Sensory Processing Disorder (SPD) is a condition that affects how the brain processes sensory information like touch, sound, and movement. It's commonly seen in developmental conditions like autism spectrum disorder WebMD.
There is a significant overlap between sensory integration disorder and autism. According to the STAR Institute for Sensory Processing in Colorado, over 80% of children with autism also have SPD Autism Parenting Magazine. Additionally, a study cites that 90-95% of individuals diagnosed with autism spectrum disorder (ASD) have atypical sensory experiences, with abnormal responses to tactile stimulation being a very frequent finding NCBI.
While these percentages are high, it's important to note that not all children with SPD have autism. SPD is said to affect approximately 5-16% of school-aged children in general Autism Parenting Magazine.
Recognizing SPD in individuals with autism can be challenging due to the overlap of symptoms. These can include difficulties with sensory processing, such as hyper- or hypo-reactivity to sensory stimuli, which is recognized in the DSM-V as a key characteristic of ASD NCBI.
Individuals with SPD may exhibit behaviors such as avoiding certain textures, being overwhelmed by loud noises, or seeking out specific sensory experiences. These sensory processing difficulties can exacerbate social communication deficits and increase the frequency of restrictive and repetitive behavior NCBI Bookshelf.
Early recognition of SPD can help in implementing appropriate interventions like occupational therapy for autism or sensory integration therapy for autism, which can significantly improve the individual's ability to cope with sensory stimuli.
Understanding the intricate connection between sensory integration disorder and autism can help in better recognizing and managing these conditions. This knowledge can guide therapeutic strategies, like play therapy for autism, and provide a more comprehensive approach to supporting individuals with ASD and SPD.
Sensory integration therapy, including Ayres Sensory Integration (ASI), is pivotal in the management of sensory symptoms in individuals with autism spectrum disorder (ASD). This therapeutic approach combines physical and cognitive therapeutic tools to enhance the individual's sensory symptoms in a clinical setting Healthline.
The approach of sensory integration therapy primarily targets autistic children aged 3 to 11. It aims to improve their communication, cognition, self-development in younger children, and social, behavioral, and motor skills in adolescents. The therapy seeks to manage both immediate and long-term sensory symptoms in individuals with ASD Healthline.
Sensory integration therapy (SIT) is a clinic-based approach that concentrates on the therapist-child relationship. This approach uses play-based sensory motor activities to address sensory-motor factors specific to the child, thereby improving their ability to process and integrate sensation NCBI Bookshelf. For more details about play-based therapies for autism, check out our article on play therapy for autism.
Occupational therapists play a significant role in managing sensory symptoms through sensory integration therapy, especially for those with ASD. The American Occupational Therapy Association (AOTA) emphasizes the crucial role of occupational therapists in assisting individuals with ASD in managing sensory symptoms Healthline.
These professionals work one-on-one with individuals with autism, guiding them through various sensory activities designed to help them better respond to sensory stimuli. The therapy sessions are often fun and engaging, incorporating games and activities that encourage sensory exploration. The ultimate goal of the occupational therapist is to help the individual develop better coping mechanisms for managing their sensory symptoms in everyday life.

The intersection of sensory processing disorder and autism is a significant area of study within the field of developmental disorders. This section will explore the prevalence of these overlapping conditions and the impact they can have on the daily lives of individuals with autism.
Sensory processing disorder (SPD) is commonly seen in developmental conditions like autism spectrum disorder (ASD). In fact, the STAR Institute for Sensory Processing in Colorado notes that over 80% of children with autism also have SPD [1]. Yet, it's essential to understand that not all children with SPD have autism, and SPD can affect approximately 5-16% of school-aged children in general.
Furthermore, difficulty in processing sensory information is common in autism, with estimates suggesting that 90–95% of individuals with autism experience some form of sensory processing difficulties. This prevalence underscores the significant overlap between sensory integration disorder and autism and highlights the need for effective therapeutic strategies, such as occupational therapy for autism and sensory integration therapy for autism.
The co-occurrence of SPD and ASD can significantly impact an individual's daily life. SPD can exacerbate the social communication deficits often associated with autism, increase the frequency of restrictive and repetitive behavior, and occur due to impaired regulation of central nervous system arousal.
These sensory processing difficulties can manifest in various ways, such as hypersensitivity or hyposensitivity to sensory stimuli, difficulty with motor skills, or trouble with processing and responding to sensory information. These challenges can affect a wide range of activities, from participating in social events to performing routine tasks, magnifying the challenges already presented by autism.
Given the significant impact of SPD on the lives of individuals with autism, it's crucial to provide the necessary support and intervention strategies to help manage these conditions. Therapies such as occupational therapy or play therapy for autism can provide effective means of addressing the unique needs of these individuals and improving their quality of life. Through continued research and development of therapeutic strategies, it is hoped that individuals with SPD and ASD can lead fulfilling and enriched lives.
