Is Sensory Processing Disorder Always Linked to Autism?

Is Sensory Processing Disorder Always Linked to Autism?

Last Updated on September 3, 2025 by John Hookway

Yes, you can have SPD even if you do not have autism. SPD means Sensory Processing Disorder. It changes how you react to things you see, hear, or feel. SPD does not only happen with autism. Most people who have SPD do not have autism.

  • Around 5% to 16% of kids in the U.S. have SPD.
  • Kids with autism have sensory problems more often, but SPD can happen in kids who do not have autism.

If you want to learn about SPD without autism, you are not the only one. Many families look for help and answers.

 

Key Takeaways

  • Sensory Processing Disorder (SPD) can happen without autism. Many people have SPD by itself.
  • It is important to notice SPD signs. Some signs are being too sensitive to sounds or textures. Other signs are not feeling pain or discomfort.
  • Therapies like occupational therapy and sensory integration therapy can help with SPD. These therapies work on making sensory skills better.
  • Making a sensory diet and changing places can help with sensory overload. Easy changes like soft lights or noise-canceling headphones help a lot.
  • Getting the right diagnosis matters. Knowing about SPD helps people and families find good support and resources.

 

SPD Without Autism

What Is SPD?

Sensory Processing Disorder (SPD) changes how you react to things around you. You might notice sounds, textures, or lights more than other people.

Sometimes, things that seem normal to others can feel too much for you. SPD can make it hard to do everyday things, especially in busy places.

Doctors and therapists use different tests to check for SPD. These tests show what you are good at and what is hard for you.

  • Sensory Integration and Praxis Tests (SIPT)
  • Miller Function and Participation Scales (MFUN)
  • Bruininks-Oseretsky Test of Motor Proficiency™ – Second Edition
  • Movement Assessment Battery for Children – Second Edition (Movement ABC-2)
  • Miller Assessment for Preschoolers (MAP)
  • Goal-Oriented Assessment of Life Skills (GOAL)

You do not need autism to have SPD. Many kids and adults have SPD without autism. SPD has its own signs and is not part of autism.

SPD vs. Autism

SPD and autism are not the same thing. Some things are alike, but they are different. Autism affects how you talk, act, and get along with others. SPD is about how you handle things you see, hear, or feel.

Some people think SPD only happens with autism. This is not true. Most people with SPD do not have autism. You can have SPD without autism and still have trouble with your senses.

Scientists have looked at how SPD and autism are different. They found each group has its own patterns.

Feature Autism Spectrum Disorder (ASD) Sensory Processing Disorder (SPD)
Sensory Under-Reactivity Higher scores Lower scores
Sensory Over-Reactivity Lower scores Higher scores
White Matter Abnormalities Present Present
Gray Matter Abnormalities Present Present
Sensory Gating Impairments Present Present
Neurochemical Imbalances Present Present
Connectivity in Sensory Regions Decreased Decreased
Impairments in Social-Emotional Present Absent

SPD and autism both have some brain differences. But SPD does not cause problems with feelings or friends. This helps doctors tell them apart.

Studies show SPD can happen by itself. For example, some kids with SPD have more trouble with touch than kids with autism. Another study found that many kids with autism have sensory problems, but SPD can happen without autism.

Here are some things people get wrong:

  • SPD and autism are not the same, even if both have sensory problems.
  • Most kids with SPD do not have autism.
  • Not all kids who are sensitive to things have autism.
  • SPD is not just a part of autism.

Knowing the difference helps you get the right help. If you have trouble with your senses but not with talking or friends, you might have SPD without autism.

 

Recognizing SPD

Signs and Symptoms

You can spot SPD by looking for certain signs. SPD shows up in many ways. Some people react a lot to sounds or lights. Others may not notice things that bother most people. The signs are not the same for everyone.

Here is a table with common signs and symptoms of SPD:

Type of Sensitivity Signs and Symptoms
Hypersensitivity – Big reactions to loud noises
– Scared of surprise touches
– Does not like hugs
– Very picky about food textures
– Very scared of climbing or falling
Hyposensitivity – Always wants to touch people
– Moves in a clumsy way
– Does not feel pain much
– Likes to play by moving a lot
– Rocks or sways often

You might feel like the world is dull or covered up. Sensory overload can happen a lot. Triggers can be hair brushing, loud sounds, bright lights, strong smells, or being touched. You may avoid some foods or clothes because they feel bad.

SPD in Non-Autistic People

SPD without autism can look different than you think. Some kids have strong reactions to sensory things, like throwing up from loud sounds or not touching some textures.

Some kids do not react to pain or changes in temperature. Tantrums or meltdowns can happen when there is too much sensory input.

