, no two kids experience the same thing. Some kids may become quickly overstimulated, while others may require lots of activity to feel excited and fulfilled. The important thing is finding ways to make your child’s environment a safe one for their exploration.
