What Does Autism Do to Your Body?

While autism primarily affects a person's ability to communicate and interact with others, it can also have physical effects on the body.

Understanding Sensory Processing Disorder (SPD)

Sensory Processing Disorder (SPD) is a condition that affects how the brain processes and responds to sensory information from the environment. Individuals with SPD may have difficulty organizing and integrating sensory input, leading to challenges in daily life. This section will provide an overview of what sensory processing disorder is and the link between autism and SPD.

What is Sensory Processing Disorder?

Sensory Processing Disorder, also known as sensory integration dysfunction, is a neurological condition that affects the way the brain receives, processes, and responds to sensory information. Sensory information refers to the signals received from the five senses: sight, hearing, taste, touch, and smell, as well as from the body's proprioceptive and vestibular systems.

In individuals with SPD, the brain may have difficulty interpreting and responding appropriately to sensory input, resulting in atypical reactions or responses. This can manifest as hypersensitivity (overresponsiveness) or hyposensitivity (underresponsiveness) to sensory input, or a combination of both.

Common symptoms of sensory processing disorder include:

  • Overresponsiveness to sensory stimuli, such as being easily overwhelmed by loud noises, bright lights, or certain textures.
  • Underresponsiveness to sensory stimuli, such as not noticing when touched or having a high pain threshold.
  • Seeking sensory input, such as constantly seeking movement or engaging in repetitive behaviors.
  • Avoidance of certain sensory experiences or environments.

It's important to note that sensory processing disorder can occur in individuals without autism as well. However, it is particularly prevalent in individuals on the autism spectrum.

The Link Between Autism and SPD

Sensory processing disorder often coexists with autism spectrum disorder (ASD). In fact, research suggests that up to 80% of individuals with autism experience sensory processing challenges. The sensory difficulties associated with autism can significantly impact an individual's daily functioning and quality of life.

While the exact relationship between autism and SPD is not fully understood, it is believed that sensory processing difficulties in autism may arise from differences in the way the brain processes and filters sensory information.

The atypical sensory responses and sensitivities experienced by individuals with autism can contribute to various challenges, including difficulties with communication, social interactions, behavior regulation, and learning.

Understanding the relationship between autism and sensory processing disorder is crucial in developing effective strategies and interventions to support individuals with autism. By creating a sensory-friendly environment, providing sensory integration therapy, and utilizing supportive tools and techniques, it is possible to help individuals with autism better manage their sensory challenges and improve their overall well-being.

In the following sections, we will explore the sensory sensations experienced by individuals with autism and the common challenges associated with sensory processing disorder.

Sensory Sensations in Autism

Individuals with autism often experience sensory processing differences, which can manifest as either hypersensitivity or hyposensitivity to sensory input. These sensory sensations play a significant role in how individuals with autism perceive and interact with the world around them.

Hypersensitivity to Sensory Input

Hypersensitivity, also known as sensory overresponsivity, refers to an increased sensitivity to sensory stimuli. People with autism who are hypersensitive may have intense reactions to ordinary sensory experiences that others find tolerable. This heightened sensitivity can affect various sensory modalities, including:

  • Auditory Sensitivity: Individuals may be extremely sensitive to sounds, finding certain noises overwhelming or painful. Common examples include loud conversations, sirens, or even everyday sounds like the ticking of a clock.
  • Visual Sensitivity: Bright lights, fluorescent lighting, or patterns may cause discomfort or visual disturbances for individuals with hypersensitivity to visual input. Busy or cluttered visual environments can also be overwhelming.
  • Tactile Sensitivity: Some individuals may be hypersensitive to touch, finding certain fabrics, tags on clothing, or gentle touches uncomfortable or even painful. This increased sensitivity can impact activities such as grooming, wearing certain textures, or participating in activities involving tactile input.
  • Gustatory and Olfactory Sensitivity: Hypersensitivity to taste and smell can result in an aversion to certain foods or strong odors. Individuals may have a limited diet due to the overwhelming taste or smell of certain foods. Strong scents, such as perfumes or cleaning products, can also be distressing.
  • Proprioceptive and Vestibular Sensitivity: Proprioception refers to the body's sense of position and movement, while the vestibular system contributes to balance and spatial orientation. Individuals with hypersensitivity in these areas may be sensitive to certain movements, experiences of being off balance, or rough touch.

