A reviewed-by-paediatrician guide to sensory processing differences for parents — what the patterns are, why this isn't a formal DSM-5 diagnosis but is widely recognised clinically, and what occupational-therapy-based intervention does well.
Sensory processing is the brain’s job of taking the constant stream of input from the world — sound, touch, taste, smell, sight, body-position information from joints and muscles, gravity-and-movement information from the inner ear — and prioritising what to attend to. For most adults, this happens silently and effortlessly. For roughly 5–16% of children, depending on the population studied, sensory processing is meaningfully different, and the difference shows up as a pattern of how the child responds to ordinary daily input.
Sensory processing differences usually fall into one (or a combination) of three patterns. Over-responsive children find common sensory input intensely uncomfortable: the seam in a sock is unbearable, the hum of an air-conditioner is exhausting, the texture of a banana is unmanageable. Under-responsive children seem indifferent to input that would alert most children — they may not notice when called, may not register temperature extremes well, may seem under-aroused much of the time. Sensation-seekers actively seek intense input: bumping into walls, pressing into furniture, mouthing objects past the developmental age, demanding rough physical play.
A given child rarely fits cleanly into one pattern. More often, the profile is mixed — over-responsive in some sensory systems, under-responsive in others, sensation-seeking in still others. The Sensory Profile-2 maps this systematically across systems.
Sensory processing disorder as a standalone diagnosis is not in the DSM-5-TR. The reasoning, articulated in the AAP’s 2012 policy statement and in subsequent debate, is that the field has not yet settled on whether sensory differences constitute their own distinct condition or are a feature commonly co-occurring within other recognised conditions (autism, ADHD, dyspraxia, anxiety). The clinical practice — assessing sensory processing and intervening with sensory-integration informed approaches — is well-established and widely accessed; what is contested is whether SPD should be carved out as its own diagnostic category.
In practice this means: occupational therapists routinely treat sensory processing patterns. Insurers and school systems may or may not accept SPD as a standalone diagnostic basis for accommodations. We help families navigate both questions during assessment.
The most widely-used framework for sensory work is Ayres’ Sensory Integration (ASI), developed in the 1970s and refined since. The approach combines specific input the nervous system needs (proprioceptive deep pressure, vestibular movement, oral-motor work) with structured opportunities for the child to self-organise their response. A “sensory diet” — a metaphor borrowed from nutrition — is a structured daily menu of regulating activities embedded in the child’s routine.
Crucially, the OT plan is built around the child’s specific sensory profile and the actual daily life of the family. A child whose primary challenge is over-responsiveness to clothing seams gets a plan that addresses clothing-tolerance work upstream of the morning meltdown. A child whose primary challenge is regulation during school transitions gets a plan that builds in regulating input at predictable points across the day. Generic “sensory activities” don’t replace this — the targeting is what produces change.
Sensory processing differences alone are clinically meaningful and treatable. But because they so often co-occur with broader developmental conditions, a careful initial assessment looks for autism markers, ADHD markers, dyspraxia, anxiety, and developmental language differences alongside the sensory profile. Where a broader picture is present, the OT plan integrates with the broader developmental plan rather than running in isolation. Where sensory differences are clearly the standalone concern, the OT plan stands on its own.
Lists like this are starting points, not diagnostic checklists. Many children show some of these signs and do not have sensory processing; some children with sensory processing present differently from anything described here. The right next step is a structured assessment, not a self-diagnosis.
The most widely used standardised parent-report assessment of sensory processing in children. Available in age-banded forms (infant, toddler, child, school-age). Maps the child's profile across sensory systems and produces a quadrant-based pattern (e.g., sensory sensitivity, sensory avoiding, low registration, sensation seeking).
A comprehensive clinician-administered battery for children 4–8 years assessing sensory integration and praxis. Used in research and complex clinical cases more than routine screening.
Direct OT observation of the child in their actual environment (often in their home, online or with the OT physically present) is essential alongside standardised tools. Many sensory patterns only become evident in real-world contexts — at meal-times, during transitions, in unfamiliar environments.
None of these alone is diagnostic. Together, particularly when persistent, they're the signals our paediatrician will want to evaluate.
OT remains the primary intervention. Approaches include Ayres' Sensory Integration framework, sensory diet planning (a structured menu of regulating activities embedded in the daily routine), and environmental adaptations.
Occupational Therapy programmeSensory regulation works best when delivered into the family's actual day rather than as separate appointments. The OT coaches parents on which routines to adjust, which sensory inputs to add, and which to scale back.
Occupational Therapy programmeSensory processing differences frequently co-occur with autism, ADHD, and dyspraxia. Where co-occurrence is present, the OT plan integrates with the broader developmental plan — autism programme, ADHD programme, or special education — rather than running in isolation.
Autism Programme programmeIt's a real, clinically recognised pattern — and it is not, currently, a standalone diagnosis in the DSM-5-TR. The American Academy of Pediatrics in its 2012 policy statement noted that sensory processing differences are commonly seen in children with autism, ADHD, and other developmental conditions, but recommended caution about treating SPD as a standalone diagnostic entity. In clinical practice, occupational therapists routinely assess and treat sensory processing patterns whether or not they meet a separate diagnostic threshold. The intervention exists; the formal diagnostic label is what's debated.
No. Sensory processing differences occur on their own in many children, and they also occur as part of the broader picture in autism, ADHD, dyspraxia, anxiety, and other developmental conditions. A skilled assessment maps the full profile — sometimes the answer is 'this child has sensory differences and nothing else'; sometimes the sensory differences are the surface presentation of a broader picture. Either answer leads to a useful plan.
A sensory diet is a structured menu of regulating activities — proprioceptive input (deep pressure, weight-bearing), vestibular input (movement, swinging), oral-motor input — embedded in the child's day at predictable times. The metaphor is nutrition: the child's nervous system has specific input it needs in regular doses to self-regulate well. The OT designs the diet around the child's specific profile.
Yes, with the parent as the in-room delivery agent. The OT designs the sensory diet, coaches the parent in real time on the techniques, and adjusts week by week based on what's working at home. Most of what an OT does for a sensory-regulation plan is assessment, planning, and coaching — all of which translate well to online delivery.
Most families notice meaningful changes in transitions, sleep, and overall regulation within the first 4–8 weeks of structured intervention. Targeted goals (specific feeding aversions, school regulation) typically take 3–6 months. Where sensory differences are part of a broader developmental picture, the sensory work continues alongside other modalities for as long as needed.
