Sensory issues are a common concern among individuals with Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). Many parents, educators, and even medical professionals often wonder: Are sensory issues a symptom of ADHD or autism?
While sensory processing difficulties can appear in both conditions, they manifest differently. Understanding these distinctions is crucial for providing the right support and interventions.
This blog will explore:
- The nature of sensory issues in ADHD and autism
- Key differences between the two conditions
- How to identify sensory processing difficulties
- Effective strategies for managing sensory challenges
By the end, you’ll have a clearer understanding of whether sensory issues stem from ADHD, autism, or a combination of both.
What Are Sensory Processing Issues?
Sensory processing issues occur when the brain struggles to receive, process, and respond to sensory input from the environment. This includes stimuli such as:
- Touch (textures, clothing, hugs)
- Sound (loud noises, sudden sounds)
- Light (brightness, flickering lights)
- Taste & Smell (food textures, strong odors)
- Balance & Movement (dizziness, need for movement)
Individuals with sensory challenges may experience hypersensitivity (over-responsiveness) or hyposensitivity (under-responsiveness) to these inputs.
Sensory Processing Issues in Autism
Sensory issues are core features of autism and are included in the diagnostic criteria for ASD. Most autistic individuals experience some degree of sensory sensitivity or sensory-seeking behaviors.
Common Sensory Challenges in Autism:
| Sensory Domain | Hypersensitive Behavior | Hyposensitive Behavior |
|---|---|---|
| Touch | Avoids certain textures, dislikes being touched | Seeks deep pressure, craves tactile input |
| Sound | Covers ears, overwhelmed by loud noises | Does not respond to name, enjoys loud sounds |
| Light | Discomfort with bright lights | Seeks bright, flashing lights |
| Taste & Smell | Avoids certain foods, reacts strongly to smells | Craves strong tastes or smells |
| Movement & Balance | Avoids swings, dislikes motion | Seeks spinning, jumping, rocking |
Why Does Autism Cause Sensory Issues?
The brains of autistic individuals process sensory input differently. This can lead to sensory overload, causing meltdowns, shutdowns, or self-soothing behaviors such as stimming (repetitive movements like rocking, hand-flapping, or spinning).
Sensory Processing Issues in ADHD
Although not a diagnostic criterion for ADHD, many individuals with ADHD experience sensory challenges. However, these sensory difficulties differ from those seen in autism.
Common Sensory Challenges in ADHD:
| Sensory Domain | ADHD Sensory Sensitivities |
|---|---|
| Touch | Easily distracted by clothing tags, seams, or itchy fabrics |
| Sound | Struggles to tune out background noise, difficulty focusing in noisy environments |
| Light | Sensitivity to bright lights, difficulty in visually overstimulating environments |
| Taste & Smell | Picky eater but less rigid than autistic individuals |
| Movement & Balance | Constantly moving, fidgeting, seeking sensory stimulation |
Why Does ADHD Cause Sensory Issues?
Sensory issues in ADHD are linked to difficulty regulating attention and sensory input. ADHD brains struggle to filter out irrelevant stimuli, making individuals more distracted by sensory input rather than overwhelmed by it (as in autism).
For example, an ADHD child may be unable to focus on a lesson due to the hum of fluorescent lights, whereas an autistic child may find the same noise physically distressing.
Key Differences Between Sensory Issues in Autism and ADHD
| Feature | Autism | ADHD |
|---|---|---|
| Sensory Sensitivity | More extreme responses (meltdowns, shutdowns) | Distracted by sensory input but not necessarily overwhelmed |
| Stimming | Common (rocking, hand-flapping, spinning) | Fidgeting but not repetitive self-soothing behaviors |
| Routine & Predictability | Prefers structure, struggles with change | Impulsive, may seek new experiences |
| Social Interactions | Difficulty understanding social cues | Impulsive and may interrupt conversations |
| Attention | Can focus intensely on specific interests | Easily distracted, struggles with sustained focus |

1️⃣ Sensory Sensitivity
You’re in a noisy, crowded shopping mall with bright lights and lots of movement. How do you react?
2️⃣ Stimming & Fidgeting
You’re waiting in line and feel restless. What do you do?
3️⃣ Routine & Predictability
Your daily schedule suddenly changes—what happens?
4️⃣ Social Interactions
You’re in a group conversation. How do you interact?
5️⃣ Attention & Focus
You’re doing a task that isn’t very interesting. How do you handle it?

How to Identify Sensory Processing Issues
Questions to Ask:
1. Does the child show extreme reactions to sensory stimuli?
- If yes, autism may be a factor.
2. Is the child easily distracted by sensory input but not overwhelmed?
- If yes, ADHD may be more likely.
3. Does the child actively seek out sensory input in a repetitive way?
- If yes, autism is more likely.
4. Does the child struggle with fidgeting and movement due to distraction?
- If yes, ADHD is more likely.
Professional Diagnosis
If sensory challenges significantly impact daily life, seeking a professional evaluation from a pediatrician, developmental psychologist, or occupational therapist can help determine whether ADHD, autism, or both are present.
Managing Sensory Issues in Autism and ADHD
For Autism:
- Create Sensory-Friendly Spaces: Minimize sensory triggers, provide calming tools like weighted blankets.
- Use Visual Schedules: Helps with predictability and reducing anxiety.
- Encourage Sensory Diets: Structured sensory activities such as deep pressure, swinging, and tactile play.
For ADHD:
- Provide Movement Breaks: Short physical activities improve focus.
- Reduce Sensory Distractions: Noise-canceling headphones, fidget tools.
- Teach Self-Regulation Skills: Deep breathing, mindfulness techniques.
Conclusion
While sensory issues are common in both autism and ADHD, they manifest differently. Autism-related sensory challenges often involve intense reactions and stimming behaviors, whereas ADHD-related sensory issues are more about distraction and difficulty filtering stimuli.
Understanding these differences can help parents, educators, and caregivers provide the right support. If you’re unsure about your child’s sensory difficulties, seeking guidance from ABA therapy providers like True Progress Therapy can offer tailored strategies to improve daily functioning and comfort.
Frequently Asked Questions
1. Can a child have both ADHD and autism?
Yes, it’s possible to have both conditions. This is known as comorbid ADHD and autism, and individuals with both may experience a mix of sensory issues from each condition.
2. How can I tell if my child’s sensory issues are severe?
If sensory difficulties interfere with daily activities, cause meltdowns or shutdowns, or lead to avoidance of normal experiences, it may indicate a significant sensory processing issue.
3. What therapies help with sensory processing challenges?
Occupational therapy (OT), sensory integration therapy, and ABA therapy are commonly used to help children develop coping mechanisms for sensory sensitivities.
