Exploring the causes of hyposensitivity in autism offers insight into why many autistic people show strong sensory seeking behaviours. These patterns are linked to how the brain interprets, or under-interprets, sensory information. Instead of processing signals at a typical level, the brain may register them faintly, leading individuals to seek out stronger stimulation.
Researchers point to several neurological factors behind this. Differences in how sensory pathways develop and connect may influence how information travels to and is processed by the brain. This explains why two autistic individuals can have very different sensory seeking responses, even if they share the same diagnosis.
The Role of Brain Processing
The causes of hyposensitivity in autism are often tied to differences in brain processing. Here’s how this plays out in practice:
Reduced sensory registration
Some autistic people may not register pain, temperature, or sound in the same way as others. Therapies often focus on increasing awareness and teaching safe responses.
Intense sensory seeking to compensate
Behaviours like spinning, jumping, or chewing help boost under-registered input. Occupational therapy can provide safe and structured ways to meet this need.
Variability across senses
One person might show hyposensitivity to sound but hypersensitivity to touch. This mix is part of the complexity of neurological factors in autism.