Hyposensitivity to Sensory Input

On the other hand, some individuals with autism may experience hyposensitivity, also known as sensory underresponsivity. This means they have a decreased sensitivity to sensory input and may require more intense or frequent stimulation to achieve the same level of sensory awareness as others. Areas where hyposensitivity may be observed include:

  • Auditory Sensitivity: Individuals may have difficulty filtering or processing sounds, leading to a reduced response to auditory stimuli. They may seem oblivious to certain noises or have a high threshold for detecting sounds.
  • Tactile Sensitivity: Hyposensitivity to touch can result in seeking out intense tactile experiences, such as rubbing or squeezing objects. Individuals may have a higher tolerance for pain or may not notice when they are injured.
  • Proprioceptive and Vestibular Sensitivity: Some individuals may seek out intense movements or engage in repetitive behaviors that provide proprioceptive or vestibular input. This may involve activities such as rocking, spinning, or jumping.

Understanding these sensory sensations in autism is essential for creating supportive environments and developing strategies to help individuals manage and regulate their sensory experiences. By recognizing and respecting the unique sensory needs of individuals with autism, we can better support their overall well-being and enhance their quality of life.

Common Sensory Processing Challenges in Autism

Individuals with autism often experience sensory processing challenges that can significantly impact their daily lives. These challenges can manifest in various ways and affect different sensory systems.

Understanding these sensory sensitivities is crucial for creating a supportive environment and developing effective strategies to help individuals with autism thrive. Here are some common sensory processing challenges in autism:

Auditory Sensitivity

Many individuals with autism have heightened sensitivity to auditory input. They may find everyday sounds, such as loud noises or crowded environments, overwhelming and distressing.

This hypersensitivity to auditory stimuli can lead to anxiety, irritability, and difficulty concentrating. Providing a quiet, calm environment and using noise-canceling headphones can help individuals with auditory sensitivity manage their sensory challenges.

Visual Sensitivity

Visual sensitivity is another common sensory challenge in autism. Bright lights, fluorescent lighting, or busy visual stimuli can be overwhelming and cause discomfort for individuals with autism.

They may have difficulty filtering out irrelevant visual information, leading to sensory overload. Creating a visually soothing environment with soft lighting, minimizing clutter, and using visual schedules or aids can help individuals manage visual sensitivity.

Tactile Sensitivity

Tactile sensitivity refers to heightened sensitivity to touch and textures. Individuals with autism may experience discomfort or even pain when touched, especially in certain areas of their body.

They may avoid certain clothing textures, tags, or seams that feel uncomfortable. Providing clothing made from soft fabrics, using seamless or tagless clothing, and offering deep pressure input through techniques like gentle massages or weighted blankets can help individuals with tactile sensitivity.

Gustatory and Olfactory Sensitivity

Some individuals with autism may have heightened sensitivity to taste and smell. They may be extremely sensitive to certain tastes or smells, finding them overpowering or unpleasant.

This can impact their eating habits and mealtime experiences. Offering a variety of food options, introducing new foods gradually, and creating a calm and pleasant eating environment can support individuals with gustatory and olfactory sensitivity.

Proprioceptive and Vestibular Sensitivity

Proprioceptive sensitivity refers to an individual's awareness of their body position and movement, while vestibular sensitivity relates to their sense of balance and spatial orientation.

Some individuals with autism may have difficulties with motor coordination, experiencing challenges with activities that require balance, coordination, or changes in body position. Providing opportunities for sensory integration activities, such as swinging or jumping on a trampoline, can help individuals with proprioceptive and vestibular sensitivity.

Understanding and addressing these common sensory processing challenges in autism can significantly improve the quality of life for individuals on the spectrum. By creating a sensory-friendly environment and implementing supportive tools and techniques, individuals with autism can navigate their daily lives more comfortably and effectively.

Impact of Sensory Processing Disorder on Daily Life
