Definition
Sensory Processing Disorder describes difficulty taking in, organising, and responding to everyday sensory information (touch, sound, movement, taste, smell, sight, balance, and body awareness) in a way that supports daily life. SPD is not in ICD-11 or DSM-5 as a stand-alone diagnosis but is widely used in UK paediatric OT practice.
In context for parents
Key checkpoints
- SPD describes difficulty taking in, organising, and responding to everyday sensory information.
- Not a stand-alone diagnosis in ICD-11 or DSM-5; widely used in UK paediatric OT practice.
- UK clinical framework is Winnie Dunn's four quadrants (low registration, sensation seeking, sensory sensitivity, sensation avoiding), assessed via the Sensory Profile-2.
- A personalised sensory diet plus environmental adjustments (ear defenders, dining hall management, movement breaks) are the typical interventions.
- SPD alone does not cross the EHC threshold; cases that do tend to involve EBSA, severe meltdowns, or feeding difficulty.
The framework most UK paediatric OTs work from is Winnie Dunn's four-quadrant model (low registration, sensation seeking, sensory sensitivity, sensation avoiding), assessed via the Sensory Profile-2. Some clinicians, especially those with the Ayres Sensory Integration certification (SI Network UK and Ireland), use the Sensory Integration and Praxis Tests. The diagnosis is descriptive: it tells you which sensory systems are mis-registering input, not why.
In a Year 1 classroom, SPD might be the child who melts down at the dining hall because the noise of 80 cutlery sets on plates is physically painful, not because they are difficult. At home it is the child who can only wear one pair of leggings because every other texture is intolerable, or the child who needs to crash into the sofa for 20 minutes after school to put their proprioceptive system back together. These are not preferences; they are nervous system regulation.
What helps: a personalised sensory diet (planned, scheduled activities: heavy work, deep pressure, oral input, vestibular movement) and environmental adjustments at school. The big ones: ear defenders in the dining hall, a seat near the window not the strip-lighting, a movement break between lessons rather than after a meltdown, and a "safe space" agreed in advance.
SPD on its own does not meet the threshold for an EHC needs assessment. The cases that do are those where sensory needs drive EBSA, meltdowns, or feeding difficulties severe enough that mainstream provision without specialist OT input would not work, and OT provision can then be quantified in Section F.
Related terms
The terms parents most often see alongside Sensory Processing Disorder.
Sensory Diet
A planned, individualised programme of sensory activities scheduled across the day to help a child stay regulated. Usually devised by an occupational therapist.
Sensory Integration
A clinical approach developed by occupational therapists that helps the brain organise sensory input through specific, often play-based, therapeutic activities.
Interoception
The internal sense that tells us what is happening inside the body: hunger, thirst, needing the toilet, heart rate, emotion. Differences in interoception are common in autism and ADHD.
Occupational Therapist(OT)
An HCPC-registered specialist who supports children to participate in everyday activities, working on fine motor skills, sensory processing, self-care, and handwriting.
Sensory Overload
A state where one or more senses receive more input than the brain can process, leading to distress, meltdown, or shutdown. Common triggers include noise, fluorescent lighting, crowds, and unexpected touch.
Where parents ask about this
Parents usually find this page after a school has labelled a sensory meltdown as a "behaviour incident", after a long wait for community OT, or in the run-up to an annual review where they want sensory provision properly written into Section F. Searches include "private sensory assessment UK", "school sensory diet", and "sensory provision Section F EHCP". A Beaakon paediatric OT can carry out a Sensory Profile-2, write a sensory diet the school will actually follow, and quantify the OT input needed for SEN Support or Section F.
