Autism Spectrum Disorder (ASD) and Sensory Processing Disorder (SPD) can share some overlapping traits, particularly related to sensory experiences, but they are distinct conditions. Recognizing the differences is important for guiding appropriate support, therapy, and understanding.
Sensory Processing Disorder (SPD)
involves differences in how the nervous system receives, organizes, and responds to sensory information. A person with SPD may be over-responsive (hypersensitive) or under-responsive (hyposensitive) to everyday sensations such as sound, touch, taste, or movement. This can lead to strong avoidance or seeking of sensory input. Importantly, SPD does not inherently include the social communication challenges or restricted/repetitive behaviors central to an autism diagnosis.
Autism Spectrum Disorder (ASD)
is a neurodevelopmental condition characterized by persistent differences in social communication and interaction, along with restricted interests and repetitive behaviors. While many autistic individuals also experience sensory processing differences, these occur within the broader context of autism’s core features.
In short: many autistic people have sensory processing differences, but not everyone with SPD is autistic. An accurate assessment by a qualified professional can help clarify a child’s profile and guide the most supportive next steps.
At Happy Haven ABA, we provide personalized assessments and therapy plans that consider the whole child—including sensory needs, communication strengths, and behavioral goals. Whether your child has autism, SPD, or both, we work with your family to build a supportive, effective plan for growth.
Frequently Asked Questions
Are autism and SPD the same?
No. Autism is a neurodevelopmental condition that includes social communication differences and repetitive behaviors, often alongside sensory sensitivities. SPD primarily involves difficulty processing sensory information (sound, touch, movement, etc.) without the core social-communication features of autism.
Can a child have both conditions?
Yes. It’s common for autistic individuals to also experience sensory processing differences. A thorough evaluation can help identify each area of need to inform a comprehensive support plan.
What are key signs of SPD?
Signs may include extreme reactions to sounds, textures, or smells; difficulty with balance or coordination; avoiding or intensely seeking movement; and being easily overwhelmed by busy environments. These challenges are primarily sensory-based and can occur independently of autism.
