Yes, hyposensitivity and sensory seeking are officially recognised as part of the diagnostic criteria and autism sensory profile. Since the release of the DSM-5, sensory-related behaviours have been included as one of the four examples under the domain of restricted, repetitive behaviours. This shift acknowledged the importance of sensory processing challenges in understanding and assessing autism.
During an assessment, clinicians look for signs such as unusual responses to sound, texture, movement, or light. These might include both under-responsiveness (such as not noticing pain) and sensory seeking actions (such as craving movement or pressure). Including these sensory traits helps create a more accurate picture of how an autistic individual navigates the world and aligns with the broader scope of the diagnostic criteria and autism sensory understanding.
What the DSM-5 Says
To clarify how this fits into the formal process, here’s what you should know:
Sensory behaviours are now a core part of diagnosis
The DSM-5 includes “hyper- or hyporeactivity to sensory input or unusual interest in sensory aspects of the environment” as a diagnostic feature. This means clinicians must consider sensory patterns when evaluating for autism, especially in relation to the diagnostic criteria and autism sensory markers.
Observation and parent input are essential
Assessment tools often include direct observation and structured interviews with parents or caregivers. These help identify both hyposensitivity and sensory seeking behaviours across different environments.
Each profile is unique
Not every autistic person will show obvious sensory traits but recognising them improves diagnostic accuracy and guides better support planning.
