Some children react to everyday sights, sounds, textures and movement in ways that make ordinary routines hard: a haircut ends in tears, socks have to be “just right,” or the child never seems to sit still. Many families call this sensory processing disorder (SPD). This guide explains how such difficulties are evaluated, which treatments exist, what the evidence says, and what parents can do at home and at school.
Key points
- Sensory processing disorder is not listed as a separate diagnosis in the DSM-5.
- Sensory differences are part of autism diagnostic criteria and often accompany ADHD, anxiety, and developmental delays.
- Clinicians describe three patterns: over‑responsivity, under‑responsivity, and sensory seeking.
- The AAP advised against using SPD as a stand‑alone diagnosis and recommends time‑limited trials with measurable goals.
- Evaluation includes pediatric review, vision and hearing checks, screening for related conditions, and an OT evaluation with written goals.
What “sensory processing difficulties” means
The term describes trouble noticing, interpreting or responding to sensory input: sound, touch, sight, taste, smell, movement and body position. Sensory processing disorder is not listed as a separate diagnosis in the DSM-5, the manual US clinicians use for mental and developmental conditions. Sensory differences are, however, part of the diagnostic criteria for autism spectrum disorder, and they often appear together with ADHD, anxiety and developmental delays.
Occupational therapists usually describe three patterns:
Over-responsivity
The child reacts strongly to ordinary input: covering ears at a hand dryer, refusing clothes with seams, panicking in a crowded store or during tooth brushing.
Under-responsivity
The child seems slow to notice input, may not respond when called, appears tired or passive, and may not notice scraped knees, cold or a runny nose.
Sensory seeking
The child looks for intense input: crashing into furniture, spinning, jumping for long periods, chewing on shirts or pencils.
What pediatricians recommend
In its 2012 policy statement on sensory integration therapies, the American Academy of Pediatrics (AAP) advised pediatricians not to use sensory processing disorder as a stand-alone diagnosis and noted that research on sensory-based therapies is limited and mixed. The AAP does not rule them out. It recommends that families and clinicians agree on a time-limited trial with clear, measurable goals and check whether those goals are met.
Evaluation comes first
- Pediatric visit. The pediatrician reviews development, sleep, feeding and behavior, and looks for medical causes.
- Vision and hearing checks. Poor hearing or uncorrected vision can look like a processing problem.
- Screening for related conditions. Autism, ADHD, anxiety and language disorders commonly come with sensory differences and change the treatment plan.
- Occupational therapy (OT) evaluation. A therapist experienced in sensory integration assesses the child.
A typical OT evaluation includes a parent or teacher questionnaire such as the Sensory Profile 2, standardized testing where appropriate (for example the Sensory Integration and Praxis Tests or the newer Evaluation in Ayres Sensory Integration), and observation of the child’s balance, motor planning and play. The result should be a written report with specific goals tied to daily life, such as getting dressed without a meltdown or staying at the dinner table for ten minutes.
Ayres Sensory Integration therapy
Ayres Sensory Integration (ASI) is the approach developed by occupational therapist A. Jean Ayres. It is play-based and child-led: the therapist sets up activities on swings, climbing structures, crash mats and ball pits, and adjusts the challenge so the child succeeds just beyond current skills. Sessions usually take place one to three times per week.
The strongest research support comes from studies with autistic children, where individually tailored ASI has shown gains on personal goals. For other groups the evidence is thinner. Progress is often tracked with Goal Attainment Scaling, which defines in advance what “expected,” “better than expected” and “less than expected” look like for each goal.
Questions worth asking the therapist:
- What exactly are the goals, and how will we measure them?
- How many sessions are planned before we review progress?
- What should we practice at home between sessions?
- What happens if the goals are not met?
The sensory diet
A “sensory diet” is a schedule of activities spread across the day that helps a child stay calm and alert. The therapist tailors it; common elements are:
- Heavy work: carrying grocery bags, pushing a laundry basket, wall push-ups, bear crawls and crab walks.
- Movement breaks: a few minutes of jumping, running or stretching every 20 to 60 minutes during homework or long tasks.
- A calm corner: a quiet spot with dim light, a beanbag, a heavy blanket for the lap, and headphones.
Everyday strategies by sense
Sound
- Noise-reducing headphones for vacuuming, fire drills, fireworks or busy stores.
- Advance warnings (“In five minutes the blender will be loud”) and visual timers.
Touch
- Tagless shirts, seamless socks and soft cotton; let the child test options.
- Firm, predictable touch instead of light, ticklish contact; ask before touching.
- New textures in small steps, with the child in control of the pace.
Food textures
- Offer a new food next to a familiar one; touching and smelling it counts as progress.
- Never force or punish; model calm eating. Very limited diets or weight loss need a pediatric check.
Keeping a log
A short log helps the pediatrician and therapist. Note the date, time, setting, trigger, the child’s reaction, how long it lasted and what helped. One or two lines per event are enough. After two weeks, patterns often appear: a hard time of day, a specific store, hunger or tiredness.
Support at school
If sensory problems affect learning, parents can request a school evaluation. Under the Individuals with Disabilities Education Act (IDEA), an eligible child receives an Individualized Education Program (IEP), which can include school-based OT. Children who do not qualify for an IEP may receive accommodations through a Section 504 plan. Useful accommodations include movement breaks, a wobble cushion, a seat away from the door and hallway noise, visual schedules and a quiet place to work or eat.
Brushing and weighted vests
The Wilbarger brushing protocol and weighted vests are widely used, but studies have not shown consistent benefit. If a therapist suggests them, they should be tried with clear instructions on weight, duration and technique, and stopped if the child becomes distressed or nothing changes.
When to call the pediatrician
- Loss of skills the child already had, such as words, social play or toileting
- Ongoing sleep problems that affect the day
- Self-injury such as head-banging or biting
- Speech that is clearly behind for the child’s age
- Eating so few foods that growth is affected
Frequently Asked Questions
Is sensory processing disorder an official diagnosis?
No. It is not in the DSM-5. Sensory symptoms are real and can be evaluated and addressed, but the AAP recommends looking for related conditions such as autism, ADHD or anxiety.
Who treats sensory processing difficulties?
Mostly occupational therapists, working with the child’s pediatrician. Speech-language pathologists, psychologists and developmental pediatricians may be involved depending on other needs.
How long does therapy take?
There is no fixed length. A reasonable plan sets goals, reviews them after a defined period, often a few months, and changes course if progress is lacking.
Can children outgrow sensory problems?
Many children become better at coping as they mature and learn strategies. Some sensitivities remain into adulthood, often in a milder, manageable form.
