Chapter Eighteen: Sensory Overload - A Stimulus-Rich World

Children with sensory processing differences experience overwhelming environments as distressing and exhausting, requiring understanding, tailored support, and practical accommodations to help them thrive

Chapter Eighteen Summary

Chapter 18, “Sensory Overload: A Stimulus-Rich World,” explores how children—especially those who are neurodiverse—experience and cope with overwhelming sensory input in daily life. The chapter opens with the story of Q, a student whose heightened sensitivity to sounds, lights, and textures leads to distress, headaches, and emotional meltdowns at school and home. Q’s experiences illustrate how ordinary environments can feel chaotic and painful for children with sensory processing differences, often resulting in behaviors misinterpreted as defiance or tantrums.The chapter outlines three main dimensions of intelligence—conceptual, mechanical, and behavioral—and contrasts these with the three pillars of adaptive skills: conceptual (planning, organization), practical (self-care, safety), and social (relationship building, emotional regulation).

The chapter explains that sensory overload occurs when the brain cannot efficiently filter and process excessive sensory information, triggering emotional, cognitive, and physical responses like anxiety, irritability, and shutdowns. These challenges are particularly common in children with autism, ADHD, FASD, or trauma histories, but can also affect neurotypical children. Symptoms include meltdowns, tactile sensitivity to clothing, and difficulty focusing or following directions.

Caregivers are encouraged to advocate for accommodations—such as noise-canceling headphones and modified classroom environments—and to provide access to calming outdoor spaces. The chapter emphasizes the importance of understanding the neurological basis of sensory overload, highlighting the roles of the thalamus and prefrontal cortex in filtering sensory input and regulating responses. It offers practical strategies for supporting children, including clear communication, environmental adjustments, and collaboration with professionals.

Key Takeaways for Parents/Caregivers

Physical Responses not Misbehavior

Sensory overload occurs when the brain struggles to process excessive sensory input—such as loud noises, bright lights, crowded spaces, or uncomfortable textures—leading to emotional, cognitive, and physical responses that may be mistaken for misbehavior

All Children can be Impacted

Children with neurodevelopmental differences (autism, ADHD, FASD, trauma histories) are especially prone to sensory overload, but neurotypical children can also experience it

Common Symptoms

Common symptoms of sensory overload include meltdowns, emotional outbursts, shutting down, and increased anxiety in crowded or noisy environments

Neurological Responses

Meltdowns are neurological responses, not intentional misbehavior or tantrums, and require calm, low-stimulus environments for recovery—not punishment

Tactile Sensitivity

Heightened tactile sensitivity is common, with children often distressed by certain fabrics, tags, or clothing seams, which can feel intensely uncomfortable to them

Focus Disruption

Sensory overload can disrupt focus and the ability to follow directions, as the brain prioritizes survival over attention and learning in overwhelming situations

Simple Communication/Visual Support

Clear, simple communication and visual supports (like charts or checklists) help children process instructions better during sensory stress

Sensory Limiting Accomodations

Advocating for accommodations—such as noise-canceling headphones or seating changes—can significantly improve a child’s participation and comfort in school and public settings

Document, Document and Collaborate

A sensory diary, medical documentation, and collaboration with professionals (e.g., occupational therapists) are valuable tools for effective advocacy

Brain Regions

The thalamus and prefrontal cortex play key roles in processing and filtering sensory information; dysfunction in these areas can lead to overload and difficulty with self-regulation

Brain Impact

Adaptive behavior and executive function are often affected, making transitions, organization, and emotional control more challenging for neurodiverse children

Compassion and Empathy

Compassionate understanding and environmental adjustments—not attempts to “fix” the child—are essential for helping children thrive in a stimulus-rich world
