Sensory Processing Disorder vs. Autism
Unraveling sensory processing disorder vs. autism: Understand the overlaps and distinctions between these neurological conditions.
Understanding Sensory Processing Disorder
Sensory Processing Disorder (SPD) is a neurodevelopmental condition that affects how the brain processes and responds to sensory information from the environment. It involves difficulty detecting, modulating, and interpreting sensory stimuli, such as loud noises, bright lights, or other things that stimulate one or more of the five senses [1]. Individuals with SPD may have atypical sensory responses and difficulties in sensory integration, which refers to the brain's ability to combine and make sense of different sensory inputs such as touch, sound, smell, taste, and movement.
Definition and Characteristics
Sensory Processing Disorder is not recognized as a stand-alone disorder, but many experts believe that it should be. It is often a comorbid symptom of Autism Spectrum Disorder (ASD), but not all children with sensory processing disorder have autism. Individuals with SPD may exhibit a wide range of symptoms, which can vary in severity and presentation. Some common characteristics of SPD include:
- Hyper- or hypo-reactivity to sensory input: Individuals may be overly sensitive or under-responsive to certain stimuli, such as touch, sound, taste, smell, or movement.
- Sensory-seeking or sensory-avoidant behaviors: Some individuals may actively seek out sensory stimulation, while others may actively avoid or become overwhelmed by certain sensory experiences.
- Difficulties with sensory discrimination: Individuals may struggle to distinguish between different sensory stimuli or have difficulty organizing and prioritizing sensory information.
- Challenges in daily functioning: Sensory processing difficulties can impact various aspects of daily life, including self-care, social interactions, and academic performance.
Prevalence in the General Population
Sensory Processing Disorder affects an estimated 5%–16% of children in the United States. It is important to note that SPD is commonly associated with other conditions. It occurs in about 90% of people living with Autism Spectrum Disorder (ASD) and about 50-64% of people living with Attention Deficit Hyperactivity Disorder (ADHD). However, it is essential to recognize that not all children with sensory processing disorder have autism. Sensory processing difficulties can occur independently or in conjunction with other conditions, highlighting the need for individualized evaluations and interventions.
Exploring Autism Spectrum Disorder
Autism Spectrum Disorder (ASD) is a neurological and developmental disorder that affects how a person communicates, learns, and behaves. It is estimated to affect 1 in 44 children in the United States, with boys being roughly four times as likely to be diagnosed compared to girls.
Overview of ASD
ASD is a complex condition that encompasses a wide range of symptoms and abilities. It is characterized by challenges in social interaction, communication, and repetitive behaviors. Individuals with ASD may also exhibit sensory processing difficulties, which can impact their daily lives.
The symptoms of ASD can vary greatly from person to person, ranging from mild to severe. Some individuals may have exceptional abilities in certain areas, such as music, art, or mathematics, while others may struggle with intellectual functioning. The onset of symptoms is typically observed in early childhood, often before the age of three.
Diagnosis and Statistics
Diagnosing ASD involves a comprehensive evaluation process that includes assessments from healthcare professionals, educators, and other specialists. The evaluation takes into account the individual's behavior, communication skills, and developmental history. In 2020, an estimated 1 in 36 eight-year-old children received an ASD diagnosis, according to the Centers for Disease Control and Prevention (CDC).
It is important to note that sensory processing difficulties are commonly observed in individuals with ASD. Over 80% of children with autism also have sensory processing disorder (SPD), according to the DSM-5, which includes hyper- or hypo-reactivity to sensory input" as one of the behaviors associated with ASD. However, it is worth mentioning that SPD can also occur independently or be associated with other disorders such as ADHD.
Understanding the complexities of ASD is crucial for providing appropriate support and interventions to individuals on the autism spectrum. By recognizing the unique challenges and strengths of individuals with ASD, we can work towards creating a more inclusive and understanding society.
Overlapping Symptoms
When it comes to Sensory Processing Disorder (SPD) and Autism Spectrum Disorder (ASD), there are overlapping symptoms that can make it challenging to differentiate between the two conditions. This section will explore the shared neurological networks and behavioral overlaps between SPD and ASD.
