Sensory differences without autism are possible and can occur in a variety of contexts. While sensory processing(1*) issues are often associated with autism, they are not exclusive to it. People with other neurodivergent conditions, such as ADHD, sensory processing disorder (SPD), or even those without any formal diagnosis, can experience similar sensory issues.

Sensory processing differences refer to how individuals respond to sensory input, such as light, sound, texture, or smell. Some people may be overly sensitive (hyper-sensitive) to certain stimuli, while others may be under-sensitive (hypo-sensitive). These differences can lead to discomfort, stress, or difficulty with everyday tasks, and they can occur in both neurotypical and neurodivergent individuals.

Sensory Issues Outside of Autism

Here is a closer look at how sensory differences without autism can manifest in different contexts:

Sensory Processing Disorder (SPD)

SPD is a condition where the brain struggles to process sensory input appropriately. It can exist independently of autism and may present as heightened sensitivity or seeking out sensory experiences.

ADHD and sensory issues

Many individuals with ADHD also report experiencing sensory sensitivities or seeking behaviours. However, these issues may arise from different neurological causes compared to autism.

Other neurodivergent conditions

People with conditions like anxiety disorders, PTSD, or intellectual disabilities can also experience sensory issues that disrupt daily life, although they may not fit the autism diagnostic criteria.

Understanding that sensory differences without autism can exist broadens our understanding of how sensory processing affects various populations. It helps ensure that people with these differences receive the support they need, regardless of their specific diagnosis.