In the realm of therapies for sensory integration disorder and autism, one question that often arises is the effectiveness of sensory integration therapy. This therapy, primarily used in autistic children aged 3 to 11, focuses on improving various skills, including communication, cognition, self-development in younger children, and social, behavioral, and motor skills in adolescents. The therapy aims to help manage both immediate and long-term sensory symptoms in individuals with autism spectrum disorder.
Studies have shown that Sensory Integration Therapy (SIT) has led to improvements in client-oriented goals. Some have reported positive effects of SIT on the Goal Attainment Scale (GAS), which measures the degree to which a patient's personal goals for therapy have been achieved.
Additionally, one study reported a significant decrease in autistic mannerisms in the SI group, indicating a potential impact of SI interventions on the core symptoms of ASD [4].
Despite these promising findings, it's important to note the challenges and limitations associated with sensory integration therapy. At present, the evidence base supporting the use of SIT for children with autism is considered low quality and insufficient to recommend the treatment.
The methodological issues include poorly described interventions, small sample sizes, lack of long-term follow-up, and limited description of usual care [2]. This highlights the need for further, more rigorous research to fully understand the potential benefits and limitations of sensory integration therapy.
Understanding the effectiveness of this therapy is crucial for individuals with autism and their caregivers, as it can directly impact the choice of therapies they consider. While sensory integration therapy offers some potential benefits, it's important to approach it with a balanced perspective, considering both the promising findings and the current limitations.

In the context of sensory integration disorder and autism, it’s crucial to delve into the various sensory systems and how their dysfunction can manifest.
The tactile system, which includes nerves under the skin's surface that send information to the brain related to light touch, pain, temperature, and pressure, plays a significant role in sensory processing. Dysfunction in this system can lead to the misperception of touch and/or pain, which can be hyper-sensitive or hypo-sensitive. This dysfunction may result in self-imposed isolation, irritability, distractibility, and hyperactivity.
A common manifestation of tactile dysfunction is tactile defensiveness, where an individual is extremely sensitive to light touch. This can lead to abnormal neural signals being sent to the brain's cortex, causing over-stimulation and difficulties in behavior organization and concentration.
The vestibular system, responsible for detecting movement and changes in the position of the head, can also face dysfunction. This can manifest as hypersensitivity or hyposensitivity to movement. Hypersensitivity may cause fearful reactions to ordinary movement activities, trouble learning motor tasks like climbing stairs, and apprehension in walking on uneven surfaces.
On the other hand, hypo-reactive vestibular systems may lead individuals to actively seek intense sensory experiences such as body whirling and spinning. These manifestations can affect a wide range of everyday activities, posing challenges to individuals with autism [5].
The proprioceptive system, although not covered in the extra context, is another important sensory system that often dysfunctions in individuals with autism. This system helps us understand where our bodies are in space and how we are moving. Dysfunction in the proprioceptive system can lead to difficulties in coordination, balance, and awareness of body position, significantly impacting daily activities and overall quality of life.
Understanding these sensory dysfunctions is paramount in developing effective therapeutic strategies, such as sensory integration therapy and occupational therapy for autism. These therapeutic approaches aim to help individuals with autism better manage their sensory challenges and improve their ability to engage in everyday activities.
As we continue to understand the relationship between sensory integration disorder and autism, future research and considerations are vital. These include analyzing the neurobiological basis, conducting genetic studies in Autism Spectrum Disorders (ASD), and developing therapeutic strategies.
Sensory integration is an innate neurobiological process involving the integration and interpretation of sensory stimulation from the environment by the brain. Sensory integrative dysfunction, on the other hand, is a disorder where sensory input is not integrated or organized appropriately in the brain, potentially causing problems in development, information processing, and behavior [5].
Genetic mouse models have been generated with knockout and humanized knockin mutations in many ASD-associated genes. These models aim to understand the neurobiological bases of sensory processing in ASD. These models may help in identifying early biomarkers and developing novel therapeutic strategies for sensory abnormalities in ASD.
There is growing evidence that sensory symptoms anticipate social and communication deficits in infants later diagnosed with autism. Abnormal sensory traits could be predictive of the autistic condition, and sensory deficits are documented as early as the 6th month of life in infants later diagnosed with autism [6].
Further genetic studies in ASD can deepen our understanding of these early signs, leading to earlier diagnosis and intervention opportunities.
Understanding sensory processing in ASD is essential for developing effective therapeutic strategies. Sensory processing disorder (SPD) is common among children with ASD, with reports ranging from 42% to 88% in the literature [4].
Studies have shown that tactile sensitivity is impaired in both adults and children with ASD, with some studies indicating that tactile detection is normal in autism. The differences in tactile detection results may stem from the type of stimulation used and its location.
With this knowledge, professionals offering occupational therapy for autism and sensory integration therapy for autism can adapt their approaches to address these specific sensory challenges.
As we continue to learn more about the relationship between sensory integration disorder and autism, these areas of focus can help guide future research and therapy development efforts. In doing so, we can better support individuals with autism in managing their unique sensory experiences.
