SPD vs ADHD in Children: How to Tell the Difference (Utah)

By Lauren | Salt Lake Occupational Therapy

Last updated: October 26, 2026

If you’re wondering whether your child’s big reactions, fidgeting, or difficulty focusing point to Sensory Processing Differences (SPD) or Attention-Deficit/Hyperactivity Disorder (ADHD), you’re not alone. This article may help parents and caregivers who see overlapping signs at home or school. You can expect clear, everyday examples, how pediatric occupational therapy (OT) fits in, and gentle ideas to try. We won’t diagnose or is not a substitute for individualized medical care here—ADHD and other conditions require evaluation by qualified professionals. A practical next step is to jot down patterns you notice and consider a supportive OT consultation to explore regulation and routines.

SPD vs ADHD: What each term means

Sensory Processing Differences (SPD): Many children experience differences in how their nervous systems notice, process, and respond to sensory input (sound, touch, movement, light, taste, smell, interoception). These differences can lead to over-responsivity (e.g., meltdowns with noise), under-responsivity (e.g., slow to register name), or sensory seeking (e.g., constant spinning). Sensory processing as a concept is widely discussed in pediatric occupational therapy and family resources such as the STAR Institute for Sensory Processing provide helpful education. SPD is not currently an official DSM-5 diagnosis, but sensory processing challenges are real, affect daily life, and can be addressed through supportive strategies.
Attention-Deficit/Hyperactivity Disorder (ADHD): ADHD is typically characterized by persistent patterns of inattention and/or hyperactivity-impulsivity that interfere with functioning across settings. For family-friendly clinical overviews and care pathways, see the American Academy of Pediatrics’ resources on ADHD (AAP).

Both can affect attention, behavior, and emotions—but for different underlying reasons. That’s why a careful, team-based look matters.

Similar behaviors, different roots

It’s common to see overlap. Here are examples of how the same outward behavior may come from different internal needs.

The wiggly mover

Possible SPD driver: A child seeks vestibular or proprioceptive input to feel organized and alert, so they stand to work, push into walls, or jump between tasks. When you provide heavy-work input (carrying books, animal walks) first, their focus may improve.
Possible ADHD driver: A child has difficulty sustaining attention and inhibiting impulses across most tasks and contexts, even when sensory needs are met. They leave their seat and talk out of turn during quiet and active activities alike. Consistent patterns across settings point to ADHD features supported by clinical guidelines (AAP).

The child who “can’t listen”

Possible SPD driver: Background hum (HVAC), cafeteria clatter, or itchy tags overwhelm the nervous system. The brain is busy filtering sensations, so following directions is hard. Reducing sensory load or offering headphones can unlock listening.
Possible ADHD driver: Distractibility shows up regardless of sensory load. Even in a quiet room with preferred seating, attention drifts quickly across tasks. Structured supports and behavior plans may help.

Big emotions and meltdowns

Possible SPD driver: A sudden blender noise leads to a fight/flight response; the child covers ears, cries, or bolts. When you preview sounds, use visual timers, and co-regulate with deep pressure, calm returns faster.
Possible ADHD driver: Frustration tolerance is low when tasks are boring or complex; impulsive reactions (shouting, grabbing) occur even without a sensory trigger. Patterns appear across many activities and environments.

If you ever worry about safety (e.g., running into streets, self-harm, or aggression that could injure), seek urgent support from your pediatrician, school team, or emergency services.

Why they can co-occur—and why that matters

Children can experience both sensory processing differences and ADHD. Sensory input influences arousal levels, while ADHD involves executive function (working memory, inhibition, planning). When both are present, a child may need layered supports: sensory strategies to achieve the “just-right” alertness and executive-function scaffolds (visual schedules, chunked directions) to sustain task engagement. The CDC’s Act Early materials can help parents reflect on age-expected self-regulation and attention while noting individual variability (CDC milestones).

How pediatric OT helps you sort it out

Occupational therapists focus on participation in daily routines—getting dressed, mealtimes, play, school, and bedtime. Through observation, caregiver interview, and play-based assessment, we explore:

What sensory inputs help your child feel calm, focused, or joyful
Which contexts reliably trigger stress or impulsivity
How motor planning, posture, and body awareness support attention
What environmental tweaks (lighting, seating, sound) change behavior

OTs share family-centered, evidence-informed strategies to support sensory processing and regulation so children can participate more comfortably (AOTA). If ADHD is suspected, we’ll encourage you to follow up with your pediatrician or a qualified clinician for diagnostic evaluation while continuing supportive routines at home and school.

A simple home and school checklist you can start today

Try these low-risk, supportive steps for one to two weeks and note changes.

Match movement to focus: Offer “heavy work” (wall push-ups, crab walks, carrying laundry) 5–10 minutes before seated tasks. If focus increases, sensory input may be a helpful gateway.
Adjust the soundscape: Test options like soft background music, white noise, or noise-reducing headphones. Observe if directions are easier to follow with fewer competing sounds.
Visuals and routines: Post a two- to three-step picture schedule for mornings and homework. If predictability helps, add checklists or timers.
Right-size the seat: Provide a footrest, a slanted surface, or a wobble cushion—one change at a time—to see what supports body organization.
Breaks with purpose: Offer brief, planned movement or sensory breaks instead of breaks only after dysregulation. Track which breaks reset attention best.

If strong patterns emerge only in high-sensory settings (cafeteria, assemblies), sensory modulation may be a primary factor. If challenges appear in most settings despite sensory supports, consider discussing ADHD assessment with your pediatrician (AAP ADHD overview).

What to expect with OT in Salt Lake City, Utah

At Salt Lake Occupational Therapy, sessions are play-based and collaborative. Families in Salt Lake City, Utah can expect:

A strengths-first approach that celebrates your child’s interests
Coaching so strategies fit your routines and values
School collaboration when appropriate (with your consent)
Practical tools you can use the same day

When sensory modulation and arousal are central needs, we may recommend individualized regulation plans and environmental adjustments. To learn more about how we support regulation across home and school routines, see our service page: Regulation Support for Kids in Salt Lake City.

If you’re ready to talk through your child’s specific patterns and goals, you can book a consultation with Salt Lake Occupational Therapy.

When to loop in other professionals

Pediatrician: For developmental concerns, sleep or nutrition issues, or if you’re considering ADHD evaluation.
School team: When participation or learning is affected. Share your observations and ask about accommodations.
Mental health clinician: For anxiety, mood concerns, or persistent behavior challenges that impact family life.

OT works well alongside these supports; the goal is a coordinated plan that helps your child participate more comfortably.

Key takeaways for busy parents

Similar behaviors can have different reasons. Sensory needs often fluctuate with context; ADHD traits tend to occur across many settings.
Try small experiments (movement first, adjust sound, use visuals) and track what helps most.
Consider both/and: some children experience sensory processing differences and ADHD.
You don’t have to figure this out alone—support is available in Salt Lake City.
