Yes, hypersensitivity in autism diagnosis is officially recognised as a core feature. It appears as part of the diagnostic criteria used by clinicians to assess whether someone is on the autism spectrum. Sensory responses, including heightened sensitivity to sounds, lights, or textures, are now considered clinically significant when determining a diagnosis.

This change came with updates to major diagnostic guidelines, which now include sensory symptoms as one of the key behavioural domains to consider. For many autistic individuals, these sensory challenges are just as impactful as social or communication differences. They may avoid certain environments, struggle with clothing or food textures, or find it difficult to cope in spaces with unpredictable sensory input.

How sensory symptoms factor into diagnosis

When clinicians assess for autism, they consider how sensory experiences affect daily life. Here are two main ways hypersensitivity in autism diagnosis is evaluated:

Behavioural Observations

Doctors and psychologists often observe reactions to sound, light or touch during assessments. Covering ears, flinching at light, or refusing certain fabrics can all point to sensory symptoms that support a diagnosis.

Parent and Self-Reports

Detailed information from parents, carers or the individual themselves is key. They might describe situations where loud environments cause distress or how certain clothes feel unbearable. These reports provide insight into patterns that match autism-related sensory symptoms.

Understanding the role of hypersensitivity in autism diagnosis helps ensure that sensory challenges are taken seriously and not overlooked.