Shared Neurological Networks
Sensory Processing Disorder and Autism Spectrum Disorder share the same neurological networks and brain structures, which can lead to behaviors that mimic each other, causing overlap in symptoms. The brain regions involved in sensory processing, such as the amygdala, prefrontal cortex, and sensory-specific areas, show similarities in both conditions.
These shared neurological networks can contribute to difficulties in sensory processing and integration, leading to challenges in how individuals with SPD and ASD respond to and interpret sensory information from their environment.
Behavioral Overlaps
The behavioral overlaps between Sensory Processing Disorder and Autism Spectrum Disorder further contribute to the difficulty in distinguishing between the two conditions. Both SPD and ASD can manifest similar sensory sensitivities and responses, such as hypersensitivity (over-responsiveness) and hyposensitivity (under-responsiveness) to various stimuli.
Sensory issues, including atypical responses to touch, sound, smell, taste, and movement, are common in individuals with ASD. These sensory sensitivities can impact daily functioning and contribute to difficulties in social interactions, communication, and behavior.
It's important to note that while there are overlapping symptoms, Sensory Processing Disorder and Autism Spectrum Disorder are separate conditions that may coexist. Each individual's experiences and challenges with sensory processing can vary, and a comprehensive evaluation is necessary to differentiate between the two and provide appropriate interventions and support [7].
Understanding the shared neurological networks and behavioral overlaps helps professionals in the field of developmental disorders to navigate the complexities of these conditions and provide accurate diagnoses and tailored treatment plans for individuals with SPD and ASD.
Sensory Processing in Autism
When discussing sensory processing, it's important to understand how it relates to Autism Spectrum Disorder (ASD). Sensory challenges are common in individuals with autism and are included in the diagnostic criteria for ASD [6]. These challenges can significantly impact daily functioning and the overall experience of individuals with autism.
Sensory Challenges in ASD
Autistic individuals often experience both hypersensitivity (over-responsiveness) and hyposensitivity (under-responsiveness) to various stimuli, leading to unique sensory sensitivities. Hypersensitivity can manifest as heightened responses to bright lights, certain light wavelengths (e.g., LED or fluorescent lights), sounds, smells, textures, and tastes. These stimuli can be overwhelming for individuals with autism, resulting in sensory avoidance behaviors such as covering ears to avoid loud sounds or pulling away from physical touch.
On the other hand, hyposensitivity is characterized by a reduced response to sensory input. Autistic individuals who are hyposensitive may have difficulty recognizing sensations like hunger or pain and may seek out intense sensory experiences like loud noises, bright lights, and vibrant colors. Sensory-seeking behaviors, such as making loud noises, touching objects, or rocking back and forth, are common ways for individuals to seek additional sensory input.
Impact on Daily Functioning
Sensory challenges can have a significant impact on the daily lives of individuals with autism. Sensory overload occurs when intense sensory stimuli overwhelm an individual's ability to cope, leading to feelings of anxiety, a need to escape, or difficulty communicating. This overload can be triggered by a single event or build up over time due to daily efforts to cope with sensory sensitivities. In some cases, the overload may result in shutting off other brain functions, such as speech and decision-making.
The impact of sensory challenges can vary from person to person, but it can affect various aspects of daily functioning, including social interactions, communication, and participation in the community. Understanding and accommodating sensory issues are crucial for creating an environment that eases discomfort and provides opportunities for autistic individuals to learn, socialize, communicate, and thrive.
Accommodations for sensory challenges may involve modifying the environment, using tools and strategies, or creating new habits and routines tailored to individual sensory needs [6]. These accommodations can vary across different settings, as individuals with autism may have different sensory needs in different environments.
By recognizing and addressing sensory challenges in individuals with autism, we can help create a more inclusive and supportive environment that enhances their overall well-being and quality of life.