You might see these behaviors:

  • Being clumsy or having trouble moving
  • Not liking some clothes
  • Gagging on some food textures
  • Not knowing where their body is

Doctors use tools like the Sensory Profile (SP), Sensory Processing Measure (SPM), and Short Sensory Profile (SSP) to find SPD in people without autism. The Sensory Integration and Praxis Test (SIPT) is used for younger kids.

It can be hard to diagnose SPD because the signs are different and can look like other problems. SPD is not its own category in the DSM-5, so it is harder to diagnose.

Knowing about SPD without autism helps you understand some behaviors. You can use this to get help and learn more about sensory processing.

 

Other Sensory Conditions

SPD as Standalone

You might ask what it means when experts say SPD is a standalone condition. SPD stands for Sensory Processing Disorder. It does not always come with other disorders.

You can have SPD without autism or ADHD. Many doctors now see SPD as its own diagnosis. This helps you get the right help and treatment.

  • Teaching people about SPD helps them understand sensory problems.
  • More research happens when SPD is seen as a real disorder.
  • You and your family can get better help when doctors diagnose SPD correctly.

Getting the right diagnosis is important. It helps you know what is happening. You can then find therapies that work for you. SPD sometimes shows up with other conditions, but most kids with SPD do not have autism. ADHD is more common with SPD than autism.

Sensory Issues in ADHD

Sensory problems can also happen in ADHD. Some kids with ADHD react a lot to sounds, textures, or movement. About 66% of kids with ADHD have different sensory processing. Around 40% of people with ADHD have these problems.

Here is a table that shows how sensory issues in ADHD are different from SPD:

Aspect ADHD SPD
Nature of Disorder A mix of traits. Sensory differences as a main trait.
Brain Mechanisms Changes in frontal brain areas. Reduced white matter for sensory processing.
Response to Sensory Input Overstimulation may cause anxiety. Too much sensory input leads to anxiety.
Treatment Approaches Medication and behavioral therapy. Lifestyle changes and therapy.
Sensory Processing May improve with new activities. May crave more sensory input.

You can spot ADHD if you see quick actions that do not change with sensory input. Kids with ADHD often want new things and activities. SPD is different.

You may calm down with sensory input or feel worse with new sensory experiences. Sensory problems in SPD do not get better with ADHD medicine.

If you notice sensory problems in yourself or your child, remember SPD without autism can happen. You can get help and learn more about these conditions.

 

Managing SPD Without Autism

Therapy and Support

If you have SPD but not autism, there are many ways to get help. Occupational therapy is a top choice for many people. An occupational therapist helps you learn about your sensory needs. You can practice new ways to deal with sounds, textures, and lights.

Sensory integration therapy uses fun activities like swinging or deep pressure. These activities help your brain handle sensory input better.

A sensory diet is a plan for daily activities. It might include jumping, squeezing a stress ball, or taking quiet breaks. You can also change your space to feel more comfortable.

For example, you might use soft lights or wear noise-canceling headphones. Cognitive Behavioral Therapy (CBT) can help you with stress or anxiety from sensory overload. Sometimes, doctors may give medicine if you have other health problems.

You can get support from different places:

  • Occupational therapists help both kids and adults.
  • Groups like the Child Mind Institute and National Institute on Aging share helpful tips.
  • Adults can join support groups or find advice on picking a therapist.

You do not have to handle SPD by yourself. There is support for families and adults at every step.

Everyday Strategies

You can use easy tips every day to help with SPD. Doing regular exercise, like walking, helps your body handle sensory input. Compression clothes can help if you are sensitive to touch. Make your home or work space calm with soft lights and quiet spots.

Having a routine can make you feel safe and in control. Creative things like painting or listening to music can help you relax.

Meditation or slow, gentle massage can also help you feel calm. Try to notice what makes your senses feel too much and plan how to deal with it.

Here are some tips for daily life:

  • Take breaks in quiet places when you feel stressed.
  • Use things like fidget toys or weighted blankets.
  • Tell your family what you need so they can help you.

Managing SPD without autism means finding what works best for you. With good support and smart strategies, you can feel better and enjoy your daily life more.

You can have SPD even if you do not have autism. Many experts agree that SPD is a real condition. If you think you might have SPD, you can do a few things:

  1. Ask a healthcare professional, like an occupational therapist, for help.
  2. Tell them about your sensory problems and how you act.
  3. Work with them to make a plan that helps you.

Experts say you should take movement breaks, use bright visual schedules, and give yourself time to get used to new things.
Here is what research says about results:

Outcome Measure Percentage of Individuals in ‘Typical’ Range Description
Sensory Processing Status 51% Many people with SPD get better after therapy and handle sensory problems.

You can learn to handle SPD and have a good life, even if you do not have autism.
