What is Sensory Processing Disorder?

Sensory Processing Disorder (SPD) is a condition that affects the way the brain receives and processes information from the senses. Individuals with SPD may have difficulty interpreting and responding to sensory stimuli, such as touch, sound, smell, taste, and visual input. This disorder can significantly impact daily functioning and overall quality of life. In this comprehensive guide, we will delve deeper into the intricacies of Sensory Processing Disorder, its subtypes, symptoms, causes, diagnosis, and potential treatment options.

To truly understand SPD, it is essential to explore the different subtypes or patterns of sensory processing that individuals may exhibit. Sensory Overresponsivity (SOR), also known as sensory defensiveness, is one such pattern where an individual may show heightened sensitivity to sensory input. They may react strongly or negatively to certain stimuli, such as loud noises, scratchy fabrics, or strong smells. Everything seems magnified or overwhelming to them.

On the other hand, Sensory Underresponsivity (SUR) is characterized a difficulty in noticing or responding to sensory input. Individuals with SUR may appear uninterested or unaware of their surroundings. They may not respond appropriately to pain or temperature sensations, requiring external cues to prompt a reaction.

Lastly, Sensory Seeking (SS) refers to a pattern where individuals actively seek out sensory stimulation. They may display impulsive or excessive behaviors such as spinning, jumping, or seeking out intense tastes or textures. This subtype can sometimes be misunderstood as hyperactivity or poor impulse control.

It is important to note that these subtypes are not mutually exclusive, and individuals with SPD may exhibit a combination of these patterns in varying degrees. Now let’s delve into the various symptoms associated with Sensory Processing Disorder.

Symptoms of SPD can manifest across various sensory domains and may differ from person to person. In the tactile domain, individuals may experience discomfort or aversion to certain textures, fabrics, or tags in clothing. They may avoid activities that involve touching or being touched, such as hugs or handshakes. Alternatively, they may seek out intense tactile input, engaging in activities like rubbing their hands on surfaces or pressing their bodies against objects.

In the auditory domain, individuals with SPD may be highly sensitive to noises and find them overwhelming. They may cover their ears or become easily startled sudden or loud sounds. In some cases, they may struggle to filter background noises, finding it challenging to focus in noisy environments.

In the visual domain, individuals may display sensitivity to bright lights or certain visual patterns. They may squint or avert their gaze in response to intense visual stimuli. Similarly, the olfactory domain can also be affected, with individuals exhibiting aversion or seeking out certain smells. For instance, they may find certain perfumes, cleaning products, or food odors intolerable.

In the gustatory domain, individuals may have selective eating patterns, finding certain tastes or textures intolerable. As a result, they may limit their diet to a few specific foods, causing potential nutritional concerns.

Individuals with SPD may also experience challenges related to proprioception, which refers to our body’s awareness of its position and movement. Proprioceptive difficulties can manifest as poor coordination, clumsiness, or difficulties with fine motor skills. They may struggle with activities like tying shoelaces, handwriting, or using utensils.

There is growing evidence suggesting different factors that may contribute to the development of Sensory Processing Disorder. While research is ongoing, genetic and environmental factors are believed to play a role. Certain genetic variations or mutations may predispose individuals to sensory processing difficulties. Additionally, prenatal factors such as maternal stress or exposure to toxins during pregnancy may contribute to the development of SPD.

Diagnosing SPD can be complex as there is currently no standardized diagnostic criteria or specific medical tests to identify the condition. However, healthcare professionals, including occupational therapists, may use standardized questionnaires, interviews, and direct observations to assess an individual’s sensory processing patterns. They will assess the individual’s responses to different sensory stimuli, their behavior, and their level of functional impairment in everyday activities.

Treatment for Sensory Processing Disorder typically involves occupational therapy, which focuses on providing strategies and interventions to help individuals navigate and cope with sensory challenges. Occupational therapists work collaboratively with individuals and their families to develop individualized sensory diets or intervention plans tailored to their specific sensory needs.

Sensory integration therapy is a commonly utilized approach within occupational therapy. It involves engaging individuals in purposeful activities that provide the appropriate level of sensory input. This therapy aims to help individuals regulate their sensory responses and develop adaptive coping mechanisms.

Other strategies may include environmental modifications, such as creating sensory-friendly spaces, reducing environmental triggers, or providing sensory tools and equipment, such as weighted blankets or noise-canceling headphones. Cognitive-behavioral therapy and parent/caregiver education and support are also essential components of comprehensive SPD treatment.

Sensory Processing Disorder is a complex condition that affects the way individuals perceive and respond to sensory information. It can manifest in various ways, and individuals may exhibit different sensory processing patterns, including sensory overresponsivity, underresponsivity, or seeking behavior. The symptoms can affect multiple sensory domains, such as touch, sound, sight, smell, taste, and proprioception. While the exact causes of SPD are still under investigation, genetic and environmental factors are believed to contribute to its development. Through the assistance of occupational therapy, individuals with SPD can learn effective coping strategies and interventions to improve their daily functioning and overall quality of life. It is essential to consult with healthcare professionals experienced in sensory integration and occupational therapy for a comprehensive assessment and guidance on appropriate treatment options for individuals with Sensory Processing Disorder.
