Understanding Sensory Processing Disorder and Its Impact on Children

Sensory Processing Disorder (SPD) affects the way children interpret and respond to sensory information from the world around them. Unlike typical processing, where sensory input is seamlessly integrated, SPD leads to different processing, which can significantly impact various developmental stages. Sensory processing differences includes a spectrum from hypersensitivity (over-responsiveness) to hyposensitivity (under-responsiveness) across all senses, affecting how a child experiences their environment.

What Are Sensory Issues?

Sensory issues refer to atypical reactions to sensory input, which can manifest as either hypersensitivity or hyposensitivity to stimuli. These reactions can affect any of the eight sensory domains, leading to challenges in how individuals perceive the world through their senses. Such issues can impede daily functioning and affect a child’s ability to engage with their environment and others, often resulting in a skewed perception of stimuli as overly intense or insufficient.

“As a physical therapist, I often see that everyone falls somewhere on the sensory spectrum, varying from hypersensitive to hyposensitive across all senses. When these sensory processing challenges go unrecognized, they can manifest in various issues such as general anxiety disorders, social anxiety, and decreased social interaction skills. By acknowledging and addressing these sensory variations early on, we can mitigate their impact on daily life and promote a better quality of living for individuals facing these challenges.”

The Eight Senses and Sensory Processing

Traditionally, we think of the five senses: sight, sound, smell, taste, and touch. However, SPD also involves three additional senses: vestibular (balance), proprioceptive (body position), and interoceptive (internal body states). Understanding how disruptions in any of these senses can affect children is crucial:

Visual (Sight): Children may be overwhelmed by bright lights or unable to focus on visual details, impacting activities from focusing on a book to participating in outdoor play.
Auditory (Sound): Hypersensitive children may find noisy environments like classrooms unbearable, while hyposensitive ones might not notice when spoken to directly.
Olfactory (Smell): Some children might be offended by strong odors, affecting everything from social interactions at the lunch table to participation in art classes.
Gustatory (Taste): Picky eating is common, with certain textures or flavors being intolerable, hindering nutritional intake and meal enjoyment.
Tactile (Touch): A tag on a shirt or unexpected touch might be unbearable for some, while others seek excessive tactile stimulation.
Vestibular (Balance): Difficulties can present in coordination and risk-taking, from avoiding playgrounds due to dizziness to seeking high-risk, spinning activities.
Proprioceptive (Body Position): Children may struggle to understand their body’s position in space, leading to clumsiness or constant physical contact.
Interoceptive (Internal State): Challenges interpreting hunger, thirst, or even the need for the bathroom can result in significant stress for both children and parents.

Impact Across Developmental Stages

Toddlers

In this early stage, SPD can manifest as extreme reactions to simple stimuli like diaper changes or bathing. A hypersensitive toddler may exhibit distress with new textures, while a hyposensitive child might appear disengaged or pose safety risks due to an impaired sense of danger. These sensory challenges often translate into communication barriers and developmental delays as toddlers explore their world.

Preschoolers

As children enter preschool, the demand for social interaction and structured activities increases. A child with SPD might find it challenging to participate in group play or circle time, leading to social isolation. Hypersensitive children may react strongly to the noise and chaos, whereas hyposensitive children often find it hard to engage in activities requiring fine motor skills or following rules.

School-Aged Children

For school-aged children, SPD often impacts academic performance and peer relationships. Children may struggle to focus on their studies due to an inability to filter out background noise or become overstimulated by busy classrooms. Hypersensitivity can lead to anxiety or avoidance behaviors, while hyposensitivity might manifest as a lack of alertness or engagement in lessons. Difficulty with sensory processing can also affect a child’s self-esteem and social interaction skills.

Adolescents

During adolescence, the impact of SPD can extend into more complex social, academic, and emotional issues. Teenagers must manage sensory processing difficulties alongside the typical challenges of identity and independence. They may avoid social situations out of fear of overstimulation or engage in risky behaviors seeking sensory input. These issues can affect academic performance, friendships, and emotional well-being, leading to increased risk of mental health problems if not managed appropriately.

What is Sensory Overload?

Sensory overload occurs when an individual experiences an overwhelming amount of sensory input that their brain cannot effectively process or filter. This is common in individuals with hypersensitivity, where normal environmental noises, lights, or touch can become unbearable. Symptoms may include irritability, anxiety, withdrawal, or even meltdowns as the person struggles to cope with the barrage of sensations. Sensory overload is a significant hurdle for children with SPD as it can lead to avoidance of certain environments or activities.

Possible Complications of Sensory Processing Disorder

SPD can lead to various complications if not managed properly. These can include developmental delays in motor skills, speech, and learning abilities. Additionally, social isolation and behavioral challenges may arise due to difficulties in interacting with peers and adjusting to new environments. Emotional issues such as anxiety, depression, or low self-esteem can also develop, particularly if sensory processing difficulties go unrecognized or inadequately addressed throughout critical stages of development.

Controversies About SPD

The existence and diagnosis of Sensory Processing Disorder remain controversial within the medical and psychological communities. Some experts argue that SPD overlaps significantly with other diagnoses such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD), raising questions about its classification as a standalone disorder. Concerns also arise around the lack of standardized diagnostic criteria and scientific research supporting distinct biomarkers for SPD, making diagnosis and treatment approaches varied and sometimes disputed.

How to Help a Child with Sensory Processing Difficulties

Supporting a child with SPD involves a multifaceted approach tailored to their unique needs. Occupational therapy is often recommended to help children develop coping strategies and improve their sensory integration skills. Physical therapy can help with deficits that can arise in coordination and balance – often seen with diminished playtime with peers. Playing is crucial for brain development for children and when children avoid certain situations, issues usually arise in various areas such as with balance and coordination. Creating a structured and predictable environment can reduce instances of sensory overload. Parents and educators are encouraged to collaborate on personalized strategies, employing tools like weighted blankets, fidget toys, or noise-canceling headphones. Encouraging open communication about sensory experiences and promoting self-awareness can empower children to advocate for themselves and navigate challenges more effectively.

“Children with sensory processing issues may find it challenging to engage in play with their peers, often avoiding activities like running, climbing, or sports that are essential for developing balance and coordination. This can lead to deficits in motor skills, as their avoidance of physical interaction limits opportunities for growth and the acquisition of crucial developmental milestones.”

Understanding Sensory Processing Disorder and its impact on children’s developmental stages helps caregivers and educators tailor supportive environments. Recognizing the signs of hypersensitivity and hyposensitivity across the spectrum can aid in creating adaptive strategies and therapies that enhance the well-being and development of these children. Early intervention, personalized support, and continuous advocacy are crucial to empowering children with SPD to thrive throughout their formative years.
