What Causes Sensory Processing Differences in Autism? 

Author: Hannah Smith, MSc | Reviewed by: Dr. Rebecca Fernandez, MBBS

Causes of sensory processing in autism are rooted in how the brain processes and responds to sensory input. For autistic individuals, sensory experiences, such as light, sound, touch, and movement, are often perceived differently, leading to heightened or diminished responses. These differences are not a flaw but a result of the brain’s unique wiring. 

The neurological basis for these sensory differences lies in the way the brain’s sensory pathways and networks are structured. Autistic individuals may process sensory stimuli more intensely or less intensely than others, contributing to the wide range of sensory sensitivities observed in the autism spectrum. 

How the Brain Processes Sensory Information 

Here is how the causes of sensory processing in autism influence daily experiences: 

Neurological differences  

The brain of an autistic person may have differences in how it processes sensory signals, leading to either sensory sensitivity (overreacting to stimuli) or sensory under-sensitivity (seeking out or not reacting enough to stimuli). 

Imbalance in sensory integration  

Autistic individuals often experience difficulty in integrating and responding to multiple sensory signals at once, which can result in sensory overload or under-stimulation. 

Genetic and environmental factors  

Both genetics and environmental influences, such as early childhood experiences, may play a role in shaping these sensory differences, although the exact cause remains a topic of ongoing research. 

Understanding the causes of sensory processing in autism is crucial for developing effective strategies and creating environments that accommodate these unique sensory experiences.