Diagnosis and Evaluation
When it comes to distinguishing between Sensory Processing Disorder (SPD) and Autism Spectrum Disorder (ASD), a comprehensive evaluation process is essential. While there can be overlapping symptoms and behavioral similarities, it is crucial to differentiate between the two to provide appropriate support and intervention for individuals.
Differentiating between SPD and ASD
Sensory Processing Disorder and Autism Spectrum Disorder share the same neurological networks and brain structures, which can lead to behaviors that mimic each other, causing overlap in symptoms. However, there are certain distinctions that can help in distinguishing between the two:

Comprehensive Evaluation Process
To accurately diagnose and differentiate between SPD and ASD, a comprehensive evaluation is necessary. This evaluation process typically involves the following steps:
- Clinical Interview: A thorough history-taking session with the individual and their caregiver to gather information about their sensory experiences, behaviors, and developmental milestones.
- Observation and Assessment: Clinical professionals observe the individual's behaviors and responses in various sensory situations. Standardized assessments, such as the Sensory Integration and Praxis Tests, may be used to measure sensory processing abilities.
- Evaluation of Other Domains: Assessments may be conducted to evaluate other areas of development, including social communication, language skills, and cognitive abilities. This helps in ruling out or identifying any coexisting conditions.
- Collaborative Approach: The evaluation process often involves a multidisciplinary team, including occupational therapists, speech-language pathologists, psychologists, and developmental pediatricians. Collaboration among these professionals ensures a comprehensive evaluation and accurate diagnosis.
By conducting a thorough evaluation and considering the individual's sensory experiences, behaviors, and developmental history, professionals can differentiate between SPD and ASD. This distinction is crucial in providing appropriate interventions and support tailored to the individual's specific needs.
Understanding the differences and similarities between SPD and ASD is crucial in order to provide individuals with the proper support and interventions they require. A comprehensive evaluation process, conducted by a multidisciplinary team, helps in accurately diagnosing and differentiating between the two conditions.
Management and Treatment
When it comes to the management and treatment of sensory processing disorder (SPD) and autism spectrum disorder (ASD), a variety of approaches and therapies are available to help individuals navigate their sensory challenges. These interventions aim to improve daily functioning and enhance the overall quality of life for those affected.
Sensory Integration Therapies
Sensory integration therapy is a commonly used approach for individuals with sensory processing difficulties, including those with SPD and ASD. This therapy focuses on helping individuals process and respond to sensory stimuli in a more adaptive and organized manner. The Developmental, Individual Difference, Relationship-based (DIR) model, which includes the "floor-time" method, is one example of a sensory integration therapy.
The goal of sensory integration therapy is to provide individuals with opportunities to engage in sensory-rich activities in a controlled and supportive environment. This allows them to gradually develop the ability to process and integrate sensory information more effectively. Therapy sessions may involve activities such as swinging, jumping, deep pressure touch, and other sensory experiences tailored to the individual's needs.
Individualized Approaches
In addition to sensory integration therapies, individualized approaches are often recommended to address the specific needs and challenges of individuals with SPD and ASD. These approaches may involve a combination of behavioral interventions, speech therapy, occupational therapy, and other specialized interventions based on the individual's unique sensory profile and areas of difficulty.
For individuals with ASD, treatment typically includes a comprehensive approach that addresses the core symptoms and associated challenges. This may involve social skills training, communication therapies, behavioral interventions, and educational support. Occupational therapy can also play a significant role in helping individuals with ASD develop sensory regulation skills and improve their ability to engage in daily activities.
It is important to note that while sensory integration therapies and individualized approaches can be beneficial for many individuals with SPD and ASD, the effectiveness of these interventions may vary from person to person. Therefore, it is crucial to work closely with healthcare professionals, therapists, and educators to develop a personalized treatment plan that addresses the specific needs and goals of each individual.
By utilizing sensory integration therapies and individualized approaches, individuals with SPD and ASD can develop strategies to better manage their sensory challenges and improve their overall daily functioning. These interventions aim to promote adaptive responses to sensory stimuli, enhance social interactions, and support individuals in reaching their full potential.
