Autism sensory differences diagnosis is an important aspect of the clinical assessment for autism, though sensory processing issues are not always explicitly included in formal diagnostic criteria. According to the DSM-5, which outlines the criteria for diagnosing autism spectrum disorder (ASD), sensory processing differences are recognised as a key feature of the condition, but they are grouped under broader behavioural patterns rather than being a standalone diagnostic criterion.

While the DSM-5 does not specifically list sensory processing differences as a primary diagnostic factor, sensory issues are described as part of the restricted, repetitive behaviours and interests that characterise ASD. These can include sensory sensitivities to light, sound, texture, or other sensory stimuli, which are often present in those with autism.

Sensory Issues in the Clinical Assessment of Autism

Here is how sensory processing differences are considered in the clinical assessment for autism:

Sensory sensitivities as a symptom

The DSM-5 includes sensory behaviours under the category of restricted and repetitive behaviours, noting that many autistic individuals show an unusual sensitivity or response to sensory input.

Assessment tools

Clinicians may use specific questionnaires or interviews to assess sensory issues, alongside other behavioural observations, when determining a diagnosis. Sensory challenges are often part of the overall picture but not always the primary focus in the diagnostic process.

Importance of comprehensive evaluation

Since sensory processing issues can vary widely among individuals, a thorough clinical assessment often includes considering sensory experiences to get a complete understanding of the individual’s needs.
